Hi everyone, have learned much from the forums from lurking, but it's time to seek some specific help.
I got a Heinzmann 36v 750w 30A hub motor from the local bike coop. I plan on lacing it to a 20 inch rim and using a Crust Clydesdale type fork to upgrade my food delivery bike and hopefully later use it with a larger front-loading cargo bike. This means generous pedal assist on my end, just looking to reduce my fatigue. Frequent hills in my area so I'm hoping the 20 inch rim will provide more torque for hill climbing and I only need to top out at 20 mph maybe. A 20 mile range with me pedalling pretty much all the time would be ideal.
I was considering using a pair of Bosch or Makita or something 18v 5-6 Ah or so, but thinking a readymade battery may be a better option. Any specific bang-for-my-buck suggestions? It's looking like to start, a 4-drill-battery setup (2 pairs in series, then parallel for additional Ah) would work at around $200.
But my biggest hurdle is a controller. Can someone recommend one that'll work specifically for this motor? Am I looking for a 25A controller to stay under the 30A rating? Some threads said controllers for brushed motors are best for these Heinzmann geared ones, but I'm having trouble figuring out what will work specifically.
