Hi everyone, I've wanted to put together (and ride) a motorized bike since I was 11... about 16 years ago. Well, I've finally gotten to the point where I can. I currently have and ride a 2007 KHS Urban Xpress, and I'd like to motorize it, but am not sure as to what, if any motor kit will properly fit it. I don't want to cannibalize the bike as it is currently my main mode of transportation. I'm not sure as to the size of the frame, but can easily measure whatever dimension is necessary. If anyone has an ideas on what kit would work, what I should measure, etc. please let me know. Can anyone help? Thanks in advance!
