It took me some trial and error on finding a good bike rack for the EZ-1 I have. I came across the best deal at etrailer.com. It is hard to find a rack that will not take some effort to get the bike on, but this one is one of teh easiest in my opinion. Here is a pict of it on back of the Smart car.
This is the Swagman XTC2. It is the best bike rack I have had over the years. It was purchased at: https://www.etrailer.com/Hitch-Bike-...an/S64650.html
