Please select options


For little cruisers looking to pedal their way forward…and coaster brakes to make them stop! Sure, we had grunge in the 90's, but it was never this much fun. Channel your little rocker's energy into two wheels and get them gunning for a different kind of stage from an early age with a single-speed bike built just for riders who are growing up through the ranks. The LegitFit system gives them better positioning, easier pedaling, and a faster start to your next ride.
