Sorry, I hadn't received an alert to your response so apologies for the lag. To my mind the problem is related to the battery seating. Though I don't get why the light being on is such an issue. The other day I lost power cycling along and the control panel flashed an error 30. Removing and slotting the battery back down hard remedied the problem.

The hand throttle barely ever seems to have any impact, as I understand it's only an assist in the EU?

I will have a play with the throttle and see if I can diagnose any further cause and effect.

Hi,

I'm new here and am seeking some advice regarding our Radwagon 4. Recently it has been unreliable, which we initially suspected was due to the battery seating in the connector. Now with the battery firmly seated we only get drive from the controller with the lights on. If you turn the lights off, the motor ceases to respond to any PAS input. This thing isn't that complicated, so I'm at a loss as to why the light function is impacting the drivetrain operation.

So as I said, any help with the above or similar experience would be gratefully received. I don't want to have to send this behemoth of anywhere for investigation.

In case it matters, we have a European specification bike in London.

Thanks in advance, Chris
