the hard part will be fitting an engine into the smaller triangle
you will most likely have to fab a new intake and maybe mounts
might also need one of the slanted plug engines as well

how about using a BMX cruiser, 24 inch tires?
Yeah, I know space may be an issue so I think I will buy an engine before I buy the bike though... Only thing that sucks is I can find a nice cheap bike for the project quicker than I can afford the engine. Oh well, such is life. Just thought I'd check.

Im building one atm. Have had to cut the entire downtube out and remake it so it has a 45 degree bend for clearence. As there was no way an engine was going to fit before.
Using a pocketbike engine with one of the dirt bike gearboxes to bring the drive further toward the centre of the engine. With it mounted up high the peddles only just touch so I am probly just going to shorten each side just enough. Dont realy intend on using them anyway theyre just for legality.
***Forgot to say that its a 20" Mongoose BMX***

I saw a kid on here who said he was 15 years old... can't remember his name, but he claimed he built multiple 20" lowriders (remeber the ones with bent forks). He definitely used a 49cc 2-stroke or less, maybe.... Don't some smaller frame-mounts exist? Seems like I've seen one or two places before, but I sure don't know where.
