still trying, Thanks for this link. It is just what I was looking for. You are right that it would be easier to convert a bike, but there are regulatory stipulations. I have to have this considered a "Mobility Vehicle" and thus it must be electric and conform to certain dimensions. It will end up being about the size of a mini bike with a very short wheelbase. Still haven't gotten the regulatory dimensions. Ive built a mobility trike/ chopper before that worked well, but was a bit too wide. I'll have a sprung seat for the bums sake. The information you gave will make it easy for me to get started. Thanks

I hope I have not irritated anyone with this title. Allow me to explain. I was a trials competitor many years ago (1972-1980) and had many good bikes, mainly Montesa. I am also a metal fabricator and engineer. I am also legally blind. Because I can not longer drive, I get around on foot and that is a drag. So, finding myself with two 1000 watt electric wheel motors, a pile of Lithium batteries and some time on my hands, I thought to build some electric transportation. Since much of my area is over rough patches (like going over RR tracks at non-crossing locals) and my eye sight being limited, I thought the best "bike" would be a trials type bike. I would like to build it as a rigid to simplify frame geometry. So I wanted to ask this experienced group to give me some numbers that would normally be used on Classic Rigid trials bikes. Like Wheelbase, fork angle, trail, etc. I am building the frame from scratch using odd bits and some old race car tubing. It will have 19 wheels (110/80 -19 tires) at both ends as it will be two wheel drive. I know it sounds very strange and I am definitely not going to try to ride any events. I just want to have a reliable method to get around and kind-of re-live the days of plonking through the woods. I will never forget the water and mud I used to navigate with my old Cota 348. It was a very special time. Thanks
