The morning air in Scottsdale tastes like dust and citrus—the Sonoran sun lifting off the pavement as your group assembles in front of a low brown building with “segway” stenciled on the window. Your guide fits a helmet and hands out a lightweight audio headset; the e-bike hums to life beneath you. Within minutes you’re gliding on the Greenbelt, a world-class paved path that threads lakes, palm-lined fairways and canals. Camelback and the jagged ridges of the McDowell and Mummy Mountains hold court on the horizon as the city shrinks into a patchwork of water and manicured green.
