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.
This looks so cool! But when I watch the video it almost looks like you have to lift the front end of the bike. I have a wagon. Think it would be doable for a strong female to do? :)
Mine is mounted such that it hangs with the rear tire about an inch off the ground. As such I can roll it in and the action of pushing it all the way into the rack "bumps" it up and into hanging.
I have seen people mount it higher so that you do have to lift but to me it seems that would defeat the purpose.
I do end up dragging the fender mud flap a bit as I roll my City. Don't know if the Wagon has anything like that which would interfere with you rolling it standing up on its back wheel.
