BUMP
Anyone?
 
looks like an OEM manufacturer only system to be built into the frame. still no decent off the shelf retrofit torque sense system out there
 
I asked my supplier of Bbs02 750w if I could get one and he said they don't manufacture yet. Or maybe he just doesn't have any... I also sent an email to bafang. Using their online contact form.. No reply
 
I understand that Lunaycles has one on test at the moment it's all pretty hush hush ,I have the Max Drive system ,uk compliant to 250w 14a ,keep current was set at a really low 30% , but underneath its a 25a controller and the g33-350w unit , been in with my cable and tweaked it a little , it's mighty good, super silent , I have to fit better battery as I get huge sag with a 10ah , speed changed by way of the sub menu on the display.
 
This >1000W Ultra fast TRUCK from copenhagencargo.bike is in the making. Will also come without motor and 250W Bafang MAX or Ultra 500W, 750W or 1000W

Biktrix.com/Biktrix.ca is now selling the popular Juggernaut with the Bafang Ultra drive, it's beautifully integrated and also available with several frame-integrated battery sizes (including the new 20Ah, 1,100 Watt-hour pack). Test drove one yesterday and was very impressed, weight distribution and overall construction was top notch!

Large diameter X small width = small diameter X large width = same torque = 160Nm

With a small width, you have more place behind for pinion.

Large Width X large diameter = too much power for 1000w motor .
