The Rockrider ST 900 is the top specification mountain bike in BTwin’s 20″ wheel kids mountain bike range.
With a lightweight aluminium frame, front suspension, 6 speeds and grippy tyres this is a great value bike for introducing your child to the joys of mountain biking.
The bike is unusual in that it has a front disk brake and a rear V-brake. The disc brake will help give some additional stopping power in the wet, and the V-brake helps to keep the price down.
The brake levers are designed for small hands (and the saddle is moulded for little bottoms). It’s also supplied with a front and rear LED light.
