I'm still fixing some kinks but it seems to work well. got it up to about 25mph. I'm able to use the gears of the tag a long trailer. it will probably go faster. I get some wobble at higher speeds. thinking of some stabilizers. any ideas?
I do not have a pull start. I start the motor with the pedal. I have to take the derailleur side chain off every time I want to start it. It's not difficult and its effective.
Just poking around, getting ideas for my own little build, and wondered if this had a solution. I really like this idea. I have an idea to use a spring, to keep forcing the pusher to the ground. I'm guessing the pusher is getting "on plane" once you reach the 25mph speed. Even an air shock, from a scrap donor mtn bike, will work
I've actually got the pusher up to 35mph. I've since dismantled the project and put the motor on the a mountain bike. The problem is that the motor is not heavy enough and it will bounce all around. I don't think shock absorbers will help because of how light it is. It was fun idea.
I agree with chaput87, I believe that your center of gravity is too high. Really interesting build, I would try to place the engine down lower and drive the chain straight back to the crank sprocket.
