Time to start a new project for this bike. Here is the old version using a bafang hub motor and RC motor drivers http://endless-sphere.com/forums/viewtopic.php?f=6&t=6494 Now I am taking it into a different direction to really make it a Missouri Moped. The dropouts really don't lend to large hubmotors, so I will be doing a divorced driveline. Current Parts list: Fully built Santa Cruz Bullit Recumbence two stage RC drive Recumbence disc hub to chainring adapter HV 110 ESC Magura throttle Castle BEC pro MPI servo tester 17x2.5" Shinko dual sport tires (244 "golden boy" I think) 17x2.5" 32 hole Pro-Wheel rims 200mm 10ga spokes from Buchanan spoke Front qr20 marzocchi hub Rear 135mm Surly single speed (thread on freewheel style) To do: Finish welding up the drive mount drill out rear hub for large spokes lace up rear wheel figure out rear brakes- frame only allows 6" rotor and so far I can't get the caliper to clear sprocket without disc hitting frame or chain hitting tire. Get pedals working around drive unit (least important to me on this bike) A new rear sprocket adapter may be needed. I have a few ideas that could be done to get it all copacetic. Here is the drive mount. It simply bolts onto the swingarm. 1/8" rubber is used between frame and mount for cushion and void filling, as the tubes are not exactly round. As you can see here, the smaller motorcycle wheel allows the drive unit to tuck under the swingarm nicely. The ride will be lowered about three inches, so I may use shorter cranks. I plan to have about 15mph pedal power, just fast enough to get me home in emergency but not too hard to pedal with the stupidly meaty tires.
