Just bought 4 stroke Chinese bicycle engine frame mounting kit

geeksquid · #1 02-14-2008, 05:50 AM

Well, it took 10 days but finally got it. Bought it from revolutioncycles.us. When I opened the box, I knew I was in for some problems. The bolts, nuts and washers had bounced loose in the box for 1000 miles. They weren't even in a plastic bag. First thing I noticed was the motor mount was not adjustable as advertised. It's 2 inches too short for my new Schwinn cruiser. Can't go any further without this. Next, I find the sprocket kit only has 2 half moon clips when there should be 3. And one of the round rubber spacers had 2 big chunks gone out of it. Also, 2 of the bolts to mount the engine to the mount were missing. The petcock is an extremely tight fit into the gas tank. So tight I thought the threads didn't match. Well, I spent $285 on this kit and it's totally unusable. I contacted the dealer and told him about the missing parts. He gave me a rambling one liner reply about the Chinese and that was it. Also, there was no assembly or parts manual of any kind, and I wasn't sure what all of the parts were for. There's a fiber washer I don't know what's for. Asked the dealer, no answer. There's a small thin flimsy metal piece with 2 holes. Asked the dealer, no answer. Asked if he would send the right motor mount, no answer. Asked if he would send the rest of the spoke mounting kit. no answer. Since Don Grube's name is all over this stuff, I checked his site and see all the parts he wholesales. He's obviously the grandaddy of the Chinese bike engine thing in the U.S. Sent him an email and asked if he could give me the name of a dealer where I could get the adjustable motor mount. He won't help. He rambled a bit about how the dealer I bought from is illegally importing 2 cycles into the U.S. and told me to report him to EPA. Yep, I'm sure I'd get my missing parts if I did that, yeah right. Bottom line, my dealer isn't going to make anything right and stopped answer my mails. Don Grube refused to offer any free assistance. I have a box of parts here that cost me $285 and I can't use it. Won't even tell me where to buy a mount. I get the impression that the bike engine "industry" is pretty much an overall shady operation, run by a bunch of thugs. I spent every last dollar I could muster up in the hopes of finally having some transportation. And now I'm also stuck with a new Schwinn that cost me $150 and will have to return it for a refund if possible. An entirely new problem. Gotta love it!

Sorry to hear of your problems. If you were to post pictures with specific questions we may be able to walk you through the instalation process. These engines are designed to fit a diamond frame much like the 3-speeds of yester-year, I have never heard of an ajustable engine mount that came with these kits. Most of us hear have had to kustom fit our engines to our individual bikes. As for identifying the other parts you mentioned, I'm not going to try to answer without pictures. I hope we can help you and please don't be discouraged, the first build is always the hard one...Kelly

you got that right kelly. my first 2 hour motorized bicycle build took like 200 hours lol but it was worth every minute i put into it. it is frustrating but I promise it will be worth every minute

When norman get's back message him. He will be able to tell you what to substitute to make it work most likely. If you have a digital camera send picks on problem at a time and we can try to find solutions for you. And my first build took weeks. And i still got it wrong lol..

Since you don't have your directions let me suggest that the first thing I would do would be to work out the mounting problems.

If you are sitting at the bike with the handle bars on your left side, You want to mount your engine with the clutch lever on your side of the bike. That is also where your chain fits into the motor though you wont have it on yet.

Step one should probably to loosely hook the engine to the seat post. If you do that tell us, will the front mount reach your down rod on the handlebar side. if not how far out is it.. and if so can you fit the mount around the drop rod or is the rod too big for the mounting.

By the way my engine was supposed to have the big frame adapter but it didn't. Fortunately I had a bike with small tubes. I still toyed with mounting it to a larger bike frame. It only took me two days to decide which bike and how to attach the engine.

Yes I agree the whole supplier end is Chinese cheese. I doubt you'll get satisfaction, but I'll bet you get threats. I think at this point you should make a go of it.

For instructions, you just might find them on the web. I found a mess of two stroke versions on the web, someone must have scanned the fourstroke WI's as well.

I'm not at home right now to give you links, but there are dudes out there that sell just about every part.

Please explain this adustable engine mount. I've never seen it....

You're talking about the Chinese 2 stroke kits. Mine is a 4 stroke kit. I'm going to have to get the adjustable motor mount, no way around it. My Schwinn does have big tubes, especially the front one. But all the gallery pics I've seen of my kit on various bikes shows the adjustable mount. I was just sent the wrong motor mount. I'm working on getting the right one but I envision it costing me some bucks and many headaches dealing with shady suppliers. Already been thru **** with it. Can't proceed at all without that mount and the rest of the parts for the sprocket that are missing. It's not that I don't know how to install the stuff, it's a matter of not getting all the parts.
Here's my bike:

Here's a kit that looks like what I have except my motor mount doesn't have that adjustable piece to it with the ends that fit the curvature of the frame. What I got was the darker chrome piece you see in the middle of it all:
