This bike was made by my team.
I am an inventor of the combined drive bicycle and i invented it three years ago.
At the first made bike, i have confirmed that human can drive bike with hands and feet, however the critical parts of the bike were not precise enough, so that i designed the second trial bike with my team members.
This video is about the first complete hand&foot drive bike in the world.
Compare with any other hand and foot bike that inventors tried to accomplish the task.
Thank you and enjoy it
