Rad Rover 6+ Upgrade Kit V2.1

The stock controller is junk. This is a great one to replace it with when it breaks. And gives you a lot more speed and power

The upgrade kit is great. But there is one small glitch. The system allows me to set the assist rations for PAS 1-3 and 5, but not 4. It doesn't matter which value I enter for 4, I get 100% assist. I prefer 50% or 60%. Having only 100% is a problem for me.

The new upgrade was easy to install and works flawlessly. I was left with very few options to be my bike back on the road!

This controller turned my RR6+ into a BEAST ! Also the ability to adjust and tweak the setting to gain the most out of the RR6+ is awesome!! I would highly recommend this controller to anyone who purchases a RR6+???? !

More power adjustable speeds the bike I was looking for.

Did not realize how rubbish was the Radrover 6 torque until i installed the area 13 kit; What a huge difference it made. My riding experience has been so much better . Thank you guys!

Big boost in torque and power! A real game changer!

I was very hesitant to install the the 35amp controller due to the restriction of full throttle based on what PAS number was selected but once that issue was fixed allowing you to have full throttle at any PAS number I pulled the trigger and purchased one. At this point I have zero regrets. It's a well made product that comes ready to plug n play directly to the factory cables. It makes a huge difference in acceleration and torque, especially when going up hills. I almost never strictly use the throttle. I almost always pedal and use PAS at some level and I can still tell a big difference. My biggest complaint is the installation/programming instructions. They need to be better and more clear with more detailed information on programming. I basically had to go to Youtube to watch an installation video of the product on another bike to get the basic idea. If you have basic DIY/mechanical skills it's pretty simple to install. The biggest issue is the programming directions. They really don't exist on the paper they send you. I had to go online to find the pass code to enter the programming mode of the display. Only then can you make necessary adjustments. I had to revert back to Youtube to watch videos on what some of the settings meant as well. All of that info should be included with the package in a detailed instruction manual, not a photo copy if very basic installation instructions with small pictures. All of that said, I've very happy with the purchase and would definitely do it again.

Installed the upgrade kit last week and went riding for a bit. Immediate power upgrade noticed along with increased information available on the DS103 display. If you want more power out of your RR6plus, this will do the trick. I have a rear rack and installed the controller there next to the downtube. Just be aware that with all that new power comes a significant drain on the battery. Range will drop significantly if you are using 4 or 5 or heavy throttle. It will pull down voltage for a moment and then will slowly rise back up again. I did a steep climb up 4 miles ( 1500ft rise), and then a total of 12 miles on 1/2 battery. I weigh 175 lbs. Hope that helps. I would buy this again in a minute.
