No matter how small or fast a bike folds, it needs to be a bike you want to ride. The BYB delivers with a frame engineered for stiffness, larger 20″ wheels, and performance components.

Small Fold, Slim Fit
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.
A New Way to Fold
Share Your Ride
The best things in life are shared, including your commuter bike. The BYB 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.
Theft Insurance
Locking your bike outside gets you looking out the window every five minutes just to check if it’s still there? The BYB folds so small that you can bring your bike indoors and stash it in the coat closet, behind the counter, or behind your desk.
Smaller Footprint
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.
Ready for Departure
Ever wished you could ride your own bike on vacation? With BYB, you can go from riding to packed bike in 60 seconds. The BYB makes air travel a whole lot simpler: just fold your bike and pop it into its own custom-designed AirPorter Slim suitcase—no disassembly required.
