Hi!
I'm having problems with my radwagon 4, and was hoping someone here would recognise the problem.
The motor of my radwagon 4 does not engage any more; not for PAS or throttle.
It started intermittently: when I was cycling, there would suddenly be a strange 'rattling' sound from underneath, and the motor would shut down (while pedaling) while the battery was certainly not empty. The noise would stop at the same time the PAS stopped working, but I could keep pedaling afterwards without any issues or noise (except no PAS or throttle).
I have a video of the noise:

(at around 4 seconds in the video.... I stopped pedalling when I heard the noise)
Maybe important to note: the first few times this happened, if I heard the noise and stopped pedaling, the PAS wouldn't immediately stop working, but a few metres later I would eventually here the noise again and the PAS/throttle would stop working.
The noise first happened occasionally when I was riding the bike for a while, and eventually more and more. Now the motor no longer works at all.
I already disconnected all sensors for brakes, lights etc to exclude problems from that area. If I do a rollback test I can feel the power engaging, but not when I move the bike forward...
Radwagon support have told me they don't know what's causing the noise, but have advised me in separate messages to replace the controller, motor and freewheel. I have the feeling they're just guessing...
So I'm hoping someone here might have experienced the same issue and can tell me what the fix for them was... (I've searched the forum but can't seem to find the same story).
Thanks in advance!
