rear bafang hub motor

[ePorsche911]

what kind of ontroller for this motor (sensorless I think)? is a pas necessary ? a ls675 ,a sinewave controller ? a torque imitation controler ? (from pwpower,bmsbattery ?) what are the differences between these controllers ? Whre can I buy thr cobbetors for the motor ? It s a hollowteh shimano bottom bracket.

Your hub is sensor less only three pins.
You need a square wave/unsensored controller, Torque simulation means it is a current control controller and uses a different current load for each of the five power levels.
Sinewave controller is of no use to you with your hub.
Yes you need PAS to be legal, it is a requirement to pedal for power.
For hollow tech you need a BZ10C Pas sensor.
If you want a throttle you can add one if you wish.

But lsw675 sensorless seems to be a sinewave at bmsbattery. Which can of controller ? I Think that the amperes are something important and the watt too. (250watts) But there are a lot of sensorless controller and I don't know how to choose . The cheapest ? A torque simulation or not ? I want to ride bicycle and I just want help when it is climbing too much or when the wind is strong and me not strong enough.
