I don’t care who you are, you’re going to look silly riding running this thing. To make things worse, it isn’t a true bike, but rather a tricycle. The idea here is that there are no pedals, so this thing is fueled by running and a sore crotch.
When you pick up enough speed, hop on the foot holds and coast. The video below is pretty funny. What this thing amounts to is a bike sized frame being rammed up your crotch. I have no more words.
