I would check the PAS disc.

Is it throwing any warning lights?

I've a spare stock controller here in Claregalway if you want to test with it?

But it's also possibly the pas ring as mentioned above.

My RadRunner just had PAS problems at 2000 miles. I probably caused them by taking off the crank and over-torquing.

My symptoms were that the pedal assist would cut out and I would get 000 watts displayed quite frequently. I could change the PAS level and get some response, or gear down and get some response, but it was balky. I could disassemble/reassemble and get 15-20 miles of it working, then it would die again.

I ordered a new sensor and Rad may eventually ship it. But placing the order let me be a bit more free and radical with my attempted fixes, and I did get it working reliably again by disassembling and scraping off the clear plastic which I had cracked. I've put over 150 miles on it now with flawless performance, so it seems it is working.
