I question your 1642W figure. The controller does limit power to the motor to 750W.

Dick, I believe Altema has upgraded his controller to 35A and was using that to drive the stock motor.  In his other thread comments, he said he was actually testing to see if he could fail the stock motor with 1,600w input and could not - the motor is fine.

Yes, Jim is absolutely correct. I was using an aftermarket controller, and the Rad motor handled all that power fine. The nominal rating of a motor is the amount of power it will handle at 100% duty cycle without exceeding thermal gain parameters. It's science, and going on "looks" is not.
By the way, attached is a screen capture from the video of one of my acceleration test runs, with the Rad motor peaking at 1746 watts.

Question for you Altema. My Rover 5 has the stock motor but I upgraded to the Bolton controller which really increases output. Do I need to be careful not to burn out this 500 watt motor?

Never used. Put my Cloud9 on for my skinny ass!

the 35a bolton radpower upgrade is the best mod i've done to my radrunner 1...so far!

i've been using the 35a bolton upgrade since last july with zero issues.

definitely increases the bottom-end performance - would recommend!

Bolton states the stock 750 watt motor doesn't like going much over 800 watts. Are you going much over that?

Just got my RR5 and thinking of changing out the controller. All I read about the Bolton is positive. Has anyone had any issues? Hate to void the warranty this early in the game

Anyone put their 35amp controller own their rad city (2020)?

Bolton's website states they've not tested their 35amp controller on the Rad City. They do state some customers have said it works, but some adjustments in the settings may be needed.
Anyone out there put it on the new Rad City version (2020)?
Thanks

Which bike did you install the Bolton 35 amp controller? Their website sounds kinda iffy with the Rad City
