Solo is easy...learning to ride tandem takes some give and take from the teacher and the student. Tandems do ride faster than single bikes but require coordination, balance, thought and getting tired and dirty...But, the fun is learning to work together...Sure, maybe some drop down knockout arguments...But, in the end a team no one can beat...and one that always wins...Obviously, if you are not confident, openminded, willing to learn new things or push yourself out of your comfort zone...It's never going to work...
