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.
Apparently a limited amount of the bicycles will be made available in summer to early backers, as there will be a crowdfunding campaign on. Early backers will of course get a discount on the TwiCycles.
No pricing is available as yet, and if you want to get news on when the campaign is happening, you'll need to sign up to an email newsletter.
