Anyone use a pocket bike motor?

I've researched some of the cheap chinese pocket bike 49cc engines and they claim to put out about 3 hp at 11,000. I was wondering if anyone used a pocket bike motor, and how they performed.

The trick would be getting one up to 11k rpm. I have a junk pocket bike that I rescued from a dumpster and the chain it uses is tiny plus even on a bike that small the rear sprocket is almost as big as the rear tire. If I remember right the front sprocket only has about 6 teeth.

I've been tempted to go the other way and put a China Girl engine on the pocket bike. lol

I HAD a pocketbike for a while, but some ******bag stole it. It didn't even run.
I got to ride another one for a while that I fixed for a friend's kids. It was the little cheap one like from pep boys or something. It had a 12v "starter" that was more like an electric assist start and battery charger. It was about 40-50cc. It would move the bike from a dead stop but only really got going around 15-25mph. It used some crappy little skinny chain that I don't know of any other uses for. no hobby shops or mechanics, even tire shops, will touch these things. Someone gave me a free tire valve and a cola just to go away.

I was going to rack mount it to a bicycle like a BMX or old rigid 26" bike.

Glad to see someone has done it.

A engine mount to fit MB's is being auctioned. got one. well built and price was right. Shipping was high. Pocket engine for $75. Now to find a donar bike.My guess is it will need a jack shaft.
These motor bicycles are habit forming. Got to keep trying till its right.

Here's is the pocket bike motor someone would use if they wanted to build a 12hp water cooled race bicycle!
