Im thinking roller on the shaft yes. Make it interchangeable then i can adjust the size of the roller to get the speed I want. I think I can mount it to the bike the same as an electric. I saw a complete reconditioned weed eater for 50 bucks but I don't know what the cc's was i didn't know enough to get the model of the weed eater.

I have a bid on 31cc on ebay now I wish I hadn't bothered I could have just bought the one here. Anyway I'm going to check it out. I'm sure I'm going to have a lot of questions as I go along. So expect to hear from me as I go.
