3 POSITIONS: PATENTED HINGED SYSTEM
Our patented hinged system adjusts the frame height and geometry in 3 positions. It adapts to your child's size and skills - ensuring comfort, control and confidence at every stage.
EXTRA-LOW
SADDLE HEIGHT
Grow with your kid.
From just 280 mm for first steps
to
450mm for confident 4-year-old
PROGRESSIVE
STEERING GEOMETRY
Easy to ride from day one.
The front of the bike adjusts as your child grows, starting super stable and becoming more responsive as they learn to steer.
The head tube angle evolves from a slack 55° for stability to a steeper 64° for agility.
SAFE AND EASY BRAKING
We developed a safe and easy braking experience.
This powerful hydraulic brake system is carefully designed
and made for little hands. The custom lever is easy to
use for small hands with low strength. And the disc rotor
is specially design to keep the little fingers safe.
DRIVE BELT
NO GREASE, NO MESS
High-End Tech for the little riders.
The belt drive transmission system is cleaner, smoother
and lighter than a chain. It is maintenance free and we think
it is the best choice to build the best bike for your little rider.
MADE FOR LITTLE LEGS
TO SPIN SMOOTHLY
We designed our own crankset just for kids – short 80 mm crank arms and a narrow Q-factor* (120mm) match kids' body proportions for a smooth and natural pedal stroke. It is developed to fit narrow hips and short legs. Built in-house, unique to bonob®.
GEARING THAT
GROWS WITH THEM
Three rear sprockets to match your child’s progress:
19T for easy starts, 17T for growing strength,
and 15T to chase speed
(or maybe even Remco Evenepoel).

A slack head tube angle ensures excellent stability, helping your child feel confident and secure from day one.

The bonob® frame uses an avant-garde construction method inspired by aerospace engineering. Lightweight aluminum tubes are joined with fiber-reinforced polymer connectors, bonded using high-grade adhesive.
