B'TWIN Stop Easy brakes. Rear hub brake and front cantilever brake. The brakes, specially designed for children's small hands, require 30% less braking effort than traditional levers.

On the front there are cantilever brakes, which are efficient but not too strong (limits the risk of the wheel blocking and the rider falling head-first over the handlebars)
