  1. Can these be configured for lower speed, more torque, for hauling loads? And can it run in reverse? Looking to build powered bike cart, that can double as hand cart for loads.

  2. Hello,

    I am looking for 19 inch, it is to replace a 150cc (rated approx 5kw). I am looking for 60km Range minimum, can you advise on a recommended battery capacity (yes I know weight also plays a factor).

    • I built my battery pack myself, 16s(60v) 6p(1 KWh) and with my 26″ mountain bike setup I can get around 30km – 45km depending on weather and riding. the whole thing cost me $350 tho lol.

  3. Hello again,
    I have a few more questions:
    1. How many watts does it draw on 72v witj no load?
    2. What is the maximum and minimum and minimum watt draw?
    3. Does the controller have regerative braking?

  4. hello,
    I am looking for a brushless hub motor for an electric reverse trike build,
    it will need to be mounted to a 22 inch bike wheel, be powered by 48 volts, 60 – 70k/hr,
    and it needs plenty of torque for rough surfaces.
