I got an old ProFlex 854 and was thinking about putting a HS 49cc on it. Kind of limited in California from what I've read here. I'm just worried about putting one on a bike that's 20+ years old. Holds up well, though. Really interested in motorizing a bike in general, though. The more I read threads here, the more I think it's a great choice. Should I find a new bike?

Also, where should I start looking for a kit? I was looking at King's rear kit for the HuaSheng 49cc, but I'm not sure where to start!! Quite a few sites to choose from. Pure noobie, forgive me :p

Ditto WightBoy's recommendations, have had good experiences with both of those company's many times. You should go with the proflex, they were pretty decent bikes as I remember them.

i dont see a problem with that as long as u do ur maintenence on the bike more regular that u normally would. I do the very same thing.
im running a 15-20yr old trek mtb. solid as a rock and havnt had issues with the bike itself at all. :D (knocks on wood)

hope u soon find the joys of the world of motorized bicycle :) brnot.shft.

You know your stuff. Didn't even know about EZ Motorbike till just a while ago. The 4G looked good, but the Q-Matic looks to be all the rage. Might be spending more money then I initially planned, but I wan't longevity :) Gotta spend to save, the way I see it.

Also, will rear suspension be a problem? It's apparently best to put the engine in the frame instead since it can cause it to be top heavy and the engine would have to draw the fuel upward.

Thanks a lot.

Yea. Would prefer full as long as long as it doesn't get in the way. I was doing some the measurements on the bike and don't think I can fit the HuaSheng in the frame without putting it in at an angle. Might have to consider looking for a new bike, or at least a frame.

yup, that's the one. I went down to single speed afterwards so I will either have to run a tensioner on the pedal side or a derailleur in the right position.

Excuse me, but what would be the reason for going down to a single speed? The engine is connected to a separate sprocket, so I assume it wouldn't matter, but any reason you can't hook it up to a set for different speeds so the engine doesn't work harder all on the same sprocket? It's on the opposite side so I figure it might be weird to do that or something.

I ordered some worksman wheels for durability as the Schwinn ones are nothing shy of junk IMO. The worksman wheels come standard with a coaster brake hub which is single speed. That's the only reason behind that.
