I had been using a wall hook (into the stud) to hang my RadCity vertically for out-of-the-way storage but the weight was killing me lifting it up and down.

I picked up a steadyrack fender rack (https://www.steadyrack.com/) and I endorse it heartily for heavy e-bikes. I can simply roll the bike into and out of it with no lifting which has saved my back. Check it out- it's great.
