BIKE BUG!
Reminds me of a "Bike Bug" engine I had back in 1986.

It was a little 2 stroke with a front wheel cog that powered a front bicycle wheel.

I drove the heck out of it, for 2 years straight...winter, spring, summer, and fall.

It was bullet proof, as long as the roads were dry.

Once wet, the cog would slip and lose friction with the bicycle tire.

There were French 1950s motors known as Bima that fitted upder the bottom bracket, and they had big drive rollers. I mentioned them on a FB page for mopeds, and a couple of owners say they have no wet drive prblems.
