I have a single speed I want to use for my next build. But it was not also a single speed. It is an '80s or '90s model Trek Antelope 800, with a very high quality steel frame and Araya aluminum rims with large flanged hubs, stainless steel spokes, etc. I removed both derailleurs, and the larger front chainring. I have the chain on the smaller front chainring,, and on the middle rear sprocket. I got lucky, and got the chain adjusted right in that position by removing links. It doesn't always work that way. The chain will be way to tight or way to loose. This is a very low geared bike, capable of climbing hills, and cruising on level roads, though at very low speeds unless you can really spin it. I put a much more comfortable seat and upright handlebars on it. My original intention was to use this bike as a "canal bank cruiser" We have a canal nearby, over 20 miles long, with a dirt road on both sides, where motor vehicles are prohibited. So it makes a nice place to ride a bike. Unfortunately my knees are slowly getting worse, so I built a Huffy Cranbrook with a Staton friction drive and RS engine. It still works fine, but I now want to build a MB out of my Trek, with either a Chinese engine kit, or a 4 stroke engine kit The main issue with these kits is the chain tensioner/idler. I know that from experience, having destroyed a rear wheel and almost crashed.
I also came up with the idea of welding a piece of flat steel stock from the seat stay to the chain stay, and putting some kind of super heavy duty roller or rubbing block on it. I believe I've already seen something like that on this forum. It would have to be strong enough to hold the chain in place no matter what.
