While bicycling can help work out your legs it doesn’t really do a whole lot for your arms or upper body. But the Raxibo Hand-Tret-Velo system looks to offer a full body workout. In addition to the traditional pedal driven drive train it offers an arm-powered one as well. Thus riders use both arms and legs.
It doesn’t look like the arm power actually gives any added speed – especially riders are more upright and less aerodynamic, but riding isn’t about speed alone. Sometimes – as the video shows – it is just about a solid workout. Video after the jump
