Is there a particular model you are considering?

I do not have one of their E-Bike specific racks. I do like their racks Mine is a 4 place, I think it is the XTC4. It is heavy, appears well built. Not RV rated, but I use it on the back my TT. The older I get, the more I want a help handling to get it on/off the TT (commonly we leave it on the TT for extended periods).
Only thing that is a "pain" about it, is the shared center support (like the E-Spec Black model). If you are not thinking about it, it can be a pain to get it raised from a lowered position around the peddles.
I would have no issues buying another Swagman bike rack.
