Chicago’s bike share program will kick off in June when the city debuts hundreds of light blue, three-speed bicycles that can be rented for an hourly fee or with a yearly $75 membership.

Managed by Portland, OR–based Alta Bicycle Share, which also runs New York and DC’s bike share, Chicago’s program goes by the name “Divvy.” Alta was supposed to launch the $22 million program last summer, and has since become the subject of controversy. Chicago Transportation Commissioner Gabe Klein was formerly a consultant for the company, and competitors have alleged foul play, which Alta and the city have flatly denied.

The first of Divvy’s 75 solar-powered docking stations will be downtown and in River North. Within a year the city’s plan is to roll out 400 stations and about 4,000 bicycles across the city.
