It's no wonder this friendly, helpful, and affordable shop has won this category for multiple years, now. There is much on offer here, no matter your budget. Unlike a lot of bicycle stores, they offer a variety of stationary exercise bicycles, as well as the regular transportation kind. They place a premium on education and fun, with classes that show you how to take apart and maintain your bike yourself, and regular rides as well.
