I consider myself lucky to have experienced the original moped craze first hand, and now the current ebike situation.
1, both largely unregulated for now (until the bodies start to pile up), there could be a big crackdown coming.
2. there will be a huge "shake out" as many manufacturers/importers will fold
3. many are being sold by shops that have no idea how to fix them
4. Cops simply don't know what to do with the ebikes (like mopeds in the beginning), some choose to ignore them from what I see.
on & on.....
