Plenty of cities have bike share programs: pay-as-you-go bikes that riders check out from a docking station, ride wherever, and then return to any open station. Now, dockless bike-share systems are rolling out in the U.S.

While these bikes have the same goal as their predecessor—to offer a quick, cheap means of traveling between transit hubs and riders’ final destinations—they feature one major difference: no docking station needed.
