Knobby tyres with inner tubes (inflatable) - Real tyres for getting over obstacles (kerbs, etc.), and for better grip on regular terrain (paths, grass, etc.).

B'TWIN STOP EASY brakes. Drum brake at the rear and cantilever at the front - The brake levers are designed for children's small hands and require 30% less braking effort than traditional levers. We use a drum brake in the rear to provide effective yet progressive braking. This type of brake requires less maintenance. On the front are cantilever callipers, which are efficient but not too strong (limits the risk of the wheel blocking and the rider falling head-first over the handlebars).

Special built-in B'TWIN guard with patterns inlaid into the plastic. We created this chainguard to fully cover the mechanical drive train parts (crank, chain, freewheel, etc.), to reduce the risk of pinching (of small fingers) or catching (of laces), and to keep clothes clean.

Fully equipped for cycling on public roads (front and rear battery-powered light, bell). This bike can be fitted with 16" B'TWIN stabilisers and the B'TWIN training bar in seconds without tools (stabilisers and training bar sold separately), so that the child can gradually learn to ride on two wheels.
