Communication is the key to a successful tandem team.
Have ridden with blind stokers, and it is a real treat; you can also describe the scenery, other cyclist, etc. to her as a 'visual' description.
Anything you plan to do while riding tandem you should communicate: pedal, coast, braking, shifting, stopping, etc. Stoker has the job of doing the hand signals: You, the pilot, voices: left turn, right turn, slowing, stopping . . . and she gives the proper hand signal.
Also call out the bumps and road hazards.
Communicate and U-2 will enjoy tandeming more!
Pedal on TWOgether!
