Hey all. Anyone happen to know an EU source for the wiring harness? [As it happened, after seven weeks they were able to send me one!] We hoped it was the solution to the Error 30 messages that pop up soon after powering on the bike. It wasn't.
Apart from removing the battery and checking ALL the connectors very carefully and reconnecting them, is there anything else to check? The bike's been out of commission for two months. It was great for the one month it worked!
Which model are you running?
Error 30 represents either the controller and/or display are having trouble communicating with each other. You can try replacing one, the other, or both.
Tell us more about error 30. Are you able to run the bike at all? Does it pop up randomly?
Try unplugging everything from your bike apart from the display, controller, motor, and throttle. Does it still kick up the error?
Hey thanks for your message. The RW4 is the bike. After unplugging everything except the controller, am still getting the Error 30 message; does that mean the controller is the problem? Or the display or check both? The error message pops up about 20 seconds after powering on.
Did you also unplug the pedal assist sensor? It's the short one that leads to the small black box at the crank.

The display and controller work together in tandem, with the display doing the brains of the operation and the controller supplying electronics and driving the wheel. They need to be in constant communication. If there's a problem there it really could be one of the two or both. I just want to rule out other potential variables.
Really grateful for you following up!
I hadn't unplugged the PAS cable (the orange Julet cable that connects to the controller, correct?) and just tested...
Still the Error 30, but another variable eliminated –does that mean it's down to the display or controller?
I guess one more quick test would be to test power with just the screen and controller, unplugged throttle, unplugged PAS, no motor, etc. See if that changes.
Beyond that yeah, that's all I've got.
Thought I'd unplugged everything, but the motor and throttle were still connected. And....Error 30!
At least now we can confirm it's down to the display & the connector.
Onward!
Update: as of December 14th, I'm still awaiting a solution (i.e. parts) from Rad.
