Fixing your own bike can seem like an unpleasant challenge; you have to acquire the right tools and replacement parts. And then there's the instructions to read before you even get started. Not at the UC Davis Bike Barn—here, savvy and friendly bicycle repair techs assess your job, steer you toward the right tools, sell you top-notch parts and then walk you through what you need to do to fix your bike. Or, if you'd rather not bother with all that, they'll fix it for you ($40 an hour labor).
The Bike Barn also offers rentals and holds huge periodic sales of refurbished bikes.
