What Makes a Bicycle Class 3
Fla. Stat. § 316.003(23)(c) defines a “Class 3 electric bicycle” as one “equipped with a motor that provides assistance only when the rider is pedaling and that ceases to provide assistance when the electric bicycle reaches the speed of 28 miles per hour.”
Structurally it is Class 1 with a higher ceiling. There is no throttle — the motor assists only while the rider pedals, exactly as in Class 1 — and the general requirements of § 316.003(23) still apply: fully operable pedals, a seat or saddle, and a motor of less than 750 watts.
The 28 mph figure is the point at which the motor stops contributing, not a speed limit. A Class 3 machine ridden downhill may exceed it without leaving its class. Equally, a Class 3 rider on the flat is doing real work — the motor is assisting a rider who is pedaling, not carrying one who is not.
Where the State and Federal Tests Diverge
This is the most misunderstood point about Class 3, and getting it right matters for product claims.
Florida measures assisted speed: under § 316.003(23)(c), assistance ceases at 28 mph. The federal definition measures something else entirely. 15 U.S.C. § 2085(b) defines a “low-speed electric bicycle” by its “maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds” — and requires that figure to be less than 20 mph.
| Scheme | What It Measures |
|---|---|
| Florida — § 316.003(23)(c) | Assisted speed. Motor plus rider. Cut-off at 28 mph. |
| Federal — 15 U.S.C. § 2085(b) | Motor-only speed, with a 170-pound rider, under 20 mph. |
Because Class 3 assistance requires pedaling, a Class 3 machine's motor-only speed can easily fall below the federal threshold. A bicycle can therefore carry a Florida Class 3 label and still be a federal low-speed electric bicycle. The two schemes are not in conflict; they are asking different questions.
That is not academic. 16 C.F.R. § 1512.2(a)(2) brings such machines inside the CPSC definition of “bicycle,” and Fla. Stat. § 316.20655(5) requires an electric bicycle to comply with 16 C.F.R. part 1512 as a matter of Florida law — including the braking requirements at § 1512.5, which set a stopping distance no greater than 4.57 m (15 ft) from the test speed under (b)(1). Those obligations attach to the product regardless of the state class on the sticker.

What the Higher Speed Actually Changes
It does not change the duties owed to you. Fla. Stat. § 316.083(2) and (3) require a driver overtaking “the bicycle or other nonmotorized vehicle or electric bicycle” to pass at not less than 3 feet, without reference to class. § 316.20655(1) gives every e-bike operator a bicycle rider's rights and duties. § 316.151(1)(a)2. requires a driver turning right past a bicycle to do so only if the bicycle is at least 20 feet from the intersection and at a distance from which the turn can safely be made — a condition that speaks directly to a faster machine.
What it changes is the physics and the argument. A rider arriving at 28 mph reaches a junction sooner than a driver's experience of cyclists predicts, which is the mechanism behind many right-hook and left-cross collisions. Expect a defense to argue that the speed was unreasonable for the conditions.
Two answers to that. The 28 mph figure is an assistance cut-off, not evidence that the rider was traveling at 28 mph. And the misjudgement of closing distance is the turning driver's to make — § 316.122 requires them to yield to any vehicle “so close thereto as to constitute an immediate hazard,” and making that judgment wrongly is the breach rather than an excuse for one.
Lighting takes on extra weight at this speed. § 316.2065(7) requires, between sunset and sunrise, a white front lamp visible at 500 feet and a rear lamp and reflector each visible at 600 feet. The rear needs both.

Where Class 3 Machines Get Restricted
State law does not distinguish by class: § 316.20655(7) permits riding “where bicycles are allowed,” and no subsection of § 316.20655 treats Class 3 differently.
Local government does. § 316.20655(1) preserves local authority over operation on streets and sidewalks, and the authority of a municipality, county, or state agency with jurisdiction over a bicycle path, multiuse path, or trail network to restrict or prohibit e-bikes — along with beaches and dunes under § 161.54(3) and (4). Where a jurisdiction distinguishes, Class 3 machines are commonly excluded from shared-use paths on speed grounds, even though they are pedal-assist.
Since ch. 2025-149, § 316.20655(8) also permits local minimum age requirements and government-issued photo identification requirements. As always, the controlling text is the municipal code where you ride, not the statute. See where e-bikes may be ridden, and photograph the classification label required by § 316.20655(3) — on a Class 3 machine it is frequently the fact in dispute.
