Go this back from Haibike which is expected but disappointing
Morning Chris
Unfortunately, the warranty is only valid for the original purchaser and is not transferable or extendable.

Is this even legal? if you buy a second-hand car the warranty is with the date of registration and the car not the owner of the car so I do not see why it should be any different for a bike as long as you prove when it was first brought.
+1 Komoot - Best one I've tried for a phone app by far only minor issue I found was it sometimes takes you on footpaths but it seems to be a common issue on the apps.
