Hey guys. I got the motorized bike out of the garage this weekend after sitting for several years. That caused me to start looking them up online again. I found that I can not find my engine for sale anywhere anymore. The 49cc hausheng 142f. Thats a shame because my transmission (the ez motorbike q-matic) had cost more than twice the amount the engine did lol. Everything still runs perfect on the bike, but Id like to pick up a replacement engine to just have on my shelf in case i ever need it

does anyone know where to find them?
 
Most of them are kits not the motor itself. Bikeberry has a kit but it's $300, pretty expensive. I think I saw some 5/8 straight shaft motors for sale by themselves. Ebay has huasheng knockoffs so it's a knockoff of a honda then a knockoff of a huasheng, but again they mostly come in a kit. What shaft does your transmission use? 49cc motorized bicycle kits - BBR Tuning 5G Pull Start Bicycle Engine Kit https://share.google/L25ZAHeLEyNGzuT2I
 
I'm guessing it's a 5/8 shaft. I saw an old post by Quenton Guenther saying it was 5/8 on those. For tapered shaft motors I've heard the 4g is a good one.
 
my engine has the tapered shaft, I think they all did. I had to buy an adapter from quenton that turned it in to a 5/8's keyed shaft

kings motor bikes is showing me its sold out, and the $300 kit at bikeberry is also sold out

You might have a rare or uncommon motor. Did the shaft stick out and have a taper or was it almost flush with the sidecover and had a clutch on it. You would have to extend the shaft itself which you pretty much have to do a crank swap for that. Here's a tapered shaft motor with clutch shoes on it.

Idk what works with the qmatic as I'm not too familiar with it all I know is there's a 15mm straight shaft shaft mostly ebay motors that use a bushing (I had that one). Then there's 5/8 straight shaft motors. Also short tapered shaft ones (for 4g or pocketbike style transmissions). I'm not sure if there's a longer tapered shaft one but it's sounding like that's what you have.
 
My ebay motor was fine except the fatal flaw of a plain brass bushing that loses its lubrication very easily (straight shaft 15mm). It was a belt drive. I'm assuming if you got a short tapered shaft ebay motor like in the picture above and a better transmission like a 4g it could last for years. There's another option you could get a 53cc 144f and they have them for sale on gru bee's website.
