Solex, Puch, Spree, etc. all come to mind when I watch the video. Just a different flavor of moped, that's all. A long, long time ago the shop I worked in took on Solex to see what kind of extra numbers they were able to add to the bottom line. One year and we were out of it. Needed a small engine repair person on staff and there was not enough profit to permit it.
I imagine the e-bikes and e-mopeds will get to the same place, a tech on staff that is able to work on them in an efficient manner. Could be a gold mine in the right community.
