I use a kayak lift system when I need to get my bike off the ground. I can raise it however high I need it and for most things, including cleaning, it works great. It was pretty inexpensive and easy to install in my garage. I raise the hooks out of the way when I don't need it. However I would like to see someone come up with a center stand that could be placed in the space behind the motor at the fender spacer/chain stay area. Not permanently attached to the bike but something you could use in the garage to securely keep the bike upright and allow the removal of the front or rear wheel in case of a flat. I am sure that many of you who do your own work found out the hard way just how heavy the rear wheel assembly is on bikes with the envolio hub. DR
ModernBIKE.com carries this stand. It is called a FeedBack sports Pro-Elite. I have been using it to work with the Rush/City Speed. It can handle the bike to some degree. I mention that caveat, because the clasp that is used to adjust the height of the bicycle being supported, slides down to its lowest setting when suspending the Rush/City Speed. Otherwise, it is a good stand that is strong and light weight When not in use, it folds up and stows neatly in a carrying case.
The Bikehand stand came a few days ago, and it's a winner. It is heavy duty. I got the bike up and secured, took off the rear wheel, got a new heavy duty tube installed, put the wheel back on. Good to go again. Got the bike cleaned up like new while up on the stand. It folded up nice, then stashed it in the garage.
