AGV Pista GP R Soleluna 2016 Pinlock MS
************************************** Transmission: Choice 1: motor directly drives large gear (Extron) attached to rear hub cassette (right side) via White Industries Eno hub Pro: simple, fast to build, Extron gears are cheap, allowing easy customization of ratio, allows use of Dual Drive hub Con: motor is restricted in placement somewhat, dual drive hub is very expensive Choice 2: single stage reduction similar to Matt’s, driving large gear (left side) Pro: flexible, cool factor is very high, motor can be placed pretty much anywhere, easy to fit slipper clutch, will educate me greatly in the building, single speed on motor side Con: time consuming to build, more variables to deal with, mechanical complexity may be more than I can handle Choice 3: single stage reduction driving a sturmey Archer 3 speed hub mounted as a jackshaft which then feeds power down to large gear on wheel Pro: gets me multi-speed on motor side, SA hubs are dead cheap Con: will SA hub tolerate RPM and Torque
