My father built a prototype of such a device 20 years ago. He abandoned the project after trying the prototype, because it accelerated dramatically and he could not brake. He jumped sideways into the gutter and was really scared.
My personal opinion is that the bicycle is already invented and its excellent energy efficiency is hard to beat.

- hinkley 3y agoI know some people who tried.

- hinkley 3y agoThey were head over heels about it. Seriously though, if you don’t have your helmet adjusted about as far forward as it can comfortably go, there are a number of angles at which you can take a header where part of your face touches the ground. If you’re lucky nothing hits but helmet. Less lucky, a bit of road rash. Less lucky still, maybe some loose teeth. The higher speed collisions I heard about mostly involved back injuries, which is less fun than artificial teeth. Younger people try to face plant.
