Based on a device originally built to take on the Automotive X-Prize challenge back in 2010, the Twike 5 is an ingenious road vehicle that allows commuters to steal a bit of fitness work as they sit in traffic. You sit in the twin-seat, waterproof, lockable cabin and pedal away like you’re on an exercise bike – and you are, really. The pedals connect to a generator that tops up the battery on this nifty little jigger as you drive along.

Steering is accomplished through a pair of push/pull levers instead of a steering wheel you might bang your knees on. Oh, and there’s pedals for the passenger too, so you can both work up a sweat…

Twike says its vehicles can be driven on a range of different car and motorcycle licenses in the EU, depending on its power output.
