    BBS01 vs BBS02

    I went with the bbs02 48v because the motor is slightly bigger so sheeds heat better and you have more power. The efficiency at low levels are the same between the bbso1 and bbs02 if used at same power. If you take a 48volt 15ah battery you have the same amount of energy as a 36v 20ah battery...

    need a faster commuter

    When you play with ebike.ca simulator with the 40amps on the bmc torque (10t) vs bmc speed (8t)you do see that there is a difference of 30newton meter at 0mph for the 10t and at 25mph 8t has 15newton meter more. You can see that the 10t is more torque at start but at speed 8t has more torque

    New Bafang Crank-Drives

    You can ask for another battery he will just limit the amps to 20 because of the battery. I seems that also would be good since the 750w does have some problems over 20amps plus the controller a 9fet with 750w. Thats what i did with the 29e rectangle 14ah battery that wasn't offerd at the start...
