750 Watt Fat Bike Hub Motor Core 175mm OEM

Bought this to replace the stock motor on my RadMini. I had previously done the controller upgrade package and wanted a bit more top speed since either the stock Rad motor has a built in limiter or the windings are different. I was able to hit 22-23 on the stock motor. After installing this upgrade motor my top speed is now 27-28. Torque seems to be the same which is expected. Overall very pleased. Make sure you order a new gear cassette because it’s next to impossible to remove the stock one from the rad motor. Also, order one with a smaller 7th gear because you will want that gearing change when your top speed increases. They are cheap, $30 on amazon.

I trust these guys. Just waiting for the gears to get it in the bike and try it out.

At this point I am waiting on a shipment of the upgraded controller and display to install as a kit! The true 750 motor core I purchased is well bult and I'm sure will bring miles of smiles once installed, I've read all the reviews :-) Kyle and crew are the best!

Totally new bike, Thanks guys, Awesome! By the way already have 2, waiting on upgrade kit. This one is bound for a mini4.

I recommend this motor and give it 5 stars. If you are thinking about getting this motor for your Rover then here are a couple of considerations. 1st, if you are still running the stock freewheel on your Rover I recommend not trying to reuse it at this time. However, in order to gain access to the six fasteners being obstructed by the 1st gear (Granny Gear) of the freewheel, you will need to disassemble the freewheel instead of trying to unscrew the entire assembly from the housing. Save that as a separate project and you will save yourself a lot of grief. Once you have the new motor dropped into the old housing with the new flange from the new housing that is threaded to accept a freewheel/ cassette, lubricate/ grease these threads and screw on the new freewheel you have chosen tightening by hand only. I was unable to get the stock freewheel removed and broke 2 of Rad's custom tools trying. I ended up cutting (Dremel) and prying (large flathead screwdriver) until I got past the ball bearings and what remained was able to provide resistance in the CCW direction. Then an 18-inch pipe wrench allowed me to finally unscrew what was left. 2nd, don't try to use the stock controller and this upgraded motor unless you plan on using throttle only. I tried while I was waiting for the taillight controller upgrade to become available. I ended up buying the original version as I was tired of waiting. With this new motor, I had change P2 to 6 to get rid of some speedometer issues.

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
