Build a fast e-bike/moped with this kit.

This is the correct dropout for the S-2, ZX and R/RX frames. A 72 volt battery is required to power this motor (choose 20 ah or 32 ah). Max speed?  (Reported from the field: 59+mph on a 20 x 4 fat tire bike.) 

Great install videos and info at Mr. Central Driver!

Finish your build like a pro with colored wire wrap! Professionally organize your wiring with a variety of colors.

Note 1: Obviously, this sort of modding to any stock bike will not only give you warp speed, but will warp your manufacturer's warranty.  That's a risk you are accepting. Be smart: use a full face helmet and maybe even a jacket with some armor, and gloves - definitely gloves. Don't ride where you will annoy people or might cause an accident. Riding a bike frame at high speeds carries risk of bodily harm or death and you understand and are assuming that risk. Be safe and have fun!

Note 2: This is not "plug n play" modding. The slide-in axle tabs for the stock RX are too small to fit the axle on this motor and will require a machine shop to mill out a few millimeters all around to fit the new axle. On the RX, the large 72 Volt Battery required for this motor will not fit in the space below the top bar but can be mounted against the down tube. (It will fit okay on the S-2.) The controller that comes with this system also will need to be mounted either in the frame or under the seat. This is a fun project, but not a paint-by-the-numbers kit.
