If your travel tandem is a Comotion, then your couplers are in front of the captain’s seat tube and outside of the drivetrain. That makes it quick and easy to disconnect the front triangle and reconnect. I do this with our Speedster all the time, and it takes less than 5 minutes, probably less than putting it onto our rack. We have a Chevy Bolt, which is small, but I put down the rear seats and open the rear hatch, then slide the bike in backwards on its side with the front wheel and triangle hanging out the back. Then I undo the 3 cable connectors and 3 couplers, then lay the front triangle onto the rest of the bike which has been covered by a blanket. Then close the hatch. With practice this takes about 3 minutes.
