Sizing Guide

BYB S11

BRING YOUR BIKE
The BYB isn't just a folding bike—it's a whole new way to fold a bike. It's 30% smaller than traditional 20" folding bikes, and folds small and slim enough to fit conveniently into lockers, closets, or any narrow space. When folded, the BYB has one of the smallest footprints of any folding bike. That means a much easier time maneuvering it onto crowded trains and buses or when navigating through busy subway stations. Ever tried to ride on public transport with a folding bike and felt like you needed an extra pair of hands? The BYB stands on its rack, and its built-in spinner wheels let you trolley the bike with one hand while the other holds your coffee.
