He was incredibly knowledgeable, patient, and genuinely cared about making sure we found the right fit. The kids' trade-in program was such a fantastic idea and made upgrading to a new bike so much easier. It's great to see a shop that encourages kids to grow with their bikes while also making cycling more accessible and sustainable for families. From the friendly service to the thoughtful programs, Alameda Bicycle truly sets the standard for what a local bike shop should be. We're so grateful for Draco's help and will definitely be coming back for our future bike needs. Highly recommend!

    Disappointing assembly quality and warranty service…read more I bought a new road bike with Shimano 105 from Alameda Bicycle, but the setup quality was very poor. Right at pickup, the hydraulic brakes felt spongy. The mechanic told me to just ride it out, but after 100 miles of riding, it hadn't improved. During those rides some issues were also revealed: the shifting was rough, the drivetrain was noisy due to poor alignment, and a twisted brake hose was rubbing and scratching the frame. I brought it back under their 90-day guarantee, but the shifting and noise came back worse, and the brakes weren't addressed at all. I eventually spent hours fixing everything myself after purchasing tools and watching countless guides on YouTube. Lots of bubbles came out when I bled the brakes. Now that I properly bled the brakes and adjusted the derailleurs, the bike works great. No thanks to Alameda Bicycle though. Very disappointing build and service for a brand-new purchase.

What stands out to me is there quality of bike services for repairs, customer service for shopping for a new bike, and bike maintenance. They also have a used bikes section (varying inventory) which is terrific for families with young kids that frequently need new bikes without breaking the parent's bank. On the flip side, for the more enthusiasts or adult bikers they have bikes that should satisfy their needs for sure. The staff is helpful and friendly which is something that's never present with online or big box shops so definitely consider this bike shop in the future.

    Short Story: The best bike shop in the Bay Area!…read more Long Story: I first came here in Aug 2024 to purchase a bike. They have a large selection of Giant brand bikes at all price ranges. James and his staff was very knowledgeable, courteous, and professional about everything. They really spend the time to answer your questions and not just to "sell you something." The process to buy a bike is that you go to the retailer website (for example, Giant) and order the bike yourself. You have the bike shipped to Centripedal and they will assemble it for you. Afterwards they will call you to come in for a fitting. Then after this you can take the bike home. You get one year of maintenance, parts, and labor for free. Afterwards, you then pay as needed. The turnaround time to get the bike was about a week and James was able to deliver it to me (after fitting) as my car couldn't fit the bike and I lived relatively close by. Verdict: I'm going back in the future!
