Bike turns on, but no PAS or throttle

[tptools]

Can you explain what you mean by ?tightened the motor connector?. These look to simply snap or push together, so I am not clear what you are referring to when you say ?tighten?

I'm having the very same issue with my Rad Rover 6 plus currently. Brakes have been ruled put as I've replaced them with different ones that do not connect into the system. Only solution I've had so far is turning on the bike while pedalling or throttle but as soon as I stop it won't output power again.

Let me know if you found a solution! Rads solution is send me all the parts - which are out of stock.

Having the exact same issue with the Radcity Plus Step-thru I purchased in July with 17 miles on it.  It ran perfectly until then and just stopped the next morning.  Displays work and you can up/down the PAS levels.  Zero power to hub motor with PAS or with throttle.  No brake light on and no change if I pump the front/rear brakes with brake light working as normal to see if the motor cut-off is engaged.

Is anyone actually managed to get this problem fixed? I have had a new wiring harness installed and the problem persists. I have disconnected and reconnected the motor connected and the problem persist. My brakes are not stuck and I just don?t know where to go from here.

There is no way to tell if the brake sensor is bad unless you unplug it. Moving your brake levers won?t help much if the sensor is already bad. Unplug the wires coming off each brake lever. They will have red ends when you unplug them. Then test the bike.

If the problem still persists, then you more than likely have a controller issue. It will have to be replaced.

Thanks, this thread helped me out.  I had tightened up the brake adjustment and then there was no power.  Unplugging the brake electrical connectors fixed the problem so I knew it was the sensor.  Loosened up the brake levers and I was good to go.  Maybe design could be a little better but at least I know what's going on.
Thanks,
Frank

I have eliminated the brakes and controller on my Rad Rover 6 Plus.  I have 2 of these and one just stops working and I tested it, not moving it, the day after it stopped and still nothing.  Then the next day I turned it on and leaned it over on kick stand and hit the throttle and it worked. No error codes just no PAS or Throttle.  I had replaced the PAS controller due to dim display and when it died I plugged in the DIM controller and bike still did not work.  Any ideas?  Anyone know how much the 750W motor cost?  Also I have unplugged the brakes, the light and the PAS controller and still does not work.  Everything lights up the way it should when turned on but no PAS or throttle and then after 2 days sitting it works.  We can't trust it so we can't go riding together (wife and I, at 67 years old we really miss riding.

I believe it is your controller.  Have you reached out to RAD for troubleshooting?  Just because you have power from the controller doesn't mean it is working.  I think it may be the brake circuit inside your controller. There are aftermarket controller upgrades you can buy.  Just make sure you haven't upgraded your headlight.  Area13 sometimes has them in stock.  If not try electro world bike.

I had my previous controller with me that had a dim display but always worked.  I unplugged the new replacement controller that was attached when the PAS and throttle stopped working and plugged in the old unit and it still did not work.  Today I rode it a mile or so after sitting for 2 days and decided to work.  The new PAS controller was plugged in.  Problem is the bike can't be trusted.  Don't want to be 25 miles from home and have it decide to not work.  Bike is too heavy for me or my wife to ride that far without assist. From the forum it looks like RAD has a lot of issues.  We love the bikes but now can't trust them.  I have contacted them by phone and email.  It takes weeks for them to respond if you don't happen to get them on the phone.  I have not contacted them about this issue, bikes out of warranty and have 1000+ miles on them. Hoping the general public has the answer.

INOXA  when you say its the controller do you mean the PAS on\off display on the left handle bar or something else.  I have searched for a detailed wiring diagram showing all connections to the harness but only found very vague ones.

[Challenger 528]

I have found that what was called by rad person the PAS controller is actually just a display and switch and does not control the motor.  The motor controller is inside the bike frame behind the battery.  Anyone know what it cost.  INOXA told me about area 13 upgrade for RR6+ $229.  Not sure I am ready to go there yet.

No I do mean the controller.  With an upgraded controller you get one new screen that replaces the 2 you have.  It will be color and is programmable unlike what you have now.  Your model I don't know where it is located but mine is a box attached to the frame.

If a faulty or misadjusted brake handle switch kills the throttle and PAS, wouldn't it also show up as an Error 25 when you power it up?
