Winter Cycling in Chicago: What to Wear, Ride and Expect

Chicago riders do not stop in January. Winter riding is easier than it looks, and just about any old bike will do if it has fenders and lights². The work is in the preparation. For the wider picture, start with the commuting guide.

Dress in three layers

Layering is the whole system. Active Transportation Alliance recommends three layers¹:

• Base: a thin polyester or wool fabric that wicks sweat. Avoid cotton¹.
• Middle: loose merino wool, fleece or synthetic fibers¹.
• Outer: a wind-resistant, water-resistant jacket, ideally with zippers and vents¹.

Cover the extremities. Wear a beanie or cap thin enough to fit under your helmet¹. Choose waterproof boots a half to full size larger than normal, so thick socks fit and toes move¹. Lobster gloves, or mittens over glove liners, keep your hands warm and still let you brake and shift¹.

Start slightly cold. If you feel warm at the door, you are overdressed. Sweat can freeze when you stop pedaling and raise the risk of frostbite¹.

Set up the bike

Fenders come first, since they keep slush off you and your bike¹. Regular tires work well unless heavy snow exceeds 3 inches¹. Wipe the bike down regularly and lubricate all moving parts except the brake pads¹.

Lights are not optional. At night a bicycle needs a white front lamp visible from at least 500 feet. A steady or flashing red light visible from 500 feet may be used in addition to or instead of the red reflector⁴. See Illinois bike light law.

Divvy is a winter option. Its bikes have built-in fenders, chain guards, lights and baskets, and you skip cleaning the chain². Compare plans on Divvy pricing.

Know who clears the lanes

Plowing is split. CDOT manages snow removal on roughly 70 miles of protected bike lanes. The Department of Streets and Sanitation plows mixed-traffic lanes and paint-only bike lanes³. After the early-December 2025 storm, which dropped eight to ten inches over a weekend, Streetsblog photographed protected lanes still snowbound days later, and one rider said snow forced him further into the street³.

Report a lane that needs attention through 311³. Choose your route with that in mind: main streets clear first but carry more traffic, while side streets hold more slush and snow but stay calmer¹.

Ride slowly on ice

On ice, hard-packed snow or slick metal, stay loose, pump the brakes, keep your weight back and go slow¹. If you start to slide, do not try to correct or brake. Stop pedaling and hold steady¹. There is no shame in walking your bike when you need to¹.

In very low temperatures, check the forecast, know your limits and keep an L station in mind as a backup².

Buy gear at the Winter Bike Swap

The Chicago Winter Bike Swap returns Sunday, February 14, 2027, in St. Charles, Illinois⁵. Adult admission is $8, kids 12 and under are free, and parking is free⁵. It is a cheap place to find a used commuter and winter gear before the worst of the season.

For year-round planning, see the Chicago bike lanes guide.
