Well, I haven't ridden my new e-bike yet...but I'm sure it will be great, and I love the family-run business and how everyone knows me in there and takes care of me and my bike(s). Thanks, Becky, Mike, and Kevin!

Everyone at this shop is super friendly, helpful and knowledgeable. They also were able to answer all my questions (and I had a lot) to help me order the perfect bike for me. They have a big inventory as well with all kinds of bikes including many high end bikes. I highly recommend Chain Reaction Bicycles in Redwood City!!

Super friendly, helpful and very knowledgeable owners. This is a family-owned and run business that my husband and I have been coming to for years.
I can't speak highly enough about this wonderful honest bike shop. They also sell my favorite bikes -- TREK.
No matter if you are buying a lower priced good quality bike or a high-end racing/timetrial bike, you cannot go wrong by buying from this bike shop.
They have lots of bikes to choose from, bike clothing, biking tools and supplies and are a full-service repair shop. They can do it all.
Mike Jacoubowsky (owner) and his brother own the shop and Mike's wife, daughter and son also work in the store. Great People. Great Experience everytime we go to their shop.
Folks: If you are a first time bike purchaser, please do yourself a favor and not buy a cheap bike over the Internet that you have to try to put together yourself. Cheap bikes are made from cheap parts that don't last and fall apart. A lot of bike shops will also not do maintenance on a cheap/no name bike. There is always a good aftermarket for when you want to sell a good quality/brand name bike if/when you want to upgrade or purchase another bike.
Service is top notch. I really trust the folks there. Some items out of my size, but was happy with what I could purchase
Great service!
I love the family oriented atmosphere. Everyone in the shop is genuinely there to help you, and are very knowledgeable on their craft. They response is timely, friendly and up front.
Professional, high quality, personable and very nice
Efficient bike repairs. Staff answer my mechanical questions with patience.
Incredibly helpful, friendly, and knowledgeable employees. They helped me pick out a bike, then replace my back tire tube a few months later, after I forget to air up frequently and caused a flat!
Fast courteous service....
Ordered the shifters for my bike and they came as promised. The staff
was helpful.
Installed the part and I am back to riding!
Excellent and responsive service and products.

Everyone at Chain Reaction is very friendly and knowledgeable; they are willing to go the extra mile in order to help their customers. A great example of this is the following; I lost the charger for my E-bike and the owner (Mike) let me borrow a charger while I waited for a new one that they ordered for me. That kind of customer friendly service is rare and greatly appreciated!
