Sorry to hear about the issue you are having if possible get rid and buy a bike from a normal dealer I am sure online dealers are fine but once they have sold you a bike any issue to resolve is a nightmare. I like Canyon but would never touch due to the online issue and they are hardly any...
Personally I am totally addicted to ebikes and will never ride analogue again this was after a 20-min ride, so literally you are now able to walk the next day after a 30-mile ride:)
Spending that kind of money what about an Sworks Levo 2022 the spec is amazing seeing them with discounts for a while now just a thought. Also on vote what about none of the above and having suggestions.
I think things like this will always be a niche product just like Rohloff hubs, certainly is a great idea but all those moving part's is a recipe for disaster. Motors already means far too many bikes have to go back for warranty work, why add to the problem.
