So the full decision matrix is:
- BBS02 48V 500W (750W) (a minor upgrade); would let me use a better battery and have a better margin when the battery gets low.
- BBSHD 48V or 52V (1000W); can be run with an extra spicy 52V battery for more power
- TSDZ8 48V 750W (1200W peak), the reengineered TSDZ2 with actual thermal capacity
- TSDZ16 48V 1000W (not sure what peak but geez that's a lot of motor)
- DM02 48V 500W (A team that made the TSDZ2 split off and went to make better motors)
- DM01 48V 1000W — I've not read up on it much but it's that same team I'm sure making a solid motor.
Also-rans:
- BBS02 36V 500W (existing motor); A spare would be nice so I can refurb mine without having to be without my bike.
- TSDZ2 48V 500W (I have one); tends to overheat and I ride hard. Not a winner.
- CYC motors: rather spendy. Nice stuff though.
- M625, M615, M225, M255: newer Bafang motors; more expensive, no real benefit, CAN bus is not well supported by third parties yet.
Pros of the Bafang BBS series: lots of parts available on the market. Lots of display options
Pros of the Tongsheng TSDZ series: Torque sensor!
Pros of the ToSeven DM series: Torque sensor, better build quality.
