Top speed is 60 MPH. The acceleration is unmatched. The rider is often challenged by cars for a race and never been beat. 15 horsepower max Briggs and Stratton motor running at 48V. In this video we compare it to a performance moped. ---

I should have shot video of my 48v Razor pocket bike. 😃 6 batteries and a curtis as well as a larger motor. It was TOO fast. ---

I would not trust that chain to be safe. I have had alot of bikes and motorcycles in my day. Look at the difference in size, a bike chain is so small and i have had them break just riding a mountain bike. Then look at a motorcycle chain , they are 5-8 times the size able to handle to tork and stretching. Just something to think about. Cool project but when that chain breaks I wouldn’t want to be on that thing. ---

A motorcycle is alot heavier with alot more power. If a crank arm on a bike is ~10" long and a rider is 170lbs that’s 141lb/ft of torque. Put that thru a 4" sprocket and you have 420lbs of pull on the chain. I’m pulling numbers out of the air and I don’t guarantee my math. =) Plus don’t have a crank to measure. Anyways, the chain on a bike is pretty damn strong. Quite capable of flipping the bike. What is the torque rating on those briggs motors? ---

I can see you losing a leg or your life if you’re not careful. I’d have a substantial guard fabricated to enclose the entire chain set. If is breaks it will rip your skin like paper and possibly throw you off on your head! BE CAREFUL! But I like the idea a lot!
