I'm pretty happy that my bikes (MTB and Road) have zero electric components (not even light if I don't strap it on) and I want to keep it that way. I have yet so see an electric part that I need or that even just provides me with enough benefit that it's worth the hassle of freakin' firware updates. Much less having a CAN bus on my bike? is this only for electric bikes or also for gears? I'm confused...
Anyhow, I always thought that running a bike repair shop might be my plan B for when I finally get fed up with computers, but I recently realized bikes are now computers with wheels, just like cars and fridges and toasters and door bells... So I'm looking for a new plan B.
FWIW, just as with fridges and toasters, I think this is a move in the wrong direction. It increases CO2/pollution footprint and reduces lifetime. And as we see here, it opens you up to a whole new class of customer abuse.
