The eRockit is a mixture between bike and electric motorcycle. You still use your legs to get it in motion but merely use your power as a trigger for the electric speed. It goes up to 80km/h so it can even be used on the autobahn. Moreover it looks fantastic and sounds like future (in this case the furture is noiseless). Of course, it’s a prototype and if you want to get one your own, it would be a toy worth 25000 EUR. But to be able to accelerate faster than a car on a traffic sign could be worth it.
