Rock Machine Thunder 20 VB (red/black)
A light and fast 20“ bike with a rigid fork and V-brakes for fun riding in easier terrain. We fitted the bike with lightweight wheel builds that make pulling away easier and noticeably lighten the whole bike, which your little riders will appreciate on hills. We equipped the Thunder 20 with new MicroSHIFT shifting that is simple to operate and quality Schwalbe tyres with a reflective stripe so that the little ones are easier to see.
