Hello again,
I have a few more questions:
1. How many watts does it draw on 72v witj no load?
2. What is the maximum and minimum and minimum watt draw?
3. Does the controller have regerative braking?

Hello,
I am interested in this product. Is it possible to get this engine with 4 kW? If not I think the 3 kw is enough to accelerate 200kg to 60km / h. How big is the control box for the engine and is it waterproof? Does the engine support recuperation? Is it possible to install a disc brake instead of the sprocket?
Thanks for your help
Stefan from Germany
I would like to know this too. Does it have regenerating brakes? If not do you have a different controller option with regenerative braking? Would also like to know if the controller and hub are waterproof and down how many meters.
Thanks

2. Wheel rotation sensor output
Best regards

Good morning, my name is Enrico Carmellini, usually do e-bikes very powerful and beautiful. However, for an experimental vehicle, they need from you, or from a competitors, 2 motors inside a wheel.
Each wheel must mount a tire from 110/80 R19.
From this it follows that each motor must be within a wheel rim for motorcycle 19 “.
The power must be from 5000 Watts, to have a lot of shooting and the minimum torque shall be 120 Nm for each motor.
I need the kit complete with control unit and connecting cables and programming (number two complete kits).
Can you help me, please ???

For gearing.

im interested in 5 kw hub motor with rim. hill climbing and speed is important so what batteries do you recommend?
looking at good range.
luke, sydney australia
what wheel size do you like?
I’m interested in the 5kW version motor.

2. Can this be mounted to the front wheel?
3. Do you have a picture for the throttle control and other accessories?
4. How stable can you hold a certain speed?
5. What type to battery do you recommend?

If so will both the hub will move with one throttle ? And kindly update if shipping can be in India also. regards
It is battery to use a 40ah or higher capacity battery. To control by only one throttle is ok.
