  2. can this 12 in hub motor go slow enough to be able to walk behind or to the side? Approximately 4 miles per hour and having about 50 lbs it is carrying. That is what I’m looking for. Also have an on/off switch and the ability to dial in the speed.

  3. Good morning, I have a few questions:
    We are looking for the Rear Drive version of HUB12SR
    which is 48V 350W ,
    Do you have the sine wave controller matching this?
    Can the cover be chromed too?
    Is the diameter of the wheel plus the tire 12 inch?
    we want the front wheel without motor,so do you supply the 12 inch front wheel without motor?
    Can this motor have a drum break?
    Is there any other tire options?
    :Do you have a technical diagram.

  4. Any chance to make it maximum efficient on 82V?
    What about use it as a front wheel?
    Any chance to get disk and support with this wheel?

    • Sorry, the max voltage is 48v. It is ok to use as a front wheel drive. We can add a disc braking base to the motor so that it can support disc braking.

  5. Hello,

    i have some questions: Does the motor have a disc brake mount support (6 hole type)? Is it possible to use a 12″ x 1,75 tyre? Thanks

    • Hello Christian,

      We an use a extra flange to make the motor using 6 hole disc braking. Currently, the tire is only one type. You could use the 1.75 tire at your side.

  6. Hi,
    I’m looking into building a 2 wheel scooter for adults running on lifepo4 36v 10Ah battery. I need 12″ power wheel able to achieve 20kph with 100kg adult (120kg in total). What power should I look for? Do you have such hub size and power?

    • Hello Konrad,

      For the motor power is ok, We have two kinds of 12 inch motors, what is your scooter fork size for motor?

  7. I am looking at this motor for a mountainboard project (Outback Mountainboard), what is the max speed at 48v 350w front 100mm dropout type motor?

    • For dropout size 100mm,we need to customize it for you, and the lead time is a little long. The max speed can reach 35km/h

  8. good Morning,

    disc brake

    tanks Paolo

    • Hi Paolo,

      could you let me know what size of the motor do you need? this 12inch motor? We have 100mm fork size front wheel motor 36v 250w version.

    • Hello John, what is your application? why so lower power and what is the dropout size of the motor you reqestion?

      • My application is driving a robot, I don’t need any more power since my payload is 40 to 80 lbs across 2 wheels. I need about 13 Nm of torque.

        Is it possible for a 12v Brushless version.

        How about having the axil only on one side like some of the smaller scooter wheels.


        • Hello John,

          It is ok to make single shaft motor, but for the voltage, we only have 24v version.
