Small Fold, Slim Fit

The BYB isn’t just a folding bike—it’s a whole new way to fold a bike. Folds slim enough to fit conveniently into lockers, closets, or any narrow space.

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.

  • 30% smaller than traditional 20” folding bikes
  • Fits conveniently into lockers, closets, or any narrow space
  • Metro Transit Rack with built-in spinner wheels for easier trolleying
  • Fits riders from 147 to 195 cm (4’10” – 6’5”)
  • New TFL Joint with 3D interface, DeadBolt design and SpringLock technology
  • New 3D-forged Physis RF Handlepost
  • Kinetix Pro X wheels with paired spoke technology
  • 11-speed Shimano Ultegra, Shadow RD derailleur​
