Tandems allow you to cycle together and enjoy the great bike routes of Sonoma Wine Country. They're also great for improving those communication skills! The stronger rider controls the gears, steering, and braking from the front seat, while the second rider helps to pedal from behind.
Keep in mind that both riders will need to be pedaling at the same time, and your turns will be a lot wider than on a regular bike. Having two people pedaling the uphills sure makes a difference, though!
