Motorcycle lifts as shown here have the capability of lifting the kind of weight you're talking about easily. But what they don't do is to get the wheels off the ground or off the bench so you can rotate them as you would normally do in tuning a bicycle or in this case an E bike. There's another issue too. I'm sure that there's ways to build a typical bike stand to handle the weight, but are you able to lift the bike onto the stand?
Would that work with a derrailler? How do you get the width right for different bikes? Somebody on the forum said they used car jack stands. I was thinking Aface could jack it up with one of the above jacks, then let it rest on car jack stands wherever they would fit, perhaps under the chain stays. I have the same sort of problem and I've taken to winching my bike's up into a small apple tree. I'm not sure the tree appreciates it much though.
I see a guy that has one of those welded to some type of thing in the middle of his small truck bed.
