Thanks for the search source. It looks like that is more European based than USA based, but still a great source.
IMHO Shimano knows bikes better than Bosch or Yamaha. In my VW and Porsche days in the 70’s and maybe even into the 80’s Bosch electrical products seemed to have an edge in quality, but at a huge price. Starting in the 90’s on other electronic component producers seems to catch up and offer similar quality for much better prices. An electric bike is a bike first and electric assist second. Shimano seems to be yet another company that has been able to produce quality electronic components, while still keeping their bicycle components and experience top notch.
So far the Focus Jam2 line with Shimano STePS and Di2 option remains at the top of my list. Although I haven’t ridden one yet, from what I have read it has a bicycle (MTB) feel and Q-factor with the same quality suspension as their non-electric assist MTB’s.
Hoping to test ride one soon.
