Tern BYB S11

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.

The BYB delivers with a frame engineered for stiffness, larger 20" wheels, and performance components for mixed-mode commuters who do a stretch of their daily journey on a train or bus and demand convenience AND performance. It also has a low-step frame design and resizes in seconds—no tools required—to fit riders between 147 and 195 cm (4'10" – 6'5"), so you can share the bike with anyone in your family.
