Park Tools makes bike stands that can support the weight of a heavy e-bike and the legs fold up to make it easy to store them when not in use. I paid $180 for their PCS-9.2 home mechanic bike repair stand and it was OK with a 70 lb e-bike but barely. I ended up selling the two 70 lb e-bikes and buying two Class II bikes that weigh 27 lbs and are a lot easier to manage.
