Some info

I plan to get a Bafang Middrive conversion kit. Then I am getting one of the smallest gear wheels for the motor to max out the torque. I plan to be towing some weight behind the bike, around 400-600 lbs. This would be on all sorts of terrain, with a single narrow wheel. What kinda of situation would I be looking at in this situation for startign, climbing, downhill, and stopping?

Procure a BBSHD which has a 30 amp controller and can support 52V, so about two HP (lots of argument about efficiency etc, blah, blah). There is a 30 tooth chainring available. Should be able to climb a tree with that combo.

BBSHD, I have heard that in conjunction with BeFang but I focused on the fang because my memory would hold it easier. What is the difference between the two?

Bafang BBS02 is "rated" @ 750w, and BBSHD 1000w. The BBSHD is supposedly about two pounds heavier (I only have BBS02's) and has more copper to provide more power and dissipate heat more effectively.

You want the big one (BBSHD). That one will take the heat and power you'll need with that load.
