@joriki @ryansingel I had an email exchange with Larry vs. Harry (Bullitt) about why they use Shimano motors and offer no Bosch ones. Turns out the main reason is that Shimano is committed to keeping the mount points constant, but Bosch mount points have sometimes changed between motor generations, so newer motors cannot always be mounted into earlier frames.

@szakib @joriki @ryansingel I had no idea about this, thanks for sharing that detail!

@bluejekyll @szakib @joriki @ryansingel I didn’t know that, either (and I’m on my second Bullitt). I think the Shimano motors are better anyway. 😄

@marcprecipice @bluejekyll @joriki @ryansingel I originally asked this question because my bike mechanic friend's informal stats say that the Bosch motors have better build quality and they are more reliable.
But even with more frequent repairs, I expect the Shimanos to be more cost-efficient in terms of total cost of ownership over the years. (Does anyone have data on this?)
What is it that you like more about the Shimanos?
