By far the most popular upgrade available, The Upgrade kit includes a new motor controller and new color display.  The combination allows you to finally unleash the full potential of the stock motor and battery.  This is THE upgrade kit your friends have been talking about.

35a controller and New Color LCD8H.

Plug and play for 2016-2018 Rover bikes. Please note that the controller has a tail light plug that will not be used. We do not recommend upgraded lights as it can burn up the headlight circuit.

Plug and play for 2019-2021 Rover models. (Up to Rover 5) (Not compatible with Rover 6)  Will only work with stock 200 lumen headlight, will not work with the 500 Lumen headlights. THE 500 will burn up your controller.

Mini - Although also typically plug and play for 2018 and prior, this controller is substantially larger than stock and will not fit inside the frame or stock mounting locations.  May have a different battery plug.  Please check your bike and photos before ordering.

City or Wagon - Untested, but customers have reported it works well. Setting adjustments may be required. Controller may not fit correctly. Additional mounting hardware may be required.

Rover 6 + STEPOVER & STEP THROUGH- Does not work

Runner - Tested and working!

Rad 5Expand - works

Mission- Works, we recomend turning max power down.

    Controller and display were simple to install (plug and play.) Power increase was great! Mounting hardware did not line up, completely with my (step-through) frame, however some heavy duty zip-ties (from Walmart) did the trick.

    Upgrade kit...

    Posted by Evan Loeffler on Sep 2nd 2023

    The kit is a lot faster than stock even with my shinco 241 tires, I’ve been riding my radrunner to school everyday for the last 2 weeks and its had no problems yet. My one complaint is when doing wheelies at more than around 5 mph if I let off the throttle it takes a second to come back on making it really hard to keep it up. Stock controller had some delay but it was manageable whereas this is not. Bad for wheelies great for normal riding or cruising. If there’s a way to fix the delay please let me know.

    The Upgrade Kit 1st gen...

    Posted by Judd Baumann on Aug 30th 2023

    The kit is fairly straightforward. Not sure if I can use the taillight cable if my bike didn’t originally come with one but, I don’t see why not. The kit comes with the display shown in the description but, that is not the display that is covered in the online video. The display also comes with another menu option not discussed. Still tweaking the parameters after two weeks since there is no concise info about what changing certain parameters will actually accomplish or what they pertain to. I have noticed the torque boost. As for top speed, I haven’t been able to get any gps to respond fast enough so I can verify (this is not area13’s problem). Overall I am pleased and look forward to seeing if I can fit the 19ah rad battery upgrade into my 1st gen frame; I just don’t want to pay return shipping if it doesn’t.

    Posted by Gavin Christie on Aug 30th 2023

    My upgrade kit arrived quickly and all the plugs fit, had it installed in less than an hour. Hardest part was mounting the controller. Performance is great, lots more hill climbing power! Although I guess I'm going to break something in the motor sooner than later with all the additional stress/wattage. I would like to know what all the settings are for so I could tune it in. Great kit, highly recommend....when is the Rad6 kit coming out?

    Thumbs up for hill...

    Posted by Phipps, Margaret on Aug 29th 2023

    I am not an experienced bicycle rider, never rode as a kid. We purchased 2 Rad Rover 5 ebikes 2 years ago and now have about 4,000 miles on them. Needless to say, we absolutely love them. I still had to really work hard on some of the big hills we have encountered (hubby able to power up with strong legs) so the upgrade sounded like a good choice for me. Success! I am now able to climb those hills alongside my hubby and my knees don't have to strain. I use PAS 1 most of the time so as to have throttle available at all times. I can't take off without the throttle due to knee problems and the fact that I wobble at slow speed ... lol. The extra power at low speed was a little intimidating at first and I still don't know if I love the faster pace with each pedal rotation when I want to go slowly but feel that it's something I'll get used to hopefully. I also am encountering some surging when trying to apply just a little throttle even though I'm keeping the throttle steady. Don't know if that's me or something to do with gearing, PAS or ?. Overall, I'm very happy with this product and glad I purchased it. Install was fairly simple, just followed youtube video instructions and programming was also pretty straightforward. Thanks for all you do for the ebiking community Area 13. Keep up the good work
