Drivetrain

Mid-rise stem and handlebars.

Comfortable, reinforced (plastic shell) saddle. Fast, tool-free saddle adjustment. B'Twin selected this reinforced saddle for its tried-and-tested resistance (should the bike fall over, for instance).

Handlebars/stem/steering

Very reliable double brake Brakes. 
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.

Brakes

A sporty saddle specially designed for kids. Equipped with a plastic cover at the back (a bumper) to protect from impacts.

Reinforced, ergonomic saddle

The chainset has a 140 mm (5.5") crank 36t that is designed for a child's leg length. This chainset lets you start pedalling more easily. The crank is covered to prevent kids from coming into contact with the metal parts.

Crankset

When mountain biking, it’s important to control your path. To make it easier for children to learn, our engineers installed a handlebar and stem that are combined into a single steering block. This eliminates the need for adjustments so they can keep their eyes on the trail!

Riding position

The 20 x 1.95 tires are designed for mountain biking. The side lugs provide good traction for cornering. The recommended tire pressure is indicated on the side of the tire (2 to 3.5 bars). 20" inner tube and 1 4/5" to 2 1/5" (47 to 56 mm) Schrader valve.
