How much power will this add?

We have dyno tested the stock RadRover 6+ before and after installing this kit.  Peak performance at the rear wheel was 716 watts and 27.3nm of torque on the stock bike.  With the upgrade kit installed we doubled power to 1,503 watts, and increased torque over 50nm!


THIS IS NOT COMPATIBLE WITH OTHER RADPOWER MODELS!  Please see our other upgrade kit for other bikes.

Has not yet been tested with the "premium" headlight from Radpower and is not recommended at this time.

Compatible with both 48v and 52 batteries.  (NOT recommended for 60v)

*The Upgrade Kit is created for specific models of Rad bikes, and that name is used for part compatibility or identification only. We are not affiliated with that company and this item is an aftermarket part.

    Faulty Product/ Poor...

    Posted by Kenneth Hoffman on Nov 17th 2023

    I installed the controller upgrade kit on my RR6+. There were not installation instructions provided with the shipment and after installation it did not perform as advertised. Specifically, the throttle not only didn't work but throttle use caused the entire electrical system to shut down. I contacted Area 13. They sent me set- up instructions electronically and I changed the default settings as directed. The throttle still does not work and throttle use shuts the system down, The only way to get the system back up is to remove the battery, discharge the system, and reinstall the battery. I have been trying to get Area 13 to authorize a return for 2 weeks. I have gotten nothing but the runaround. I would like to exchange the product and try again, but what a hassle to get through this. If you want something better than 1 star replace my defective unit with one that works like it's supposed to.

    I live in an area with many hills. Upgrade allows you pedal normally and the motor gets enough power to handle any grade of hill. Torque and power are amazing.

    Power and...

    Before the upgrade, my RR-6+ was a real slug and after the upgrade wow, now we’re talking power and torque. Area 13 was very quick to walk me through the settings to turn this bike into the way it was meant to be. Also, this bike now blows the doors off my Himiway cruiser. I did notice only about a 2 mph gain to high end speed but the increased torque makes up for it. I would definitely recommend this to anyone who wants to improve their RR 6+.

    I have a RadRover 6+ ST and it was very easy to install the Area 13 controller. There were only 3 wires to unplug from my old controller and plug in to the new one. The bike’s performance is outstanding with the Area 13 controller and I like the new display. I give Area 13 high marks for their support while installing it and for designing a great product.

    Upgrade can not be simpler. I had a few questions about settings and Area 13 was prompt in answering. I made a few settings changes to suit my riding. i had to change wheel size to 28" with stock tires. I also changed the Turn Gear setting to 1 so i can set throttle max depending on PAS setting. (helps me just cruise the beach). Not as many settings as KT system but is much quieter. Top speed is the same as stock but getting there is waaay better. i use PAS 4 and bump up to 5 only when passing. No brainer upgrade. Motor does get warm on long throttle cruises but nothing to be worried about.

    Plug and play. I ordered without noticing the note indicating not compatible with the RR6+ step thru, but if you install the battery cable first since it's a little short, it works fine. Jenny from Area 13 responded to my questions promptly about some of the custom settings. Lots of power now, can't wait to try it at the hunt camp steep hills...
