10 Best Bicycle Part Stores of 2026

Jenson USA has been serving cyclists since 1994, offering a huge selection of bikes, parts, and accessories from top brands. You can shop online for delivery straight to your door or visit one of their two retail locations in Corona and Riverside, California.

Zero-stress online shopping here

From the moment you land on their site, it's clear that Jenson puts thought into making your shopping experience easy and enjoyable. The search function is quick and intuitive - start typing, and it automatically suggests relevant products to help you zero in on exactly what you need. Not sure where to start? Their site is neatly organized by categories like bikes, components, apparel, and accessories, with brand-specific browsing options too.

Get insights from experts and riders just like you

One standout feature is Gear Stoke, a constantly-refreshing feed of customer favorites with short, honest reviews on products like Fox Racing Shox, Specialized's Hover Expert Alloy Handlebar, Wolf Tooth's Supple Bar Tape, and many more. It's a little bit addictive - the kind of scroll that keeps showing you new products the longer you linger. For even more insight, Jenson's blog serves up in-depth product guides and reviews, plus a categorized list so you can quickly find topics that matter to you. You'll also find an A-Z brand directory, both in list form and as a clickable visual catalog, which makes finding your favorite manufacturer a breeze.

Something for every cyclist

In order to make an apples-to-apples comparison across all of the bike part stores on our list, we looked at three typical items: tubes (frequently replaced), saddles (a common upgrade), and derailleurs (a specialized part). Jenson knocks it out of the park across all three. Here's what we found:

• Tubes: in the traditional tubes category (not tubeless, kits), there were 54 options ranging in price from $2.99 for the Foundation MTB to $50.31 for the Pirelli Angel SmartTUBE X 700c (a 10% discount from the MSRP of $55. 90).
• Saddles: Jenson's inventory consisted of nearly 200 saddles, priced from $9.99 (the Juliana Segundo CroMo women's model, deeply discounted from the MSRP of $40) to $499.99 (the Fizik Vento Argo 00 Adaptive Saddle).
• Derailleurs: for $14.99, Jenson listed the SRAM SX Eagle Rear Derailleur (with an MSRP of $85). The highest-end option among the 187 products in the category was also an SRAM product, the Red 1x AXS XPLR E1 13-speed, priced at $770.

They really want you to get the best price

If you're hunting for deals, Jenson USA makes it simple: just check the "Sale" tab to instantly see discounted items. And if you're price-conscious (who isn't?), their price-matching policy is impressive: if you see the same product for less from a competitor they'll try to match it... instantly. Going above and beyond even that, if you order bike parts from Jenson and they drop their own price within 30 days, they'll refund the difference. That's a level of customer-centric care that you just don't see from most online retailers, bike-related or beyond.

Sales and discounts can also help you save

Look around for even more savings opportunities. We spotted a "click for limited time special offers" at the bottom of the site; those included free shipping on select bikes and "custom rides at great prices". Maybe when you're shopping, those offers will extend to the bike parts you need. You might even get an extra discount if the spin-and-win odds are ever in your favor. During our visit, the possibilities included discounts of 5%-15% off a first-time order. Plus, orders over $50 always ship free, and you can also choose free in-store pickup if that's more convenient.

Generous 90-day return window

Returns are straightforward, too. The policy gives you 90 days to send back items in new, unused condition for a full refund. If you return something in used condition, expect a restocking fee of at least 20%. Also, if you're returning a bike rack, frame, wheel, or a complete bike, you'll have a return shipping fee of $38.99 to $99.99; all other parts and accessories have an $8.99 return fee (to cover the postage). It's pretty generous compared to many other bike part retailers.

5-star ratings from tens of thousands of happy customers

Customer feedback for Jenson USA is overwhelmingly positive. On Trustpilot, they average 4.6 stars across a staggering 50,000+ reviews. (If you can't do the mental math on that - we can't either - that's over 42K 5-star ratings). They have a fantastic reputation for resolving issues, often responding directly to negative reviews to make things right. But, any complaints are few and far between, with most customers saying things like "I've been buying from Jenson for years" and "Amazing how fast I got my order". So, it'll come as no surprise that this bike shop continues to have an "A+" and accreditation from the Better Business Bureau as well.

Best bike parts store on the internet

From killer selection to customer service that actually feels personal, Jenson USA makes it easy to keep your bike in peak condition - and maybe even a little more fun to ride. Whether you're replacing a worn-out derailleur, hunting down a rare saddle, or just browsing Gear Stoke for your next upgrade, you'll find plenty to love here. Add in their price-match promise, fast shipping, and those little surprise savings opportunities, and it's no wonder so many riders say Jenson USA is their go-to shop. If you're serious about your ride (or just want the parts that will keep it rolling smoothly), this is one bike parts shop you'll want bookmarked.

Cambria Bike has been serving cyclists since 1986, starting as a single shop dedicated to helping local riders get the most out of their bikes. Today, they've grown into a trusted name both in-store and online, offering an extensive lineup of bikes, parts, and gear from well-known brands. Whether you're shopping for your daily commute, a weekend trail adventure, or your next race, their site makes it easy to find exactly what you need - and score a deal while you're at it.

Super-smooth online shopping experience

From the moment you land on their site, you'll notice how intuitive it feels. The search bar is quick and smart, suggesting popular categories, products, and pages as soon as you start typing. Prefer to browse? You can jump into clearly marked categories like bikes, components, wheels and tires, apparel, and accessories, or browse by brand if you already have a favorite manufacturer in mind.

Measures up extremely well with respect to price and selection

It can be challenging to compare one bike parts store to another, so to make it a fair competition, we looked at three main product categories at each retailer. We chose one everyday item (tubes), one often-upgraded item (saddles), and one specialized part (derailleurs). Cambria Bike performed extremely well with respect to pricing and selection:

• Tubes: Cambria Bike had 80 products to choose from, ranging in price from $3.89 to $14.99 for the CBO Generic 26" Butyl Tube, to $69.99 (marked down from $89. 99) for the Mr. Tuffy E-Bike Tire Liner in Teal (the purple liner was even more affordable at $39. 95).
• Saddles: in this category, you've got almost 200 to choose from, starting with the CBO Kids Padded Saddle in black or white for $14.95 or the Niner X3 Boost Saddle in Black for adults at $19.99 (deeply discounted from an original price of $59. 99). On the other end of the price spectrum, we were excited to see several saddle models by Fizik priced at $299.99 and $449.99 (with that latter one being $50 less than our first-place retailer, even).
• Derailleurs: you'll find both parts like bolts and converters as well as full kits in this section, with over 200 items total. A full Shimano Tourney TY 300 6/7 Spd MTB Rear Derailleur BMX Mount was discounted to $8.99 at the time of our visit. On the high side, Shimano's Dura-Ace Di2 R9250 12-Speed Rear Derailleur was priced at $814.99.

Price matching, sales, and free shipping on $50+ will save you money

How about saving some money? No problem at Cambria Bike. There's a Sale section where you can find discounted products across their entire catalog - perfect if you're looking to stretch your bike parts budget a little further. Cambria Bike also offers price matching - they humorously call it a "Price Smash" - so if you spot the same item for less somewhere else, they'll do their best to match it. And, don't overlook the free shipping: as long as your order is over $50 and delivered within the lower 48 United States, it'll be delivered at no cost, and with no coupon code required.

365 days for returns?! Yes

The return policy here is one of the most generous you'll find. You have up to 365 days from your purchase date to return items in new, unused condition with original packaging for a full refund. The only exceptions are customized products. The process is easy to initiate through their clearly marked "return an item" link at the bottom of the site, and they'll even help you navigate manufacturer warranty claims if you need it.

Reputation is stellar (literally)

You can feel very confident that Cambria Bike is a parts shop you can trust. Starting with an "A+" rating and accreditation from the Better Business Bureau, the company demonstrates day in and day out that they genuinely care about getting the right bikes and parts to riders. You'll also see that reflected in the shop's Trustpilot reputation: an excellent average of 4.7 stars spanning nearly 2,000 ratings. Comments left within just a few days (hours, even) of our evaluation praise Cambria Bike's fast shipping, competitive prices, and even the inventory which often has hard-to-find items (one person mentioned women's Pearl Izumi pants, for example). From first-time customers who were thrilled to get a quick, helpful response when wanting to make a change after placing their order, to long-time fans of Cambria Bike who wouldn't dream of shopping anywhere else for bike tires, gloves, brake pads, and more, it's easy to see that you're likely to become a loyal fan too.

A must-shop bike parts store

Cambria Bike offers an easy-to-use website, an excellent selection of bike parts and accessories, and customer service that's clearly at the top of its game. Add in those competitive prices, generous return policies, and terrific reputation, and you'll understand why it's a shop that deserves a spot near the very top of your list for bike parts. (That's where it lands on ours).

Performance Bicycle is a Northern California-based cycling community and retailer that's been helping riders get the most from their gear since 1981. What started as a family-run catalog business has evolved into a major online destination for bikes, parts, and accessories. In 2019, Performance Bicycle joined the AMain Sports & Hobbies family - a well-known name in the hobbies and sports world - and while all but one of their physical stores have closed, their online presence remains strong. Today, they're focused on delivering great products, solid deals, and genuine support for cyclists everywhere.

Easy-to-navigate shopping experience

The Performance Bicycle site is simple, straightforward, and geared (see what we did there?) toward helping you find what you need quickly. Categories like Accessories, Bikes & Frames, Clothing, Maintenance, Parts, and Tires & Tubes make it easy to jump right in. You'll also find sections for new arrivals, special offers, and top-selling products - plus a search bar that suggests products and categories as you type. (Side note: we thought it was cute that items like shifters, brakes, handlebars, saddles/seats, and so on were grouped into the category of "Cockpit" on the left-hand side of the page).

Helpful resources for cyclists

If you're the kind of rider who likes to do some research before making a purchase, Performance Bicycle has you covered. Their blog offers a wide range of topics (like how to choose the right road tire or the easiest way to wax a bike chain), and their FAQ section answers questions on everything from financing and returns to rewards points and shipping restrictions. You'll also find details about the VIP rewards program, sponsorship requests, and warranty information - all without having to dig around the site.

Incredible selection across a range of bike parts

Wondering how this bike parts store measures up with respect to selection? Across all of the retailers we evaluated, we looked for the inventory and pricing in three categories: tubes (a commonly-bought item), saddles (a popular upgrade), and derailleurs (a specialized part). Take a look at what Performance Bicycle had to offer:

• Tubes: the selection here was above and beyond many rival stores at nearly 300 products. They ranged from $0.99 for a Forte 12.5" Inner Tube to $50.31 for the Pirelli Angel SmarTUBEX Extra Durable Inner Tube. Performance's inventory went a step above and beyond, offering bulk boxes of tubes for about $350 (but, oddly, they didn't seem to specify exactly how many tubes were in the box).
• Saddles: grouped together in the category of Saddles & Seats, this bike parts shop wowed us with an inventory of almost 600 options (though some of those items were accessories like saddle bag mounts or charms, FYI). You might spot a Giant Juvenile MTB Saddle for $15, the Selle Italia SLR C59 for $579.99, or just about anything in between.
• Derailleurs: again, bearing in mind that you'll see both full derailleur sets as well as compatible replacement parts like hangers and pulleys, you can't help but be impressed by the 950 choices offered by Performance Bicycle. Whatever you're looking to pay, you'll likely find it - but we were pretty gobsmacked by the SRAM RED XPLR AXS Upgrade Kit with the price tag of $1,540 (and designated as "limited quantities available"...you think?).

Excellent customer service and support

Performance Bicycle has built a reputation for going above and beyond for customers. Whether you're a seasoned cyclist or just getting into the sport, their team aims to match you with the right gear and ensure you have what you need to ride with confidence. That dedication shows in their customer interactions and long track record of satisfied shoppers. To that end, Performance Bicycle makes it easy to reach out. You can use their contact form, call during extended business hours (6am-5pm PST, Mon-Fri), or start a live chat for quick answers. They're also active on six different social media platforms (from Facebook for the "seasoned" generation to TikTok for the "newer" riders), so it's easy to connect in whatever way works best for you.

Free shipping on orders of $99+, 30-day return window

Your order from this bike parts store will ship for free if it's at least $99 (so you might as well stock up). We also appreciate their return policy: you've got 30 days for a refund or store credit, and they only charge a 15% restocking fee "in very rare circumstances". They go the extra mile in this area too, saying that they "understand that life happens" and invite customers to reach out and get a custom solution if the return can't be made within that 30-day timeframe.

Outstanding customer feedback

With an impressive 4.9-star rating average from more than 2,300 Google reviews alone, and a BBB-accredited "A+" rating held since 2007, Performance Bicycle clearly delivers on its promises. Customers regularly praise their fast shipping, helpful staff, and quality products. This particular rider left a compliment we really loved: "I have used Performance Bicycle for years. I have purchased bikes and merch several times over. Even [their] own brand products are some of the best I've ever used."

A customer-centric, well-stocked choice for your cycling needs

Performance Bicycle offers a great mix of value, selection, and service. While we'd love to see more customer reviews on individual product pages (since most of them are shown as "not yet reviewed"), Performance's stellar reputation and commitment to the cycling community make them a retailer worth considering. That's why they've earned a strong spot in our rankings for bike parts stores.

Nashbar has been around the block - literally and figuratively - for decades. What began in 1974 as a modest mail-order business has grown into a go-to online destination for bike riders of all stripes. Nashbar is known for carrying thousands of products across major brands like Shimano, Bell, Mavic, Garmin, Yakima, and more. Their reputation has been built on making gear accessible at fair prices, and that philosophy is still alive today.

Part of the AMain family

Nashbar's credibility today also ties back to its 2019 acquisition by AMain Sports & Hobbies. After a bumpy period under Advanced Sports Enterprises (ASE), AMain stepped in to rescue the brand in February 2019, picking up Nashbar's web presence, Performance Bicycle's e-commerce platform (who you'll see reviewed separately), and the associated trademarks of both. (So, if you see some similarities between Nashbar and Performance while you're browsing for bike parts, now you know why). AMain shares its "A+" rating and accreditation from the Better Business Bureau with both sub-brands.

Online shopping is easy-breezy

So, let's take a closer look at the Nashbar experience when shopping for bike parts. It's refreshingly straightforward: you can search by keyword or even by part number if you already know exactly what you're looking for. Or you can browse through clear categories like Accessories, Bikes & Frames, Apparel, Accessories, Tools, and Tires & Tubes. If you're hunting for something more specific, filters let you drill down by brake type, speed, brand, price, product status, and even gender-specific gear. That makes it easy to go from "I need something for my bike" to "here's exactly what I want" in just a few clicks. And, you'll get free shipping as long as your order is at least $99 (which, let's be honest, that's all too easy to do when you're buying bike parts...).

Excellent selection of bike parts across many brands

It won't be a surprise that Nashbar's selection is fantastic across the three product categories we surveyed across all of the bike parts stores on our list - there's a reason why its sister site is almost at the top of our list, after all. However, it's worth mentioning that the selection here is a bit smaller than Performance Bicycle (but not by much). Here's what you'll find at Nashbar for those comparison items:

• Tubes: Nashbar stocks close to 300 inner tube options, making it one of the deeper selections you'll find online. Prices start around a dollar for basics like the Forte 12.5" Inner Tube and climb up to just over $50 for premium models such as the Pirelli Angel SmarTUBEX Extra Durable Inner Tube. You'll even run across bulk packs priced in the $350 range - though, curiously, the site doesn't make it clear how many tubes come in the case.
• Saddles: Under the Saddles & Seats category, you'll discover over 500 listings. Not every item is a traditional saddle (some are mounts or accessories), but the range is still impressive. Bargain hunters might snag something like the Selle Italia GT-1 Comfort Saddle for $25, while riders chasing ultralight performance could consider the Selle Italia SLR C59 at $579.99 - with hundreds of other options spread between those extremes.
• Derailleurs: If it's drivetrain parts you're after, Nashbar doesn't disappoint. Between complete derailleur systems and small replacement pieces like pulleys and hangers, the catalog stretches to roughly 900 products. Prices cover the full spectrum, but one standout we noticed was the SRAM RED XPLR AXS Upgrade Kit ringing in at $1,540 - and flagged as "limited quantities available," which made us smile given the steep tag.

Decent return policy, easy-to-reach customer service

Getting help is pretty simple at Nashbar. You can connect via phone, live chat, or an online form if you've got questions about your order. Returns are also fairly straightforward. If your item is new, unused, and in its original packaging, you can send it back for a refund or store credit without much hassle. If it's been more than 30 days since your purchase, you'll need to talk with customer service first - and in some cases, you may be hit with a 15% restocking fee. Not ideal, but not the worst, either.

Customers love shopping here

Beyond the shared "A+" from the BBB, Nashbar itself gets loads of praise from happy customers, both new and long-term. Across nearly 300 ratings on Google reviews alone, the bike parts shop has earned a close-to-perfect average of 4.8 stars. "Have used them for decades", "Delivered overnight and saved my vacation", and "Love my Nashbar bike that has thousands of miles on it" are just part of the glowing praise we spotted.

Where Nashbar could improve: rider resources

One area where Nashbar lags a bit is in rider education and resources. Aside from a basic "Bicycle Assembly" page with a couple of YouTube videos (one of which was unavailable at the time of our last check), there isn't much in the way of how-to guides, articles, or videos to help cyclists pick the right parts or learn to do their own maintenance. For a brand that's been around this long, it feels like a missed opportunity. Adding a blog, gear guides, or even quick explainer videos could take the shopping experience to the next level. (It was also surprising not to find anything like that here, since Nashbar's sister site has ample resources in that vein... but maybe AMain decided not to reinvent the wheel here... pun intended).

A dependable, budget-friendly option for bike parts

Nashbar may not be the flashiest name in bike parts, but it has staying power - and that counts for something. Between the easy-to-use site, wide product range, fair pricing, and positive reputation, it's a smart option for riders who want dependable gear without spending top dollar. We'd love to see them step up their educational resources for cyclists, but even without that, Nashbar remains a reliable stop for your next bike part purchase.

On the Nashbar website

Worldwide Cyclery made its name as a mountain-bike-only shop, and while MTB gear is still their bread and butter, they've since broadened their catalog to cover a wider range of cycling categories. From complete bikes and frames to accessories, apparel, and components, they've got plenty to browse whether you're an off-road rider or not. With three retail locations in California, Pennsylvania, and Nevada - plus a strong online presence - they've built a loyal following of riders who appreciate that the staff here are genuine enthusiasts, not just salespeople.

Not the easiest site to shop

Shopping online at Worldwide Cyclery isn't quite as streamlined as some of its competitors. For instance, when we went looking for derailleurs, there wasn't a single dedicated section; instead, we had to dig into "Drivetrain" and then filter down by front, rear, and so forth. It works, but it's a little clunkier than other bike parts stores that make it easier to see everything in one place. There's also no place for cyclists to add their feedback on individual parts; we'd love to see Worldwide Cyclery add that feature in the future, since no one knows how those rear shocks actually hold up after literally hitting the trail better than the riders who've tried them.

Good-but-not-vast selection of bike parts

In general, Worldwide Cyclery's selection across parts categories is solid, but not quite as extensive as the top-ranked retailers on our list. We looked at tubes (because everyone needs them), saddles (because everyone loves an upgrade), and derailleurs (because sometimes we need a specialized part) across all of the bike parts shops on our list, and here's what we found at Worldwide Cyclery:

• Tubes: About 100 in stock, and no "bargain basement" deals to be found. The lowest-priced option was Pirelli's SporTube 700x32 Presta Valve model for $8.90, and the most expensive was Continental's TPU Tube SV60 for $41.95.
• Saddles: About 200 to choose from, and again, nothing cheap. The most affordable saddles in stock were several models by WTB (Rocket, Volt, Silverado) for $44.95. On the other end, Worldwide had some killer deals on Fizik Vento Argo saddles at just $387.44 (or less) for various sizes.
• Derailleurs: As mentioned, it was more complicated to analyze this part because they were all grouped under Drivetrain, but we found about 130 total under the categories of Front and Rear Derailleurs. Spend $930 on the Shimano Dura-Ace RD-R9250F Di2, $39.99 on the microSHIFT R10 Shimano-compatible model, or anywhere in between.

Plenty of extras for riders

One area where Worldwide Cyclery shines is rider support. Their website is packed with how-to articles, product explainers, and video content, plus a podcast for cyclists who want more than just shopping. In their physical shops, you'll also find a demo bike program that lets you test-ride certain models before committing, as well as custom build services if you want something tailored specifically to your needs. These extras show how invested Worldwide Cyclery is in the riding community.

Shipping, returns, and policies - oh my

All orders here ship free within the US, and you'll have a 45-day window to send most items back if they're unused and in original packaging (though you'll need to cover return shipping). Bikes and frames are only eligible for store credit, so make sure you're committed before you buy. It's not the most generous policy we've seen, but it's fair enough.

You're probably going to love this shop

Customer satisfaction is zero problem here. Not only does Worldwide Cyclery have an "A+" rating from the Better Business Bureau, but their Trustpilot reviews have skyrocketed from the 3.9-star average in our previous evaluation to a just-shy-of-perfect 4.9 stars now. Happy riders report getting expedited shipping fees refunded when an order was delayed, getting compassionate help replacing a bike totaled in an accident, and finding that the combo of onsite explainer videos and phone-based live help was a game-changer.

Smaller inventory balanced out by excellent customer support

Worldwide Cyclery remains one of the best bicycle parts stores for mountain bikers, and they've expanded enough to serve a broader range of cyclists too. While their parts selection isn't quite as large as bigger rivals and the site's navigation takes more effort, the knowledgeable staff, wealth of rider resources, and extras like demo bikes and custom builds make them a solid option for riders who want more than just a shopping cart.

On the Worldwide Cyclery website

If you've ever wished for a bike parts shop that skips the chit-chat and just gets down to business, Modern Bike might be your new favorite. This Des Moines-based retailer doesn't waste time with "About Us" fluff or rider how-to articles: the website basically says "here's what we've got" and delivers - big time. With tens of thousands of parts in stock, competitive pricing, and some really smart site tools, this store is steadily climbing in our rankings.

Fancy? No. Well-stocked? Yes

When we compare bike parts shops, we often look at selection and pricing on three popular categories: tubes, saddles, and derailleurs. Modern Bike impressed us across the board:

• Tubes: Modern Bike blew us away with an inventory of more than 1,000 tubes, ranging in price from the Sunlite Utili-T for $3.99 to the 50-tube bulk box of Sunlite tubes for $565.99 - and just about everything you can imagine in between.
• Saddles: At this bike parts store, they're all lumped together in the "Seats" category, with almost 1,400 to choose from. You'll find cute kids'/juvenile saddles for under $15 and a good selection of adult seats for under $20, if you're looking for the lowest cost. But, if you're going for the big upgrade, Modern Bike has your back(side) with the top-of-the-line Selle Italia SLR C59 with CarboKeramic Rail (and the "anatomic central relief area" we all know and love..) for $579.99.
• Derailleurs: With a selection of 1,800+, you're almost guaranteed to find the right one for your bike here. Just be aware that the category includes hangers, parts, and assemblies; there are about 150 front derailleur options and 250 rear ones. A few examples are the Sunrace FD-M2S for just $8.44 and the top-of-the-line Shimano Dura-Ace RD-R2950F Di2 for $814.99.

Compatibility tool is a big plus

One standout feature here is the compatibility checker: plug in your bike's details, and you'll only see parts that will work with your ride. Unless you're rocking a heavily customized Frankenbike, that's a big time-saver. That's also important because most bike parts listed by Modern Bike don't have any customer reviews. But, we appreciate that the store allows shoppers to leave feedback (like the perfect 5-star score across 5 reviews of the Shimano Altus M310 rear derailleur).

Extremely competitive on price

Pricing is another strength at Modern Bike -like the Fizik Vento Argo 00 Adaptive Saddle that sells for about $450 at most shops, but just $399.99 here. Shipping is straightforward too - usually $6.99 within the continental US, but any item marked "free shipping" makes your entire order ship free.

Return policy is standard

Need to send back your bike parts? Modern Bike's policies are reasonable: you've got 30 days to return new, unused parts in their original packaging.

It's hard to argue with over 1,000 5-star reviews

As for reputation, Modern Bike gets mostly high marks. There's a "B-" from the BBB for not responding to a single complaint, but with only one filed in recent years, we're not too worried. Customer reviews elsewhere are much more telling: Google shows a 4.9-star average across 1,100+ shoppers, enough to earn a "top quality store" designation. A few grumbles on Trustpilot and elsewhere mention having to pay return shipping even when Modern Bike made the mistake, but that's balanced by literally hundreds of 5-star reviews. On the whole, cyclists love this store.

Perfect place to shop for bike parts - with no distractions

Modern Bike may not hold your hand with glossy guides or how-to content, but if you just want excellent selection, super-competitive pricing, and a solid reputation backing it all up, this is a parts shop worth checking out. That's why we've moved it up in our list: keep an eye on Modern Bike, because it's become one of the most promising mid-tier contenders in the bike parts world.

On the Modern Bike website

Bike Parts, the online storefront of Peak Cycles in Golden, Colorado, has been steadily leveling up in the cycling retail space. This shop used to be at the very bottom of our rankings, but a series of website upgrades and better overall customer feedback have moved it into the "worth a look" category. With a brick-and-mortar location in historic downtown Golden and a polished e-commerce site offering more than 55,000 products, Bike Parts is trying to balance hometown service with big-time inventory.

Surprisingly broad inventory

If you like having options, you'll find plenty here. Bike Parts carries everything from apparel and tools to complete bikes, with recognizable brands like Specialized, Giant, Liv, and S-Works in the mix. We drilled into some of the parts categories that every cyclist shops for sooner or later, and here's what we found:

• Tubes: We found more than 400 options, from the $5.29 Beady Butyl tubes to 50-count bulk cases by Beady and Specialized for around $350.
• Saddles: Whether you're looking for an upgrade to speed or comfort (or both), you'll get more than 650 in-stock saddle choices at Bike Parts. We spotted a crack sale on Specialized's Expedition Gel saddle in black for $19.98 (down from $50); on the high end were several styles by Specialized and Selle Italia for $475 to $480, plus the Fizik Vento Argo 00 we saw on competitor websites (priced here and there at $449. 99, though some rivals had it for less).
• Derailleurs: Bike Parts helpfully separates this category into subgroups, like "Front", "Rear", "Hangers", and "Parts", and we love not having to sift through items we don't want. There were 88 in-stock front derailleurs and 181 available rear derailleurs, with prices ranging roughly from $6.99 to $930.

That range gives riders flexibility, whether they're hunting for a budget-friendly replacement or a premium upgrade.

Upgraded shopping experience... mostly

In its latest version, Bike Parts' website feels fresh and easy to use. You'll see right away if an item is in stock or only available in the warehouse (with estimated ship dates clearly displayed), and you can filter out-of-stock products so you're not chasing something unavailable. One funny quirk: scroll to the very bottom of the site and you'll notice a typo in the footer - "Manufactureres" instead of "Manufacturers." (Not a dealbreaker, but worth a chuckle).

Everything you need to know about shipping, returns, and price adjustments

Orders over $75 qualify for free shipping, and local customers can choose free will-call pickup from the Golden shop. The return policy is pretty fair: you'll have 30 days to send back items in new, uninstalled condition for an exchange, refund, or store credit. From 30-60 days, you may still get a return approved but with a 15% restocking fee. Bikes are more complicated: they can only be returned in "exceptional circumstances," within 7 days, and there's a 6% restocking fee. On the plus side, Bike Parts will honor post-purchase price drops: if something you buy goes on sale within 15 days, you can request a price adjustment even if your order has already been processed.

Reputation and reviews are trending upward

Unlike many competitors, Bike Parts doesn't have a separate BBB rating. Parent shop Peak Cycles is listed but marked "not rated" due to the BBB not having enough info to make a judgment call. Still, customer feedback elsewhere is encouraging. Yelp shows a 4.2-star average across 50+ reviews for the Golden location, while Bizrate reviewers give the online shop a solid 9.1 out of 10 across more than 60 post-delivery ratings. In total, over 400 overall reviews are out there, which shows that Bike Parts isn't some no-traffic ghost site: people really are ordering here, and most seem happy with the outcome.

Worth a look

Bike Parts has come a long way since our last evaluation, climbing from a disappointing one-star showing to a mid-pack rating today. A bigger pool of customer feedback and perhaps a BBB rating/accreditation would push this shop higher, but for now, it's a solid option. With tens of thousands of cycling products, free shipping over $75, and the backing of a well-reviewed local bike shop in Colorado, Bike Parts is worth a try for your next order.

Bicycle Warehouse has been around since 1992, when it first opened as Mountain Bike Warehouse in San Diego. Over time, it's grown beyond just mountain bikes into multiple stores, related businesses, and an online catalog. The mission here is simple: "to inspire your passion to ride so you enjoy more fitness, freedom and fun." That's a great sentiment, but how does the shopping experience stack up? Let's take a closer look.

Prices and inventory are okay overall

You'll find a mix of strong and weak spots in Bicycle Warehouse's inventory. For some categories, the variety is fairly limited, while others rival the biggest online bike shops:

• Tubes: With an inventory of just 106 products in the category, Bicycle Warehouse comes up a bit thin. They ranged in price from $1.95 (Kujo 26") to $37.71 (Pirelli Scorpion SmarTube); other brands included Giant, Surly, Specialized, and Slime.
• Saddles: Grouped together as "Saddles & Seats", you'll see over 500 possibilities at Bicycle Warehouse (but it includes saddle covers, seat clamps, and other parts too). Lowest-priced saddles include several youth seats for under $25 and the GT-1 L2 FeC Alloy for $25 (on sale); high-end options available were the SLR C59 for $579.99, the Vento Argo 00 Adaptive Saddle we saw at most rival bike shops (at the same price: $449. 99), and several S-Works models for $475.
• Derailleurs: From parts to full kits, you'll see over 400 choices in the inventory. The microSHIFT M21 rear derailleur was priced at $11.99 on sale, while the Campagnolo Super Record Wireless rear derailleur was nearly $1,000 (and wasn't offered at most of the bicycle parts stores on our list). Whatever you're looking to spend, Bicycle Warehouse probably has more than one option for you.

Perks for new shoppers

How about a $25 off coupon? If you're a first-time Bicycle Warehouse shopper, you can enter your email in the pop-up and get that discount on any order over $100. That gives you an incentive to test out the site, especially if you're stocking up on multiple parts at once. On top of that, the site has some helpful extras like "How to Buy Bike Tubes" and "Learn More about Bike Derailleurs" - great for beginners who want guidance before making a purchase.

Shipping is free with a minimum

Orders over $99 ship free within the continental US (excluding bikes and oversized items). That's a lower threshold than some bike shops, so you won't have to add as much to your cart to get free delivery.

Returns are fairly standard

Bicycle Warehouse offers the usual return policy. Most purchases can be returned within 30 days for a refund, with a prepaid return shipping label provided (a $10 fee is deducted unless the item was defective or incorrect). Bikes are more limited, though: you only get 14 days or 14 miles for e-bikes. No surprises here.

Store and customer service are easy to access

If you're near San Diego, you may already recognize their Pacific Beach warehouse location off I-5. In-store hours are Monday through Saturday, 10am-6pm (Pacific). For online help, customer service is available by phone, text, email, and live chat during those same hours. They even advertise a personal touch: "Call Kathleen" if you need help choosing a bike.

Reputation is decent overall

Bicycle Warehouse has a "B-" rating from the BBB due to one complaint they didn't respond to, but nothing that seems like an ongoing concern. On Trustpilot, they hold a 3.5-star average from just over a dozen reviews. Customers frequently praise the communication and delivery on bike parts but warn that buying full bikes can mean longer shipping times than expected. The site talks about "thousands of 5-star reviews from happy riders," but we didn't find evidence of that - still, the general consensus is that people who shop here tend to be satisfied.

Good enough for a bike parts store

Bicycle Warehouse does a lot right, from its long history to free shipping and an industry-standard return policy. The inventory is solid in most categories, but not exceptional across the board, and the reputation is good but not stellar. It's a middle-of-the-pack option in our rankings: worth considering, but we recommend checking higher-rated bike shops first and then circling (or cycling?) back to Bicycle Warehouse for comparison.

On the Bicycle Warehouse website

Universal Cycles is a long-standing name in the bike parts world, with a flagship 19,000-square-foot retail location in Beaverton, Oregon, and a huge online catalog of over 12,000 products and accessories. At first glance, the scale is impressive, but once you start trying to shop here, the cracks show quickly. From a clunky website to a return policy that feels overly strict, Universal Cycles doesn't hold up well against its top rivals.

Decent selection, subpar online shopping experience

Universal Cycles carries plenty of bike parts, but shopping for them isn't as smooth as it should be. The way their website is set up makes it hard to compare brands and prices in the size or style you want. For example:

• Tubes: There were over 600 options in the general "Tubes" and related products category, but you'll have a hard time comparison shopping (if you want to see what Beady and Michelin have to offer in the needed size, you'll have to scroll back and forth). Prices on the size we used as a sample ranged from $5.99 for Teravail/Q Tubes to $37.90 for Tubolito's S-Tubo.
• Saddles: You'll experience the same irritation when trying to shop for saddles. There are over 400 products in that category, including rain covers and saddle dressing, that you'll have to sift through - and the website makes it more challenging than most. Still, we found options like the Free Agent Race Seat for $19 and the MSW youth saddle for $20, as well as the Selle Italia SLR Boost 3D SF Carbon saddle for $479.90. (Missing were the Fizik Ventos we usually saw at Universal Cycles' rival stores).
• Derailleurs: Universal Cycles carries over 400 products in this category, which includes parts as well as the derailleurs themselves. On the low end, we spotted several Shimano closeout/overstock items priced at $14.99 to $19.99 (not bad for derailleurs with an MSRP over $100); on the high end, the shop carried several models by Shimano, CeramicSpeed, and Sram for $700+.

That kind of variety is good, but the awkward navigation makes it tough to compare everything quickly.

You're not going to love the shipping and returns here

Shipping costs aren't particularly competitive either. Universal Cycles charges $9.99 for ground delivery, with free shipping only available on orders over $150 - higher than most of its competitors. Returns are technically allowed within 30 days as long as items are new, unused, and uninstalled. But many customers say their refunds were denied because they didn't send products back in the exact box they were shipped in, even when the item itself was still factory-sealed. That's a stricter interpretation of "original packaging" than you'll find at most bike shops.

Customer support is during regular business hours (Pacific Time)

If you do want to reach customer service, Universal Cycles offers phone, email, text, and online support Monday through Friday from 10am to 7pm and Saturday from 10am to 6pm (Pacific Time). The retail store in Beaverton is also open during those same hours if you're local.

Reputation is "meh"

On paper, Universal Cycles looks strong, with an "A+" rating from the Better Business Bureau and no complaints filed there. But feedback elsewhere is more mixed. On Trustpilot, the 15 reviews are split evenly between glowing 5-star experiences and frustrated 1-star ones. Will you get "excellent service and fast responses" or "slow delivery, broken parts, no returns"? Those comments were left in reviews dated within a few days of each other.

Final take? Go with a higher-ranked rival instead

Universal Cycles may look like a strong contender with its enormous inventory and clean BBB record, but the reality is less impressive. Between its clunky online shopping experience, high shipping threshold, and strict return policy, it doesn't measure up to the best bike parts stores out there.

Bike Berry has made a name for itself as a go-to online retailer for electric bicycles and related parts. Founded in 2007, the company prides itself on factory-direct pricing, high-volume purchasing, and a focus on quality control. Its mission is clear: provide high-quality bicycles, e-bike kits, and motorized bike products at low prices. But does that translate into a solid shopping experience for both e-bike and traditional bike riders? Here's what we found.

Incentives and helpful guides

Bike Berry offers a few perks for new shoppers, including $10 off your first purchase when you join their VIP email list. They also provide helpful articles and guides - particularly for e-bike buyers - covering topics like engine kits, safety, and budget-friendly e-bike options. Unfortunately, these resources are largely absent for non-electric bike riders.

Limited selection of bike parts (electric or traditional)

We looked at common parts for both electric and traditional bicycles, since Bike Berry has a heavy focus on e-bikes but does carry non-electric bikes and parts. Here's what we found:

• Tubes: We had a hard time finding what Bike Berry carries in this category. Searching for "tubes" led us to a crazy range of products, from bicycle rim strips to rear gas tanks. We only spotted one actual tube: BBR Tuning's standard 26" inner tube for $5.99.
• Saddles: There were only 14 items in the Seats & Seat Posts category. If you're looking for an elite racing saddle or a big comfort upgrade, don't get your hopes up - because it's either not sold at all or it's out of stock (there were only 2 in-stock saddles at the time of our review).
• Derailleurs: Forget it. Even searching for the term "derailleur" only took us to full bikes for purchase.

Pricing claims fall short

Bike Berry promotes a "best price guarantee," but it's not a true guarantee. While the company monitors its prices and promises to try to match competitors, this is contingent on total costs including shipping, taxes, and order processing time. In practice, there's no binding commitment, and customers may not get the lowest price even if they find one elsewhere. The one upside is that you'll get free shipping on orders over $99.

Customer support is available - sometimes

Bike Berry emphasizes its highly trained customer care team and lifetime technical support for products. Support is available via phone, live chat, or YouTube guidance. While this hands-on approach sounds reassuring, many of the online reviews suggest mixed experiences in practice.

Reputation is wildly inconsistent

The company's BBB rating is an "F" due to unaddressed complaints, and Trustpilot averages 3.0 stars with multiple recent complaints about missing orders, delayed shipping, and issues with returns. And, Sitejabber shows a 2.4-star average. On the other hand, reviews verified through the site itself and via Reviews.io average 4.6 stars across 400+ reviews. This enormous disparity leaves us wondering what you might get if you shop here: you could have an excellent experience or a frustrating one.

Final take? Approach with caution

Bike Berry's strength lies in its e-bike focus, factory-direct pricing, and educational resources for electric bikes. But the sparse selection of traditional bike parts, inconsistent customer experiences, and questionable pricing guarantees make it a risky choice overall. Between the limited inventory and the extremely variable reviews, we've downgraded Bike Berry in our ratings. They're worth visiting only if you're specifically looking for e-bikes and are willing to take a chance on this retailer's hot-and-cold customer service.
