Tern BYB P8 FOLDING BIKE

Cars, buses, trains. Shops, escalators, elevators. Lockers, cabinets, checked-in luggage. The BYB lets you bring you bike just about everywhere.

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.

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 to Roll

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.

A Bigger Ride

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.

Mix It Up

The BYB is designed for mixed-mode commuters who do a stretch of their daily journey on a train or bus, or might grab a taxi home on a rainy day. Folded, the BYB fits anywhere so all your transport options are always open.

Bring Your Stuff

A bike designed for commuting should let you bring your stuff, whether that's a change of clothes, workout gear, or your laptop bag. Add panniers, bags, racks, and baskets from Ortlieb and KlickFix to customize your ride.
