Ordered the motow ebike rack for about $500. Really wanted to like this rack, but it does not work for the ride 1 up 700st. The rack interferes with the centrally mounted kick stand and the chain. It also is very hard to mount with the rack and scratches the rack easily. So returned it. I'm posting this others do not make the same costly mistake. Bought a fulltyme 1300 rack from Walmart for $119. Very solid. Although you do need an adapter bike bar for step through. It is a Hollywood style hitch rack. Took it on its maiden 150 mile trip and it performed flawlessly.
Thx for the update. Not sure how this could interfere with a kick stand or chain though? This supports the wheels from inside the tyre rim and the bottom of the wheel. Was it the wheel bottom support arms? Happen to have any pictures? I do agree that when moving the inner bike from the outside position to the inside position you have to be careful, especially if you don't have a lot of room between the spokes. I had some left over adhesive neoprene squares that I cut down and wrapped around the rack arms and cradles to provide additional protection after seeing a couple of marks on my wife's bike/rack.
I also recently received an email from them stating that they are sending our replacement straps for the lower cradles as apparently there have been reports of failures. Haven't received the straps though yet.
