Store the bike in a clean, dry place. Clean and grease the chain regularly. Pre-ride tips: inflate the tires to the pressure indicated on the sidewall.

Ease of use

Equipped with a grip shifter to easily change gears (6 speeds).

Brake control

The new Easy Brake levers are made for children’s small hands.

Efficiency

Suspension fork. Tires with side knobs.

Frame designed for mountain biking

Our engineers have designed a new sturdy steel frame. The frame’s rear chainstays are short so the bike is responsive and easy to handle.

Front suspension cushions bumps on unpredictable terrain.

Take on new challenging terrain (roots, stones, gravel, etc.) with the travel of the front suspension fork.

Shifting gears (6 speeds)

This bike is equipped with a grip shifter to change between the 6 speeds: an easier, safer system, as the child’s hands stay on the handlebars. This makes shifting gears to match the terrain simple and easy! 14/28 6-speed freewheel.

Controlled braking

Two V-brake pads for effective braking.These brakes are composed of calipers that exert more or less pressure on the rim to slow down or stop the rotation of the wheels.

Reinforced, ergonomic saddle

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

Crankset

The chainset has a 140 mm (5 1/2”) crank designed specifically for children’s leg lengths. This chainset lets you start pedalling more easily. The crank is covered to prevent kids from coming into contact with the metal parts. The double chain guard prevents the chain from derailing.

Riding position

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!

20” wheels and mountain bike tires

The tires are designed for mountain biking. The lateral lugs provide good grip on turns. The recommended tire pressure is indicated on the side of the tire (2 to 3.5 bars). 20” inner tube, 1.7” to 2.2” Schrader valve.

Bike accessories:

This mountain bike is equipped with a bell, lights, wheel reflectors, and platform pedals. The frame is also compatible with other Btwin accessories: - front and rear mudguards - stand - bottle cage - saddle bag - stabilisers:
