I am looking to build an e-bike, starting with the Mongoose Dolomite. 5000W is probably too much, I see you offer 1500W hub motor kits, but I did not see any information about 4inch wheels for the fat tire bikes.
Do you have a 26 inch bike motor kit for the 26 inch fat tire bikes, rear drive, 1500W or more?
With a 9 speed cassette is there enough room for the hub motor in a 135mm drop out ?
I see now that my Shimano 9 speed rear cassette should be the same width as a Shimano 7 speed. It is the spacing of each gear that is different. However, if I am to purchase your kit, I would need you to supply the 9 speed freewheel because I assume your hub motors use freewheels and not cassettes. Right now my bike is a cassette.

Unless it is possible to supply this bike motor in the kit instead:

I should be able to mount my cassette to this motor. Can we do that instead?

This is no longer for fat tire bike so please ignore the first email about the fat tire kit.

It is for a regular mountain bike so no need to worry about 3 or 4″ tires. I have regular mountain bike tires, 26 x 2″ right now. Once I do the electric bike conversion kit, I may switch to more narrow road tires like 1.5″ or 1.75″ so the regular double wall mountain bike rim is fine.

So I made a new order with the individual parts and I excluded the brakes because I do not need them. However, it came out to be a little more expensive than selecting the kit but, I would like a double walled 26″ rim added to the hub motor please.

Just wondering what type of connectors come on the motor controller? I am ordering my battery and need to know what kind of connectors it has. Do you have any pictures or description?
