TECHNICAL INFORMATIONS

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.

Why have we created a brake lever specifically for children?

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.

Single speed

With only one speed, the bike is simple and remains effective on flat terrain.

Controlled braking

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.

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 section on the rear (a bumper) to protect against any impacts.

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!

Crankset

The new chainset has a 140 mm crank that is designed for a child's leg length. This chainset allows you to start pedalling more easily.
The double chain guard prevents the chain from derailing.

20" wheels and MTB tyres

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

MTB fittings

This MTB is equipped with a bell, lighting, wheel reflectors and platform pedals.

The frame is also compatible with other B'Twin accessories:
- front and rear mudguards
- stand
- bottle cage
- saddle bag
- stabilisers: https://www.decathlon.co.uk/20-and-24-stabilisers-id_8550741.html

Ordered this bike online as an xmas present for my grandson. Travelled to the Oxford store expecting to pick up a box that i would assemble myself at home. I was very suprised when the staff member wheeled my bike out slready assembled. I was then advised on the merits of he 20inch frame, how to adjust everything, and offered to fit the mudguards i purchased in store. Was also given a full brief on the returns policy if i wasnt satisfied, and also the contact details for any problems. The bike was excellent. Under £100 but with all the quality and materials of a bike a lot more expensive. I cant fault the bike or the service at Decathlon. I would recommend the shop wholeheartedly. Made my xmas shopping a lot easier.

The bike sizing was exactly as listed, build quality was much better than expected for the price and very little to do in the means of assembly. Very pleased and will buy from Decathlon again.
