I’d rather purchase a quality Kit and battery then purchase a rebranded bicycle that is built in a country that has a ban on them.
You do know that there are plenty of companies that make quality built e-bikes that aren't rebranded. Bosch is one that comes to mind frequently though I am sure there are some that get rebranded from the same parent company to fill a spot in all of their brands with the same bike, but that bike in the end is still quality because it is Bosch. Also you do have say the Cervelo mountain bike which is just a rebranded Santa Cruz...curious what the opinion on that is?
