Newbie looking for some help on new build

Welcome Rama!

If your bike does not have a rear suspension and a pretty open section for the engine, then it should not be a problem at all. Check out the mountain bike and road bike build section of the forums for tips.

If you do have a rear suspension, this will change the chain tension as the suspension compresses over bumps and you have to get creative with the chain tensioner to make it work.

As far as installing a motor with little experience with motors, that can be tricky. Some installations require quite a bit of modification to the mounts and bike, some bolt straight up. Some motors need to be torn down and cleaned up, ported, etc in order to run well, some do not. It would definitely help to have someone mechanically inclined to work with you.

If you could post a picture of the bike you are working with, that would help.

Good luck!

Welcome... With little or no experience, these Chinese 2 cycles are a great way to start. If you can follow instructions (instruction manual not the greatest, and that's stretching it), and have some experience using tools it just might be a go. My son had NO experience on any engines, I on the other hand have had too many years experience. He has learned most everything about them. These Chinese HT's are by far the easiest engine I've ever worked on. I suggest you read up on everything that you can find about them before you jump into building one. Heads up....to do one right, planing on a full day, and then some. With my experience, I took 2 (6 hr) days from start to riding. There is only one way to build them, shortcuts WILL get you in trouble....believe me. These engines won't just bolt up on a cruiser without mount mods. Here are some pictures of my second cruiser build, a $300.00 build.

I have compiled a paper, that will help you in your endeavor.

Best of luck should you tackle this project.

By the way $148.00 for a kit isn't too bad. I paid $107.00 (got lucky on a Ebay bid) for my 1st kit in 3/2009, my latest was $127.00 a year ago.

How hard will it be to mount it on a regular 26" mountain bike and still be able to use the pedals? Most bikes will have plenty of room to mount the engine, but very few will the peddles clear the exhaust pipe..this means that the pipe will need to be bent. Not a hard process.

And how hard is it to take one off and transfer it to another bike after it has already been installed? Be about the same as installing one on the first bike. Keep in mind that the frames will be different and the engine mounting won't be the same. Keep in mind that the optimum
"V" in the frame is 75 degrees.


What you see (above) is the instillation with factory mounts. Should (as others have) need to lower the engine, a custom rear mount can be made so the engine can sit lower in the frame.
