    I've returned the motor as I found that the problem was my planetary gears were worn out. I bought new gears from you and am waiting for my refund for the motor.

    I have a RR5 since 2019. In early 2020 I installed the 35amp controller and display upgrade. It made a big difference. Last week I finally installed the 750 watt motor to complete the transition. I now have about 100 miles on it and it is a yet again a significant power and torque increase. I have to fiddle withe the display settings a bit still to get them dialed in. I'm loving the new life it is providing my ride! Install was simple and took about 20 min. Should have done this years ago.

    Great power increase, and torque. Went from 25 MPH with a Rad Rover 5 to 30 MPH. Just need 52 Volt battery now to extend range. It does reduce your range. Great upgrade. Not a problem with a lil ability to do yourself Definitely recommend

    I am still experimenting with the settings but this motor makes a big difference on my Radwagon 4. Definitely a must have upgrade.

    Shipped quick from seller and packaged well. The motor itself typical china made. Motor windings are better than bfang but still not that great. No fault of the seller.

    Added motor to a rad rover 5. Had already installed the bolton upgrade which gave me 25mph and tons of torque. The new motor added some more torque and put me up to 31mph.
