About Your Current Bikes/Tandem If you are existing tandem riders then measure your tandem, or if it doesn't fit you very well then measure your solo bikes instead.

Choose a cycle that you ride that fits you really well; if you are thinking of a drop handlebar tandem for the front rider then measure a drop handlebar bike, and likewise if you are thinking of a flat handlebar tandem on the front then measure a flat handlebar bike.
