They do have 2 stroke races, though I know little about them. I do know that there are guys out there doing hybrids with cylinders from Minarelli scooters pushing stupid amounts of power though. 10-15hp from a 70cc engine.

Then you have the speed demons who are just obsessed with going 60+mph on a bicycle. Heck, there is even a gentlemen who builds custom wheelsets just for motorized bikes with 11mm thick spokes, sealed roller bearing hubs with extra thick axles, and really beefy double walled rims.

The last time I looked into doing this for the fun of it, none of this stuff was even a thought. It blows my mind lol

Heck, even this phantom engine I bought has to make about 5-6hp and is very torquey. Watched a video of a guy that took a stock phantom, had an expansion chamber modified to fit it installed, put a 32 tooth sprocket on his bike and hit 52mph.
