If you think a bicycle is just a lower body workout, then the TwiCycle might change your mind. This bicycle lets you pedal, unusually enough, with your hands as well as your legs.
How does it work? The bicycle modifies the front section near the steering, adding a pedalling mechanism that can be worked with your hands.
TwiCycle’s makers is positioning it as a ‘gym on wheels’ as the bicycle’s design lets you utilise your whole body, working your biceps and back muscles as well.
