Chain drive does not have all the parts that a belt drive does. Be sure to know what you are buying before you place the bid. But the engines are wonderful, I'm thinking about putting one on the front tire too

Got the chain option. It works great! Just be ready to improvise on the motor support . I had to make a slit in to the verticle tube support of the bike because the motor wouldn’t slide in place . The spark plug was like an inch or two from clearance at the top. I recommend centering the plate and running the chain to make sure it’s straight so that you won’t have to make too many repeat red-adjustments. The grooves for the screws on the mountains plate might not coincide with the screw holes on the bottom of the motor after seating the mountains plate to the correct adjustment. I was only able to secure the motor with the front two screws because of this reason. The motor still holds but at some near future moment I’ll have to take the motor off and drill two pilot holes through the mounting plate in order to hold the motor to the plate with the 4 screws. It’ll be much better secured this way. Make sure your brakes work good cause if you’re coming down a slope fast you ll need to have solid brakes in place. You’ll prob reach 38-40 mph . Other than that really good buy and fun bike project . Pretty fun!
