Do you sell the battery as well as the hub motor? Also, Do you have a trigger type control instead of the twist?
I have a kick board similar to the one in your pics but is does not have the cross/Tbar. It has a knob. It is a K2 Kickboard style. Please let me know and also if you have a 3″ hub motor as well. Mine would be best suited for the smaller size wheel.
Thank you

Hi. I would like to discuss the purchasing details of the 4 inch hub motor scooter kit
please email at sales@uumotor.com for the details.
I want to use the HB4 kit 150 W on my manual wheelchair.
Will I be able to start from zero speed using the twist controller?
Yes it is ok.
Hi I can’t find the 4 inch kit in the online shop ?? I want it in the UK ..?? HB4KIT
it is not listed in the online shop yet. We can discuss the buying via email. I have sent you an email about purchasing details.
Can you post this item to indonesia??
Yes, we can.
I’m looking for a motorcontroller for the 10 inch hubmotor to be used in a rc car.
The problem is that most controllers don’t have reverse function.
I want the motors to be controlled by arduino/raspberry pi and also rc joysticks.
Do you sell motorcontrollers for that?
Also i want to build a 4wd wheelchair using 4 of these hubmotors, do you have a controller who can steer that?
Sorry that we also do not have the controller you are looking for.
