The CarvX is the ultimate off-road bicycle for hardcore biking enthusiasts who like speed but not the spills during cross country rides. The bicycle’s four wheels reduce the loss of control. Despite its four wheels, riders still need to lean to steer. The recumbent design also means less energy is required to obtain a relatively high speed. The 14-speed bicycle frame is made of aluminium and four independent double wishbone suspensions & hydraulic disc brakes. GBO Design Engineering.
