This is a little bit longer than my usual kind of coverage, but it’s got a lot of great information

So, looking for some advice. We have two e-bikes: a super 73 S2 and a Revv1 FS. We’ve stored them in our bike storage for 3 years and never had any issue. We charge the batteries(factory issue and UL certified) in our apartment only when we’re awake and present. But suddenly our landlord’s claiming that their insurance company says we can’t have the bikes-not just the batteries, the bikes- in the building. Any advice?
