Product Information

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.

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.

Pop, Cover, Roll

Most folding bike covers are either too complicated or too time-consuming to use several times a day. The BYB isn't just easy to fold and trolley, it's also extremely easy to cover—simply grab the PopCover and you're ready to go.

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.

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.

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.

Easy Storage

Small apartments and commuter bikes don't usually match. Great news! The slim, small BYB fits just about anywhere—behind doors, under desks, in your closet. In fact, the BYB is a perfect fit for standard cabinets so whether you've got one, or more, the BYB will occupy minimal space in your place.

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.
