E-bikes and e-scooters in Illinois: what’s actually legal

The short answer

Where each machine stands on a US road today.

The numbers that decide it

Illinois’s current e-bike classes and the incoming Giannoulias micromobility law (625 ILCS 5/11-1517).

E-bikes, in detail — today’s rules

Illinois currently uses the standard three-class system (625 ILCS 5/11-1517): Class 1 pedal-assist to 20mph, Class 2 adds a throttle to 20mph, Class 3 pedal-assist to 28mph, all capped at 750W.

• E-bikes are banned from sidewalks statewide (§11-1517(g)) — a hard rule with no built-in local exception, stricter than most states covered here.
• Class 3 riders must be 16+; no statewide minimum currently exists for Class 1 or 2.
• No statewide helmet mandate for any age or class — though this is exactly the kind of gap municipalities are filling locally (see below).
• A permanent class label is required on the frame, and altering the motor or speed without updating it is a violation (§11-1517(c)).

What changes 1 January 2027

Senate Bill 3484 — the “Giannoulias micromobility law,” championed by the Illinois Secretary of State and passed unanimously in the Senate (absorbing the earlier SB 3336) — creates the state’s first comprehensive framework for higher-powered devices:

• A new statewide minimum age of 15 for Class 1 and Class 2 e-bikes, on top of the existing Class 3 age-16 rule.
• High-speed micromobility devices — e-scooters, electric skateboards, electric unicycles capable of over 28mph — are barred from exceeding that speed on roads, bike lanes, paths, and sidewalks, and riders must be 16+.
• E-bikes and e-motos purchased before the effective date are exempt from titling but must still be registered — a transitional grandfather clause worth knowing if you’re buying now versus after the cutover.
• The law is explicitly intended to replace the current patchwork of wildly different local ordinances with one statewide standard — though as the section below shows, that patchwork is currently very real.

The suburban Chicago patchwork, right now

Until the 2027 law takes effect, individual municipalities — especially in suburban Cook, Lake, and DuPage counties — have been setting their own, often contradictory, e-bike rules:

• Harwood Heights and neighbouring Norridge have banned e-bikes entirely from streets, sidewalks, parks, and parking lots — a flat prohibition, not just a speed or class restriction.
• Schaumburg requires riders to be 16 on any e-bike; Elk Grove Village sets 15 for Class 1/2 (matching the coming state standard early).
• Glencoe requires a helmet at any age on Class 3 and bans Class 3 from village bike paths entirely.
• Palatine bars e-bikes from the Palatine Trail, without distinguishing compliant e-bikes from higher-powered “e-motos.”
• Fines escalate fast in some villages — a second violation can mean a $150 fine and impoundment; further violations $350-750 plus impoundment.

If you live in or plan to ride through suburban Chicago, check the specific village or city ordinance before you buy — the state baseline may simply not apply where you are.

The e-bike trap: continuous vs peak watts

The single most common e-bike buying mistake — and it applies directly to the federal 750W line.

US federal law (15 U.S.C. § 2085) measures continuous rated power — what the motor sustains, which must be 750W or less for the bike to qualify as a “low-speed electric bicycle” at all. But that’s rarely the number marketing leads with; sellers advertise peak power, a brief burst that can be double or more. A “750W” bike with a 1,500W peak rating can be perfectly legal — the continuous figure is what the statute measures.

Ask the seller for the continuous rating in writing, and look for a permanent manufacturer’s label on the frame showing the class number, top assisted speed, and motor wattage — required in most states that have adopted the three-class system, and your best evidence of compliance if ever questioned.

What it costs

Penalty structures are set locally and vary sharply — the figures above are examples from specific Chicago suburbs, not a statewide standard.

Before you hand over the money

• Check your specific suburb before buying if you’re in the Chicago metro area — Harwood Heights and Norridge ban e-bikes outright; others set their own age and helmet rules well ahead of the 2027 state law.
• If buying before 1 January 2027, note the grandfather clause: your e-bike/e-moto will be exempt from titling but still needs registration once the new law takes effect.
• Remember the sidewalk ban is statewide and absolute for e-bikes — there’s no built-in local exception to look for.
• For a minor, check both the current state age (16 for Class 3 only) and any local ordinance — several suburbs already require 15 or 16 for every class, ahead of the 2027 statewide change.
• Distinguish e-bikes from e-motos. Anything over 750W or without full pedal function is a different, more heavily regulated category under Illinois law.
