The motor is very good for  updating the Razor MX650, we have a customer wrote a post here:

The sprocket on the original motor swapped directly on the the brushless motor with no modifications and was a perfect fit so I ran with it.  One point to notice is that from the face of the stock motor to the middle of the sprocket was 14mm.  From the face of the brushless motor to the middle of the sprocket was 16mm.  This was resolved by putting a 2mm washer in between the face of the motor and the motor mount thereby holding the motor back such that the sprocket was in the original position.  You’ll notice there was a 10mm difference in length so on the backside I needed 8mm spacers to make up the difference.  A combination of a spacer and a washer was perfect.  Ace Hardware had them.  The mounting holes were identical to that of the original motor and the original bolts were long enough that they could be used so the swap was easy.  The new ESC is a bit larger but will still fit in the existing location.  I placed it up where the 3rd lead battery went as I’m not using that area.

  2. Hi Tony,

    I want to upgrade my son’s razor to the 2000 watt motor. Do you have any designs for battery configurations that meet either the 60 or 72 volt ratings and fit the frame?

    Anyone?

    Thanks.

  3. I have the Razor MX 650 and I want to upgrade it with the 48v 1600w motor and controller. Is this literally all I need to make this work properly?? I don’t need to get a new throttle or sprocket??

  4. Hi Tony,
    I need the price of a 1600w or a 2000w motor. I will be operating at 48 volts.
    I understand the 2000 watt motor has a heat issue or maybe they have that taken care of now. so if you could give me a price on a 1600 w Motor and a controller and a throttle with the voltage meter build in, I believe that’s all I need for my mx650. Thanks Fred

    1. Hi Tony,
      Maybe I should ask you your opinion first if you had an MX650 what motor and controller would you put in it if it was your own, also I’m going to run 48 volts will I need a 48 volt charger or will it 36 volt I have work and I would like one of those throttles with the voltmeter built into it. If I’m forgetting anything be sure to mention it and give me a price on the whole thing.
      Thanks Fred

      1. Hello Fred,

        1. For the motor, we have two common version, 48v 1600w, and 60v 2000w, both have no heating problem.
        motor link is here https://www.uumotor.com/webstore/bldc-motor/2kw-electric-small-motor-bike-brushless-motor

        2. For the controller, we have it a multi-voltages working, that is from 24v to 60v battery, all is ok to direct to connect to controller to let it work.
        controller link is here https://www.uumotor.com/webstore/24v-60v-2kw-brushless-motor-controller

        3. For the throttle, we have voltage-meter throttle.

  5. First, confirm your motor frame is 135mm end to to end. I purchased a 135mm and received a 145mm – won’t fit on the Razor MX650!

    For this motor to work on a Razor MX650, the motor shaft will have to rotate CW when looking at the end of the shaft. I am running 72-V, so I have a 48-V 1800W BLDC motor connected to a 72-V 60-A sine wave controller, and the motor rotates “CCW” when looking a the shaft end. I need “CW” rotation.

    Does your stock motor rotate CW with a standard BLDC motor controller? Or does “your” controller have a “reverse” connector to jumper for reverse rotation? Is it possible to wire the phase and hall wires differently to rotate in opposite direction – “CW”.

    I want to run a 72-V battery pack & controller. I assume your controller will not run at 72V – please confirm.
    So what is the difference in the 48-V version vs. the 60-V version motor? Is the motor physically different?

    Please advise. I need to know before I order.

  9. Do you have a 36V version of this? Slightly lower power is ok, but was try to not have to add a fourth battery.

  14. Good day,
    We are looking at doing the Sasol Solar Challenge next year September 2016 here in South Africa. We would like to have the Power, Torque, Voltage, RPM and Efficiency curves of the 1500W, 48V high 5600 RPM motor to see if it will fit our application. Further what is the cost and quantities of these units and what controllers are available for these units, and do they have a re-generation option available.
    Don
