Illinois uses three classes and keeps access close to bicycle rules.
Illinois uses three classes of low-speed electric bicycle. Classes 1 and 2 stop assisting at 20 mph; class 3 is pedal assist to 28 mph. Every class must have fully operable pedals and an electric motor of less than 750 watts (625 ILCS 5/1-140.10).625 ILCS 5/1-140.10
The short answer
Roads and paths generally yes; sidewalks no
Qualifying e-bikes follow bicycle rules, may use bicycle-authorized roads and bicycle paths unless the path authority prohibits them, and may not be ridden on sidewalks. Class 3 operators must be at least 16. Driver-license, registration, insurance, and helmet answers are less explicit in the citeable HTML sources and are marked unclear below.625 ILCS 5/1-140.10 · 625 ILCS 5/11-1517
01 / Categories
Motor, pedals, and assisted speed set the class
Pedal assist · 20 mph
Class 1
It must have fully operable pedals, an electric motor of less than 750 watts, and the motor behavior and assistance cutoff for one of Illinois's three classes. Manufacturers and distributors must permanently label the class, top assisted speed, and motor wattage.625 ILCS 5/1-140.10 · 625 ILCS 5/11-1517
Pedal assist only, with motor assistance ending when the bicycle reaches 20 mph.625 ILCS 5/1-140.10
Throttle-capable · 20 mph
Class 2
The motor may propel the bicycle without pedaling, but cannot provide assistance when the bicycle reaches 20 mph.625 ILCS 5/1-140.10
Pedal assist · 28 mph
Class 3
Pedal assist only, with motor assistance ending when the bicycle reaches 28 mph.625 ILCS 5/1-140.10

Core consequence
Class 1
Pedal assist to 20 mph
No express minimum in the cited current section
Pedal assist to 20 mph; bicycle operating rules apply. It may use roads and bicycle lanes open to bicycles and bicycle paths unless the path authority prohibits its class, but it may not be ridden on a sidewalk.625 ILCS 5/1-140.10 · 625 ILCS 5/11-1517
Class 2
Throttle-capable to 20 mph
No express minimum in the cited current section
Throttle-capable to 20 mph; bicycle operating rules and the same road, path, and sidewalk rules apply. Its motor must disengage or stop when the brakes are applied.625 ILCS 5/1-140.10 · 625 ILCS 5/11-1517
Class 3
Pedal assist to 28 mph
Operator must be 16+
Pedal assist to 28 mph; operator age 16+; speedometer required. Bicycle operating rules and the same road, path, and sidewalk rules apply.625 ILCS 5/1-140.10 · 625 ILCS 5/11-1517
Next category unclear: it does not fit 625 ILCS 5/1-140.10's low-speed electric-bicycle definition, but the cited current statute does not assign one automatic replacement category or public-road answer to every nonconforming electric bicycle. Ask the Secretary of State about the exact vehicle before public-road use.625 ILCS 5/1-140.10
Age floor partly unclear: 625 ILCS 5/11-1517(h) expressly requires a class 3 operator to be at least 16. The current section states no minimum for class 1 or class 2 and does not expressly say that no minimum exists for those classes.625 ILCS 5/11-1517
Driver's license
No-license answer rests on statutory structure: 625 ILCS 5/1-146 excludes low-speed electric bicycles from the definition of motor vehicle, while § 6-101 requires a license to drive a motor vehicle. Neither cited section expressly says that a qualifying e-bike rider needs no driver's license, so the public answer remains unclear.625 ILCS 5/1-146 · 625 ILCS 5/6-101
Registration and title
No-registration answer rests on statutory structure: 625 ILCS 5/1-146 excludes low-speed electric bicycles from motor vehicles, while § 3-402 subjects motor vehicles to registration and title rules. The cited sections do not expressly say that a qualifying e-bike needs no registration or title, so this remains unclear.625 ILCS 5/1-146 · 625 ILCS 5/3-402
Liability insurance
No-insurance answer rests on statutory structure: 625 ILCS 5/1-146 excludes low-speed electric bicycles from motor vehicles, while § 7-601 requires liability insurance for a motor vehicle designed for public-highway use. Neither cited section expressly says that a qualifying e-bike needs no insurance, so this remains unclear.625 ILCS 5/1-146 · 625 ILCS 5/7-601
Helmet
Helmet rule unclear in citeable HTML: 625 ILCS 5/11-1517 sets e-bike equipment, labeling, access, and class 3 age rules but states no helmet requirement. The Secretary of State's express statewide helmet statement is available only in a PDF, which the evaluator cannot cite yet. Check local law and wear a helmet.625 ILCS 5/11-1517
General penalties
When the Illinois Vehicle Code provides no different penalty, a first or second conviction is a petty offense; a third or later conviction within one year after the first is a Class C misdemeanor (625 ILCS 5/16-104).625 ILCS 5/16-104
Adult answer remains unclear in this registry: the cited current e-bike section states no helmet requirement, but silence is not an express exemption. The Secretary of State's direct statewide answer is PDF-only and cannot support a cited claim until the evaluator can parse PDFs. Check local law and wear one anyway.625 ILCS 5/11-1517
04 / Where you can ride
Roads, sidewalks, paths, and trails use different rules
Roads and bicycle lanes
A qualifying e-bike may use any highway, street, or roadway authorized for bicycles, including bicycle lanes. The bicycle provisions of the Illinois Vehicle Code apply unless § 11-1517 provides otherwise.625 ILCS 5/11-1517
Bicycle paths and sidewalks
Yes by default under 625 ILCS 5/11-1517(f), but the municipality, county, or local authority controlling the path may prohibit all low-speed e-bikes or a specific class.625 ILCS 5/11-1517
No. 625 ILCS 5/11-1517(g) prohibits operating a low-speed electric bicycle on a sidewalk.625 ILCS 5/11-1517
Trails and IDNR property
On IDNR-owned, leased, or managed property, a bicycle or qualifying e-bike may use a roadway designated for vehicles, a parking lot, or a posted bicycle trail. The rule generally caps bicycle and e-bike speed at 20 mph on roads, paths, bicycle trails, and drives unless posted otherwise, and IDNR may close a trail for safety or resource protection (17 Ill. Adm. Code 110.165).17 Ill. Adm. Code 110.165
Blanket trail access is unclear: 625 ILCS 5/11-1517 expressly addresses bicycle paths, not every recreational or natural-surface trail. IDNR separately limits riding on its property to designated roadways, parking lots, and posted bicycle trails. Check the trail manager's current signs and rules.625 ILCS 5/11-1517 · 17 Ill. Adm.
