Brakes
Brakes
Because children have smaller hands than adults, it's not always easy for them to reach the brake lever. This is why our engineers designed a brake lever that is closer to the handlebars and thus easier to hold. - Two V-Brake pads for effective braking.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.
