Q: I would like to purchase a 27.5″ electric hub motor kit that fits in 135mm dropouts and I have a 72v (20s) battery capable of 80A continuous that I would like to use. Several questions please:
A. Can I buy a 27.5″, Freewheel, Rear, Wide Rim, kit that fits in 135mm dropouts with the “2000W ~ 5000W programmable controller” instead of the controller that normally comes with the hub motor kit and if yes, what would the total price of the hub motor kit be before shipping cost are added?
B. What is the internal width of the widest 27.5″ rim you have available?
C. Can I get the 5mm phase wires with the motor configuration I specified in “A.” above? If yes, how much would it change the price? If no, what are the largest diameter phase wires I could get?
D. Do all Direct Drive Leaf motors now use the .035″ thick laminations? I would definitely want them.
A: A. 135mm dropout – max make 48v 1500w rear bike motor,see below drawing. no room to make 2000w motor. (This 48v 1500w motor with 3mm phase wire can work with 48v or 52v or max 60v)

But, if no freewheel, not pedal, can make it to be 48v 2000w front bike motor(see below drawing) that fit for 135mm dropout and can use “2000w~5000w programmable controller”
This 48v 2000w motor with 6mm phase wire can work with 48v or 52v or 60 or 72v batteries.

We have three kinds of 27.5 inch rim, one is 23mm width, the other two is 25mm and 32mm width. (Max 32mm width)
If 26 inch, we have 25mm, 32mm, 80mm width rims.
B. Our 27.5 inch 32mm width rim, internal width is 25mm
C. 48v 2000w can use 5mm or 6mm phase wires. (But 48v 1500w max use 3mm phase wires.
D. All of our motors use .035″ thick laminations
Q:
Two more question regarding the “48v 1500w rear bike motor” phase wires:
A. Are the phase wires 3mm in diameter or 3mm in cross sectional area?
B. Is the 3mm dimension for the actual copper wire or the overall including the insulation?
