I have a Trek Powerfly 7 with Bosch CX Performance Line 85Nm motor and Kiox display. Overall I’m very satisfied with it. On Sunday I gave it a serious wash after one of our usual very wet and muddy rides, including slicing out around the clogged up motor housing by removing the shield and squirting water from a plastic drinks bottle - no hosepipes or pressure washers!
When I came to ride the bike to the pub that evening, on reinstalling the battery - taken out to clean contacts and casing - I got error code 500 (internal motor error) on the Kiox display and the motor was dead. The Kiox would still cycle through the drive modes but there was no power assistance whatsoever. I assumed water had got into the motor somehow so sprayed everything with WD40 and hoped for the best, preparing to make a warranty claim when the dealer opened on Monday morning.
Next day the bike powered up as normal and rode perfectly, the error 500 message had gone. Great, I thought, it’s dried out, but as it is still under warranty I rang the dealer and arranged to book it in for diagnostics, just in case of any future issues.
Yesterday I rode it the 14 miles to the Chichester eBike-centre for its checkup. They cleared the fault code and gave it a clean bill of health. There was no sign of water ingress or any kind of motor damage, so my cleaning regime was ok. Their conclusion on the fault was this:
I also asked the Technician about the value of adding any additional mud shielding to the motor housing, but was advised against it. He said these motors can get very hot internallyand any reduction in airflow that a shield might create would not be helpful.
Hope this might help someone else, sometime.

- I had probably removed the battery while the Kiox was still powered on.
- The Kiox has an internal battery which then went flat while the main battery was off the bike.
- On replacing the main battery the Kiox couldn’t talk to the motor so threw up the fault code 500 (internal motor error).
- The Kiox recharged itself overnight so in the morning all was back to normal. If I’d waited a little longer the previous evening it might well have restored itself then.
