Bike Parking Downtown Chicago: Racks, Corrals and Locking

Downtown Chicago parks bikes the way it always has: on the street, at a rack, with a good lock. Indoor storage is rarer than it was, and the biggest public option is gone. This page covers what is left and how to use it.

Street racks and corrals

The city has installed over 15,000 public bike racks and over 80 on-street bike corrals.¹ Businesses and developers have added thousands more through ordinance.¹ The Bike Parking Program has set an annual goal of installing hundreds of racks since 1993.¹

The standard is the galvanized steel inverted U rack.¹ A corral holds 10 or more bicycles in the space a single car would take.¹

To find a rack near your destination, use the city’s bike rack data set, which lists locations and can be viewed, printed or downloaded.³ If a spot is missing, residents can request a rack through the CDOT Bike Parking Request Form, after which the Bike Parking Manager visits the site to check placement.¹ Businesses and developers follow a separate request path.¹

Parking at CTA stations

Racks stand outside most L stations, and many stations add sheltered outdoor or indoor bike parking for security and weather protection.⁴ If your commute is a ride to the train, the rack at the station is usually your parking. The riding side of that trip is in the bike commuting guide, and the on-board rules are in bikes on CTA trains.

How to lock

The city’s theft-prevention guidance is short and specific.²

• Lock the frame and wheels with a high-quality, modern U-lock.²
• Take lights, bags and quick-release parts with you.²
• Use a bike rack, or a parking meter or sign pole firmly affixed with bolts covered in concrete.²
• If the wheels are quick-release, lock through the frame and a wheel, then add a cable or second U-lock for the other wheel.²
• Lock even for a moment.²

Avoid “sucker poles,” sign posts loosely bolted down that can be lifted off. Avoid private property.²

Record the serial number, keep a photo of yourself with the bike and keep the receipt. Register the bike with the Chicago Police Department.² If it is stolen, file a report at a district headquarters or through 311, then file on the Chicago Stolen Bike Registry.² The full routine is in bike locks in Chicago and bike theft in Chicago.

Parking for a full workday

A bike left eight hours or more needs secure parking and a great lock or locks.⁷ Active Trans has talked with the Building Owners and Managers Association and the city about covered, secure parking at large downtown office buildings. The association leaves the decision to the market, and many buildings do not provide it.⁷ Ask your building manager before you ride, and see bike-friendly buildings.

The Millennium Park bike station

The largest public indoor option downtown was the Millennium Park bike station at 239 E. Randolph St. It opened in 2004 with indoor bike parking, locker rooms, repair and rentals.⁵ When Shift Transit took over operations in 2021, it listed 244 indoor spaces, 100 outdoor spaces and 92 lockers.⁵

It did not last. The station closed permanently on September 30, 2022, and in 2023 the city said the building was being converted solely into a police facility.⁶ The full story is in the station history. For anything you need from it today, use the racks above and the commuting hub.
