Product description
The sophisticated Woom 4 OFF bike model is precisely adapted to the conditions of rough terrain and the needs of adventurous children. High-quality off-road tyres, hydraulic brakes and playful geometry create the perfect mix for exploring fun off-road flow.
The basis of all Woom models is a lightweight aluminum frame with geometry designed with the specific needs of small cyclists in mind. The Woom 4 OFF model is also built on a lightweight aluminum frame with more trail geometry and a more cushioned carbon fork for the best possible trail control, and solid axles have been added to increase the safety and strength of the bike.
The bike is equipped with powerful hydraulic brakes and Schwalbe tires that can handle even the most demanding terrain. The 9-speed Sram X5 derailleur provides easy and smooth shifting.
Woom 4 OFF places great emphasis on the contact point between the child and the bike, the grips, saddle and pedals are ergonomically adapted to the needs of a small cyclist.
Main advantages and parameters:
- High-quality aluminium frame with trail-ready geometry and a padded fork for best trail handling
