Hey Brian..........just got through reading the whole build thread.
Gotta say you done a lot with your disabilty do deal with.Kudos
Just can't figure out how you jam with one arm

Remember seeing Stevie Ray Vaughn playing with his teeth,I think he learned it from his mentor Jimi.
Got the OCC a 2005 model and it came with back and front brakes with no front fender.Black with red flames.Thought I would mention since some where back in your thread you mentioned OCC's did not come with front brakes.Odd year or could be an XL? How do you tell an XL from regular OCC's?
So I guess that the rear wheel is not suitable for hub motor,might as well sell it on Ebay rim,tire,and brake and get what one can?

What about the front?
Do you recall the the distance between your trailing arms in mm's on your OCC's,is it the same as the "Spoiler"? Do you or anyone know if there is ability to squeeze or stretch the arms,and by how much? Haven't had chance to muck with the bike yet as I am still very sore from the accident.
I'm not keen on the idea of a front wheel drive at all.I think it could be dangerous with this bike.
Found another OCC for $40 with single rear brake,front fender and excellent condition seat and wheels.Had been painted though.Figured it would excellent parts bike or a guinea pig for frame mods in case something goes wrong.Haven't picked it up yet as I need someone else to drive because of my injuries.
I was thinking of using 407/4011 on the rear with a 3p3t switch or 3p2t if I can't find one mounted like a two speed shifter.Can get 12v 80A 3p2t for sure for $20.That would be good for 48v 20A I believe.Should make 20mph,oh no?
