Syncd-N, Scottsdale

"Unity in motion." That's the motto of SYNCD-N owners Howard and Dawn Lindsay, and it's not lip service—it's literal. That's because the husband-and-wife duo deal exclusively in tandem bicycles. "Riding a tandem bicycle requires a team to communicate thoroughly, to trust each other...and to lean on one another when one team member gets tired," they share on their website. This shines through in both their commitment to each other—which has been strengthened since they took up the sport—and to their customers, to whom they offer trial rides. The rides familiarize the customers with the skills necessary for navigating a bicycle together, from peddling in sync to leaning in the same direction in order to dodge puddles full of tears from lonely unicyclists.
