    2 Mode Controller

    "8 ) If instead I'm cruising down the same road at the same 20mph with my 33 amp-hour 80 volt pack, that bike calculator, and my on-board ammeter, both tell me I need to suck from my pack a steady 5 amps to maintain this 20mph. " You either have a magic motor or a magic controller. If your...

    RC controller on an E-bike

    Jay Here are some old posts that give some details. http://tech.groups.yahoo.com/group/power-assist/message/24972 Old batteries suck. I doubt it will go over 30 now. I tested it to 15 miles before the batteries got a little wimpy. I have moved on to Mopeds now for more speed and range...
