I have an AC4-4002 6.7 Inch motor from a Tropica that I'm putting in my new bike (see the photo album on the site for construction pix) and it's time to choose gearing.
Does anyone know how many RPM these can safely take at 72v? -- The Electric Motorcycle Portal http://www.electricmotorcycles.net/ Electric Motorcycle Listserv http://www.electricmotorcycles.net/listserv
