You never know what you'll find at the back of this thrift store on Washington Avenue in the heart of South Beach. One day it's a well-worn 24-inch Huffy, the next it's a vintage model so solid it looks like it came straight from the set of The Bicycle Thief, complete with leather satchel under the seat. And the store's resident mechanic tweaks each bike to make sure tires, brakes, and gears all run just so. From classic Schwinns to road bikes to balloon tire beach cruisers, the stock is varied but never large (only a few on hand at a time); if you pass on a bike today it won't be there tomorrow.
