What I am looking for precisely is a very small engine, that will "assist" me on very long, flat, stretches.
Installing a 30cc'ish trimmer motor with proper gearing - motor 10T to wheel 50T+
Is it possible doing a good warm sunday cruising speed (25-30kph/16-19mph) on flat ground and 370lbs total weight.
I know I've seen gears from industrial supply up to 90T, also electric mid drive stores have lots of gearing choices, go karts etc, so I dont think gearing would be an issue. How easy they are to adaptable to the spokes on the wheel, or disc mount, is solvable.
Perhaps a speed bump I would run into is how to get a suitable gear sprocket onto the 30cc trimmer motor.
