We always try to get the bike inside the vehicle when we have a remote ride start.
For around town, I use the hitch-mount
Performance Flatbed. To make it work with the tandem I ordered the
Sport Rider Long Wheel Base Kit from Hollywood Racks. I like the flatbed racks because they are very easy to load and unload the bike(s). They also hold the bike securely without any chance of paint becoming marred from rubbing.
