Hey I came across this forum and I had to join, i'm really excited about the re-build of my trike. Currently is is inoperable, the engine is shot, but starting in January I'm going to get working on it, hopefully it will be ready for the spring. Anyway, the bike i got is an old Industrial Trike (called the Mover apparently) that was sitting out at my grandpa's farm. Got a chainsaw from my friend and we rigged this beauty up. lol (see attachments) But i put bout 75km on the chainsaw and it bit the dust. Chainsaws don't like being operated at close to WOT for several minutes at a time. Also the gearing needed to get them to a reasonable RPM is ridiculous, my setup is a 35:1 ratio. So not comes the build, I purchased a chinese 50cc dirt bike for cheap (actually 48cc). I am going to throw that engine on, and this thing should go pretty good. Also I am going to upgrade the brakes and add a large container on the back for some functionality. Photo updates to come this winter when i start working on it.
