Velocharger - Get fit & charge your phone

Hello, My name is Kamil and I'm 13 year old. I got new good idea. New way of Playing on your phone and don't get fat. Basically it works like this. You Get on the "Velocharger" and sitting on it. Then you move pedals and it makes energy so your phone is charging. Sorry for bad grammar. I still learning. Thank you.

Regards, Kamil.
