Kids Biking Rules in Chicago: Sidewalks, Age Limits and Gear

The Chicago rule that matters most for children is the sidewalk rule, and its cutoff is age 12.¹ This page gathers that rule, the age limits on e-bikes, the rules on carrying a child, and the official guidance for riding with kids.

The sidewalk rule

Municipal Code section 9-52-020 sets two sidewalk rules, one for business streets and one for any sidewalk along a roadway.¹ Subsection (b) is the one that names an age:

“a person 12 or more years of age may ride a bicycle upon any sidewalk along any roadway only if such sidewalk has been officially designated and marked as a bicycle route” — Municipal Code of Chicago 9-52-020(b)¹

The sentence continues with the exceptions. A rider may also use the sidewalk to enter the nearest roadway, intersection or designated bicycle path, or to reach a bikeshare station.¹ On a business street, subsection (a) applies the same limits to every rider, regardless of age.¹

One stretch has its own rule. No person 12 or older may ride a bicycle on the sidewalk next to North Sheridan Road between West Ardmore Avenue and West Sheridan Road at 6400 north.³ A rider 18 or older who violates it faces a $200 fine, and only where the required signs are posted.³

Bicycles are barred from Lake Shore Drive and from any public way where signs prohibit them.¹

The state adds its own sidewalk duties. A person riding on a sidewalk has the rights and duties of a pedestrian, must yield to pedestrians and must give an audible signal before passing.⁹ Chicago repeats the yield-and-signal rule.¹⁰ The Secretary of State says the same: slow down, sound a bell or horn, and go around pedestrians when possible.⁶

E-bikes and age

Age limits on electric bikes are firm. Only a person 16 or older may operate a Class 3 low-speed e-bike, under the Chicago code and the state statute alike.^2,7 A person under 16 may ride only as a passenger on a Class 3 designed to carry one.⁷ No low-speed e-bike may be operated on a sidewalk.⁷ See Illinois e-bike laws for the classes.

Carrying a child

State law limits who rides and how. A bicycle may not carry more people than the number it is designed and equipped for, with one exception: an adult rider may carry a child securely attached to the body in a back pack or sling.⁸ In Chicago parks, the Park District Code adds that no one may carry a second person on the handlebars, frame or fender except in a suitable attached seat.¹¹

The Secretary of State’s booklet fills in the practice:

• A child should not ride or be carried on a bike or a trailer until sitting upright while supporting the weight of the head and helmet.⁶
• Child seats should not be used for kids over 40 pounds.⁶
• A trailer sits low to the ground, so use a flag to increase visibility.⁶
• In some places, carrying a child under 12 months old on a bike is illegal, so check local laws.⁶

Teaching and group rides

The booklet puts responsibility on the adult. Parents and guardians should be aware of their duties when children ride, from selecting equipment to teaching traffic laws.⁶

Fit comes first. A child should be able to straddle the top bar of the frame comfortably while standing flat-footed. A child learning to ride should be able to sit on the seat and put both feet flat on the ground.⁶

On a family ride, the booklet gives a formation. Ride in a single file line, with adults behind and slightly to the left of the children.⁶ For sidewalks versus street, it advises checking the local required age to ride in the street. If you ride with a child on the sidewalk, ride on the street beside them.⁶ The Secretary of State also states that a helmet can reduce the risk of head injury by up to 85%.⁶ The helmet law has its own page: the Illinois helmet law. On the road, see also riding two abreast.

Free classes

The Chicago Department of Transportation runs Learn to Ride through its SAFE Ambassadors. CDOT’s April 2026 announcement set classes for children aged 6 to 12 in partnership with the Park District. Classes run nine weeks, from June 17 to August 6, in Portage Park, Humboldt Park, McKinley Park and Washington Park.⁵ Parents must provide a working, appropriately sized bike. The Ambassadors provide and custom-fit a free helmet for every child. Each class can accommodate 8 children, and parents must stay onsite.⁵

Adults and teens aged 13 to 17 may join the separate adult and teen series, and teens must be accompanied by a parent or guardian.⁵ That series is offered in English and Spanish.⁵

What a violation costs

Chicago’s bicycle chapter sets a fine of $50 to $200 per offense unless another penalty is given.⁴ Section 9-52-021 names its own $200 penalty for adults on the Sheridan Road sidewalk.³
