Has anyone upgraded their Radrunner Plus motor?
« on: March 09, 2021, 08:27:59 AM »
I ask because I tried to this weekend and it seems the motor on the RR Plus is a different motor than the other models in that the cable exits the motor on the brake side and not the gear side.

This makes the replacement 750 watt Bafang motor I bought incompatible with the stock setup.

Can't wait to hear from you Rad dudes!

Yes, it looks that way.  Just got my RR+ a few weeks ago and the motor I ordered won't work.  But just the controller upgrade made a huge difference already.

This controller upgrade you speak of, what does it improve? and what company did you buy from?

The Bolton 35A controller.  It delivers about 2.5x the power to the motor.

Ohhh 2.5x, nice. Looks like I will be making a future purchase from Bolton.

We went out on a couple of rides this past weekend and for some reason the Rover 5's seem to be faster. My son and his friend where on the Rover 5's and I was on the Runner Plus and they would just fly by me..I went into the settings and the wheel diameter that was selected was at 22 and not 20. I wonder how this selection affects the speed of this bike.  Gonna call Rad Power later today and see what they say.

Thanks for the info on the controller!

Just checked with Bolton and the upgrade kit is out of stock. Hope they stock 'em up soon.

Wheel size measured the diameter of the tyre and the wheel, so even if the RR has a 20" wheel, it's closer to a 24" total outside diameter. A different setting will cause the speedometer an odometer to under/over read.

The stock RR controller is good for about 19A continuous output, or about 350W, the Rover outputs closer to 750W.

That makes sense. If I remember correctly I believe the settings on our Rover 5 one was set at 26 and the other at 28. This weekend I'll compare speed with GPS and see what setting is best. 

On another note, I just ordered the 35A controller for the Runner Plus, I hope there is a noticeable difference, if there is then I'll go ahead and replace the controllers on all our bikes.

Will this motor found in Ali express be compatible with the radrunner  plus? Looks like the wire exits in the brake side.

That is a 1000w motor and I'm pretty sure it won't fit in the 500w/750w casing.

It will greatly improve the torque of the RR+. You will get across the intersection quicker on full throttle and it's hill climbing abilities will be effortless.
