I believe part of the reason for the delay & resulting country exclusivity is due to needing a repair presence to support the bikes.
Speaking to an independent senior bike repairer, they told me that they’re unlikely to fix eBikes as they can be more complicated & once they touch a bike to repair the onus is on them to bring it to restore to a repaired state (ie if you pay for a repair and it’s not repaired then the fault will lay with them until corrected).
So unlike traditional bikes that largely are free & operate mechanically similarly, you’re more likely going to see a more electronic car-style repair model (eg where only Tesla are repairing Tesla cars) and a push to consolidation where the 3rd party bike manufacturers or parts (eg Bafang motors or no-name) will lose out to those who have a physical store & large network (Trek, Giant, etc).
I’d love someone’s opinion on this to validate or challenge the thinking here — as for now, it seems I’ll wait forever and never to get a Van Moof or Cowboy & importing seems a dead end since it wouldn’t be repairable by any local repairer.
