Hi, I have a Speedbox 2 on a Bosch Active Line Plus bicycle running like a charm since 5000 kilometers.
Unfortunately since a few days I’m having a big problem when I switch ON the speedbox : when I go over 25km/h the speed displayed on the Purion screen changes constantly in an random way like 36…77…64…89…41… Also I can feel on the pedal that the power kicks in by very small input of 1 sec or so as long as I’m over 25.
The Speedbox seems now unusable, but the bikes operates normally when it’s off.
The only change I made on the bike is a tire replacement at the rear.
Do you have an idea on what might be the issue ? Any procedure to test or reset the Speedbox ?
Thanks a lot
