Brake

The two V-Brakes are easy to operate thanks to their ergonomically adapted brake levers with reach adjustability. The levers require only little strength to bring the bike to a safe halt.

woom crank

The crank length and distance between the pedals are ergonomically adapted to fit children’s bodies. This results in an optimum stance and very natural movements. And thanks to the chain guard ring those days of getting your trouser leg caught are over!

woom frame

The superlight aluminium frame is the heart of the bike and ensures a fun and safe riding experience. Its cleverly designed age-specific geometry offers good control over the bike and gives young riders maximum safety while exploring new horizons.

Twist shifter

The easy-to-operate SRAM twist shifter enables riders to shift intuitively through the eight gears with minimal hand strength required.
