Special B'Twin steel frame: lower in the middle to make it easy to get on and off. Children won't get stuck on their bike when playing.

A chainwheel anti-derailment device plus a low step-through frame that makes it easy to get on and off.

Tyres with an inner tube (inflated) and lugs. Real tyres to more easily get over obstacles (kerbs, etc.), and for better traction on regular terrain (paths, grass, etc.).Aluminium wheels.

B'Twin Stop Easy brakes. Rear hub brake and front cantilever brake. The brake levers are designed to suit children's small hands and require 30% less braking effort than traditional levers. We have chosen to use a rear hub brake for its effective and progressive braking. This type of brake requires less maintenance. On the front there are cantilever brakes, effective but not too powerful (reduces the risk of braking hard on front wheel and the rider falling head-first over the handlebar).
