Good bike for boys
听朋友推荐，果然没有失望，物有所值，真的不错。
车子出厂质量问题，走出店里链条频繁掉，却按照质保处理，什么逻辑
车的设计和质量都很棒，孩子骑得很开心。偶尔会发生4档降不到3档，需要降到2档再升档。
就是买的刹车片，工作人员没给装好，去换了后面，回来发现前面也有问题，中午太热懒得来回跑，晚上去店里找售后

Additional Product Information
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: an easier, safer system as the child's hands stay on the handlebars.This makes changing gears to match the terrain simple and easy!
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.
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 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 tyres
The tyres are designed for mountain biking. The lateral lugs provide good grip on turns. The tyres are made with SkinWall technology. This process makes it possible to reduce their weight, provide greater flexibility, therefore increasing their performance, grip and comfort.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.
Bike equipment
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 holder; - bike bags; - stabilisers
