Also interested if it doesn't work with Late

Thanks

Thanks.

When you said it pushes the chain. I mean the motor on the rear pushes the chain towards the main chain ring.

Like if the engine was trying to help me because I was pushing the chain but I am not pedaling.

It also happens with help deactivated and maybe with engine off, so maybe you are right it is related to the derailing system that is not well configured anymore. No clue with that would have changed suddenly.

I got the same issue 2 years after start using it on a radw4.

I baught boat springs form Amazon and it works like a charm. 10$

Hello,

I am the desperate owner of a radwagon4. It has been a very stressful and long journey et that seems to never end.

I almost killed my kids twice with the exploding tire issue and globally radpower support team is very nice but never solved anything. From dead controller, dead battery pack to defective wires etc.

The recent problem I have is that now when I stop pedaling the assistance goes full throttle and pushes the chain so hard it derails. I cannot drive more than 5 minutes before it happens and I don't know what to fix here.

Any help on what / how to diagnose then fix would be appreciated.
