Very much so. My bike has a Bosch motor - even updates are done by remote control by Bosch employees and the shop can only adjust a few basic parameters.

Took me 2 weeks to get a fix that had my bike stop the electronic assistance at 18km/h instead of 25km/h.

Now it stops at 22-23km/h - but I just can’t be arsed to go through the process again.

Never Bosch again.
