Ultra-Compact Folding Bike To Go
Wanna go everywhere with your bike, but held back by cumbersome logistics? Say hello to the BYB! This ultra-compact folding bike travels unassumingly small to fit whatever mode of transportation you choose, but delivers an impressively bigger ride. So Bring Your Bike, and answer wherever the paved road may call.

8-speed Shimano Alivio
Built-in spinner wheels
DoubleDeck Frame







⓵ TriFold Technology
TriFold technology is a patented new way to fold a bike small while delivering a quality ride.
⓶ Metro Transit Rack
Roll the BYB like a spinner suitcase and easily maneuver the folded bike in crowded rail or bus stations. The Metro Transit Rack carries up to 20 kg (44 lb) and allows the BYB to stand vertically. Equipped on the BYB S11 and BYB P8.
⓷ DoubleDeck Frame
The BYB inherits important technology—DoubleDeck frame design and the burly trapezoidal tubing—from the Tern GSD, ensuring extra stiffness and durability.
