I went with a front 5303 mainly becuase it was easyer.To mount the hub on the big fat rear rim I think you need to drill the spoke holes bigger with custum size spokes. I have seen it done, I have some pictures of rear wheel mounted hub motors. I had a 48 volt(overvolted) wilderness motor before with no torqe arm and it was fine. One of the things I didnt finish on the upgraded 5303 was the tourqe arms. It was working great for me becuase I knew not to slam on the throtle. Long story short, I was finishing up my bike before I had surgery and took it to the bike shop for some extra help with a few odds and ends and to install the front disk brake. They told me it would take a few days. I went back 2 days later cuz I was going in for surgrery early. I wanted to ride my new dream electric bike that I had finished building, becuase I would be recovering for awhile. I went back, to find that all the kids that worked in the shop loved my bike and couldnt belive how fast it went. They didnt have time to fix the brakes but the had time to take turns in the parking lot riding my bike. So I take it home and the baterys are almost dead, and the front drop outs are rounded out from them juicen the throttle with no tourqe arms. A day or 2 later my daugter and I went to take one more big rode trip on the bike, and it never worked agian. I bought a new controller because I thought I fried it, but no luck. Its Probly wires in the hub shorted or something. Anyways thats my sad story to my sleeping spoiler as she lays resting. A shop in Newport beach where I bought the bike at help install the 2nd seat. My daughter was 3 when she rode on the back and the bike was fine, we zoomed around town like nothen. Shes now 5, Im not sure how it would hold up now. The seat is mounted on a rack, but the rack is mounted to the frame were the rear fender bolts on. It would be stronger to mount something to the axle in like a big U around the fender. When I had 48 volts this thing was fun now i stuffed in the box 6 heavy sla batterys to make 72v. Now with all these big hunkn batterys It went 40 mph. With the springer front end and the springs on my seat it rides so smooth. I cant remember the range, but it would take me and my daughter any where in my town and back so it was ok. Thank you for all the compliments on my bike! There were alot of pianfull hours into it(right before neck surgery). Luckly I had some help. My brothers freind has a race truck and built the battery box and threw a bunch of my parts in with is truck parts to get them powder coated black. Someday I would like to finish it. Its still needs, lipos, blinkers, talillights hooked up, and of course tourqe arms. Well I hope that answers a few of your questions, sorry for the rant on my sob story. Here is a pic in its current state in the garage.
