750 Watt Fat Bike Hub Motor Core 175mm OEM

Finally got around to installing the motor to complete the “big three” (Controller, Display, and Bafang motor. I have the 2019 Rad Rover. WOW this is the bomb. As previously stated not much more top speed, but I’m still using the stock battery, however big difference on torque, going up hills, and acceleration. DO YOURSELF A FAVOR and plan on buying the freewheel cassette sprocket thingy (not included with the motor) If your dead set on repurposing the old one, you’ll need a special removal tool that in itself has to be modified. It’s a huge PIA. I also had to mess with the P settings to get the speedometer correct, I think I settled with #7, but can’t remember the P setting from this writing. The only negative (and it’s very minor) is the throttle transition. When I apply throttle it really bites hard and fast. I’d like to see a smoother transition from a dead start. I use throttle when I’m at a complete stop and crossing busy streets.

Like others, I upgraded the controller first and motor after. I am amazed at the difference. My RadRover now performs better than I could have ever thought. Takes off from a stop quickly and pulls hard all the way to top speed. Even the steepest hills are no challenge for it. I've had my rover for 6 months with over 700 miles, and it feels like a brand new bike. I'm dropping it one star only for the installation experience. For me, this was *not* a simple matter of pulling the new motor out of its case and dropping it into the existing wheel. For one, the freewheel on the existing motor was impossible to remove. They must torque that thing down at the factory. I went through two freewheel removal tools (I also had to grind out the tools to fit over the electrical wire) before giving up and finally just ordering a new 7-speed freewheel (EPOCH 11-34T - you can find them on Amazon for like $30.00) and easily installing it on the new motor. I highly recommend this motor. Giant upgrade and I'm sure it'll handle the increased power from the upgraded controller way better than stock. But order a new freewheel at the same time. Don't bother trying to re-use the stock one.

Initially the motor wasn’t working. I took it apart and re-installed and now it works great! I gave one star before as it wasn’t working but it must have been a “user error”. Thanks. J

I have a RadRover5 2020. I upgraded the contoller/display first then the motor. This motor replaced the stock Bafang that Rad uses. They are not equal. Although both rated at 750w it's argued that Rad uses a customized version that's cheaper in design and cost. I live in a hilly area so power and torque is important. This motor has more torque than the stock Rad motor. It's a little tricky to install. You need a T20 Torx bit that's the security version. It's easiest to purchase both the motor and freewheel cog. The freewheel is shipped installed on the motor.

I just received the true 750w motor, and I'm sure it will meet or exceed my expectations. Any problem with it will be on me or Bafang, as Bolton is not installing it and did not make the motor. My total of 4 order history has been flawless. The plethora of information on all things ebikes Kyle gives us all is awesome. So this is more of a Bolton Ebikes review and a thank you!

Hi , Bolton team this is a great upgrade have not been disappointed, 1800 kms and 4 months of riding going great .Thanks Kyle and the team excellent job !!!

This site was great, I ordered and got it quickly. Just be warned that this part DOES NOT fit the new Rad Expand 5. They swapped the cord for the rad expand 5 and it now comes out of the same side as the freewheel and the motor now spins the opposite direction.

I have a 2020 Rad Rover ST-1. As a stock bike, my battery life wasn’t that great and my bike topped out at 24mph after changing the programming per the YouTube videos. It would hit 24mph on a good day. First, I changed the controller/display. I then upgraded to the 52v battery from Area 13. Holy moly! Bike gained the torque. Much faster from a stop and top speed now 27.2 when the battery was its freshest. The range was now unbelievable. I could ride 2-3 times further than with the stock battery I upgraded the motor yesterday. It makes less noise and my top speed jumped up by 6.5mph. I now top out at 34.0mph on a fresh charge. It will then drop down to 31-32.5mph for the rest of the ride. Didn’t notice an increase in torque. That came with the battery. Torque and Range - comes from the 52v battery Top MPH of 34 - comes from the motor. All i can say is upgrade in this order. 1. Controller 2. 52v battery 3. Motor

I did controller and motor swap Plug and Play awesome upgrade I love it
