LimeBike is the first dockless bike share to offer a cash program that allows riders to unlock their rides in their preferred method of payment. LimeBike’s rides cost $1, or $.50 cents for students, per 30-minute time block. Bikes are GPS and 3G-enabled, making it simple for riders to find, unlock and pick up a nearby bike using the iOS or Android smartphone app. When the ride is finished, riders simply lock the bike’s back wheel and responsibly park between the pedestrian-designated sidewalk and the street curb or at a bike rack. The dockless network makes it easier for DC residents and visitors to explore the whole city on two wheels. Since its launch, LimeBike has provided nearly 350,000 rides to more than 200,000 riders. This has saved over 120,000 pounds of CO2, the equivalent of over 6,200 gallons of gasoline in 17 markets. Read more at limebike.com.
