Relating to the original question of this thread, I'm after an electric drive for a Surly Big Dummy, for hauling cargo, mostly flat riding but an occasional short 8-10% grade.
The Mac seems a good choice, and I'm considering running either a 10t on 36V or a 12t at 48v, on the front wheel so that it's independent from the drivetrain. Using the simulator, they seem to end up practically the same efficiency, if the throttle is adjusted so that both motors are running the same speed for each grade. Any practical considerations between the two options, will the 48v need more active PAS level adjustment to maximize range? I'm after good battery economy rather than raw speed, and 30-35km/hr with good run time is preferable over higher speeds.
The biggest shark pack from EM3EV is a 48v 13s5p jumbo shark pack. I was thinking a 36v 10s7p in the same case would be a good size, but they don't have one listed. Their biggest 36v is a 10s5p shark pack. Would a 48v 13s5p with Mac 12t give a similar run time with lower throttle, compared to a 36v 10s7p Mac 10t?
