Concept Thunderbolt FS 20" Wheel Boys Bicycle
Another new junior bike from the clever bike geeks at Insync. This one is a cool customer, the Thunderbolt comes kitted with a front suspension fork designed to soften bumpy terrain. The bike comes equipped with Shimano Microshift gear shifters for rapid gear changing when faced with tough inclines. Designed for the boy bike rider who wants to try some offroad riding. It's fitted with powerful front and rear V-type brakes, alloy rims with mountain bike tyres that will also give a good ride on tarmac surfaces.
