Cheap 😉 Btwin Rockrider ST500, Mountain Bike, 20″, Kids 3’11” To 4’5″ 😀

To ensure riders can easily overcome rough terrain, we’ve equipped this 20-inch MTB with a suspension fork. Easily overcome hilly paths with the 6 speeds.

We have designed this mountain bike for children ages 6 to 9 (3’11” – 4’5″ tall) who go mountain biking regularly.

Frame designed for mountain biking

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

Front suspension to cushion unpredictable terrain

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

Changing gear

This bike is equipped with a grip shifter to change between the 6 speeds: It’s safer and easier for children as they don’t need to let go of the handlebar to change gears. This makes changing gears to match the terrain simple and easy!

Controlled braking

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

A reinforced, ergonomic saddle

A saddle with a sporty design, designed with care to adapt to the morphology of children. It is equipped with a plastic cover at the back (a bumper) to protect from any impact.

Crankset

The new chainset has a 140 mm crank that is designed for a child’s leg length. This chainset allows you to start pedaling more easily. The crank is covered to prevent the child from coming into contact with the metal part. The double chain guard prevents the chain from derailing.

Riding position

When mountain biking, it is 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 needs for adjustments, so they can stay focused on the road!

20″ wheels and MTB SkinWall tires

The tires are designed for mountain biking. The lateral lugs provide good grip on turns. The tires are made with SkinWall technology. This process reduces their weight and makes them more flexible, which increases performance, grip and comfort. 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 MTB is equipped with a bell, wheel reflectors and platform pedals. The frame is also compatible with other B’Twin accessories: – front and rear mudguards – stand – bottle cage – saddle bag – stabilizers
