Just spotted this posting ! On my 9.8 XT which will be a year old at the end of July, I had no problem with the Kiox until I travelled across to Elan Valley mid Wales refitted the Kiox after the journey and it wouldn’t switch on…kept trying the on/off switch and bingo it came to life and I was able to complete my ride. This was early in May, bike into Blazing Bikes my LBS who are JUST GREAT! , assuming just a new Kiox …and after a check on the Bosch motor they replaced the motor and the Kiox under warranty.. I did an earlier post linking my Trek bike experience with Landrover Jaguar cars great to drive/ride , but have a terrible reputation when it comes to reliability statistics.. I hope I’ve just been a bit unlucky!!
