Kudos to your shop for working on e-bikes at all. My experiences have been that bike shops/mechanics won't even do normal bike stuff, like working on brakes, when its an e-bike.
I had 3 simple questions to decide if an e-bike went in my stand:
1.) Does the frame use a seatpost?
2.) Are there any frayed or broken wires?
3.) Is the power cable to the motor removable?
I suppose the reason for needing a seatpost is to clamp on your stand. E-bikes get heavy, like 30kgs / 65lbs isn't at all rare, I wonder how if thats good for a seatpost?
Removable battery is as good as a removable power cable right?
Seatposts support hundreds of pounds of human flesh also, so the weight usually isn't the concern. But if your bike looks like more of a motorcycle, it's probably not going into my work stand.
On the point about the power cable, this is more directed at hub Drive motors. If I can't disconnect your motor to remove your wheel, I'm not going to fix your flat tire.
