Quick Answer
Federal law defines a low-speed electric bicycle in 15 U.S.C. 2085 as a two or three wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts, whose maximum speed on a paved level surface, when powered solely by the motor and ridden by an operator weighing 170 pounds, is less than twenty miles per hour. That definition puts the machine under the Consumer Product Safety Commission rather than under the federal vehicle safety standards. Here is the part that most e-bike articles get wrong about this state: Kentucky has not adopted the three class e-bike system, and there is no Kentucky statute assigning Class 1, Class 2 or Class 3 e-bikes to particular paths or trails. Nor is there a statewide bicycle helmet requirement for riders under eighteen that could be located in Kentucky’s traffic code. What Kentucky does have is KRS 189.287, which directs the Transportation Cabinet to promulgate administrative regulations setting standards for bicycle equipment and the safe operation of a bicycle, including lights, reflectors and audible warning devices.
Electrically powered bicycles are increasingly popular because they offer the freedom of a bike with an extra push from a motor. Riders are injured and killed because they, and the motorists around them, make mistakes and cause crashes. Collisions with motor vehicles are the leading known cause of death for e-bike riders, and that is the fact that should shape how a rider thinks about the road and about a claim.
What is an E-Bike?
The federal Consumer Product Safety Commission regulates the safety and sale of low-speed electric bicycles. Its own working description, in the staff report Micromobility Products-Related Deaths, Injuries, and Hazard Patterns: 2017 to 2021 published in September 2022, treats e-bikes as motorized bicycles powered by battery to assist a rider’s pedal power, with a maximum speed of 28 miles per hour. Read that against the statutory definition above and the tension is obvious: the 750 watt and twenty mile per hour figures in 15 U.S.C. 2085 describe what the statute covers, while the machines actually being sold and studied include faster ones.
The bicycle industry created a three tier classification to describe them, and it is worth knowing what those labels mean because you will see them on a spec sheet:
- Class 1: maximum assisted speed of 20 mph, with the motor providing power only when the rider pedals, known as pedal assist
- Class 2: maximum assisted speed of 20 mph, with the motor able to deliver power independently of the pedals
- Class 3: maximum assisted speed of 28 mph when the pedals and the motor are used together, marketed to commuters who travel farther than most cyclists would attempt
Those are manufacturer categories, not Kentucky legal categories. The CPSC does not use them, and neither does the Kentucky Revised Statutes. If a retailer or a rental company tells you a class label determines where you may legally ride in Kentucky, ask which statute says so.
What are State Laws Concerning E-Bikes?
This is the section that needs the most care, because Kentucky’s traffic code has a genuine gap here and pretending otherwise can cost a rider a case. KRS 189.010, the definitions section for the whole traffic chapter, contains no definition of an electric bicycle. The only electric micromobility device it defines is the electric low-speed scooter, described in KRS 189.010(26) as a device weighing less than one hundred pounds, equipped with wheels, handlebars and a brake adequate to stop and park it, designed to be stood or sat upon, propelled by an electric motor, human power or both, and designed to operate at a maximum speed of twenty miles per hour on a paved level surface. KRS 189.010(19)(b) then excludes both vehicles propelled by muscular power and electric low-speed scooters from the definition of a motor vehicle for traffic purposes.
So an ordinary bicycle is not a motor vehicle, and an electric low-speed scooter is not a motor vehicle, but an electric bicycle is not named at all. Whether a particular e-bike is treated as a bicycle, as an electric low-speed scooter, or as something else in Kentucky depends on its specifications and has not been settled by any statute we could open. We are not going to resolve that question on a blog page, and neither should anyone else. What it means practically is that a rider should not assume the rules that protect cyclists automatically reach an e-bike.
Those protections are real and specific. Under KRS 189.340(2)(a), a driver overtaking a bicycle or an electric low-speed scooter proceeding in the same direction must move to the immediate left lane where one is available and moving into it is reasonably safe, and where there is only one lane in that direction must pass at a distance of not less than three feet between any part of the vehicle and the bicycle, maintaining that distance until safely past. If three feet is not available, the driver must use reasonable caution. KRS 189.340(2)(b) lets a driver cross the center line, even in a marked no passing zone, to pass a bicycle or scooter, but only if the way is unobstructed for a sufficient distance. KRS 189.340(2)(c) provides that riders shall not ride more than two abreast in a single lane unless on a part of the roadway marked exclusively for bicycle use, and that two riding abreast shall not impede the normal and reasonable movement of traffic.
Local rules can also apply. KRS 189.287 exempts bicycles and riders that comply with the Transportation Cabinet’s regulations from municipal safety equipment rules, but expressly not from local rules on method of operation, so a city or a park authority can regulate how and where you ride even when your equipment is compliant. If you ride a particular trail regularly, the posted rules for that trail are worth reading.
How Dangerous Are E-Bikes?
The honest answer starts with a warning about the data. The National Transportation Safety Board devoted an entire study to it. Micromobility: Data Challenges Associated with Assessing the Prevalence and Risk of Electric Scooter and Electric Bicycle Fatalities and Injuries, safety research report SRR-22-01, dated November 14, 2022, found that police crash data have no e-bike device codes, that injury surveillance data have no e-bike specific coding, and that no trip data exist that would let anyone calculate a risk per mile ridden. In its own independent analysis the NTSB found at least 119 fatalities involving e-scooters or e-bikes combined in the United States between 2017 and 2021, and recommended that the National Highway Traffic Safety Administration, the Federal Highway Administration, the CPSC and others fix the coding gaps.
The CPSC staff report gives the other half. Across all micromobility products, estimated emergency department visits rose 127 percent from the 2017 estimate to the 2021 estimate, and rose 34 percent from 2020 to 2021, both statistically significant. But the e-bike specific estimates did not meet the reporting criteria for the National Electronic Injury Surveillance System for any year from 2017 through 2021 and are not published, because of small sample sizes and a high coefficient of variation. CPSC staff put e-bikes’ share of all micromobility emergency department injuries at about 11 percent over the five years. Anyone quoting you a precise national e-bike emergency room count for that period is quoting a number the agency declined to publish.
The fatality side is firmer. CPSC staff identified 129 micromobility fatalities from 2017 through 2021, of which 53 involved e-bikes, rising from none in 2017 to 6 in 2018, 6 in 2019, 18 in 2020 and 23 in 2021. Reviewing those 53 deaths, staff found that collisions with motor vehicles were the leading cause, accounting for 27 of them. Twelve were user control incidents such as striking a fixed object or a curb, six involved pedestrians, and seven were falls with insufficient information to determine a cause. Both reports carry caveats worth stating: the CPSC document is a staff report that has not been reviewed or accepted by the Commission, and CPSC noted that fatality reporting for 2020 and 2021 was still ongoing.
The clinical picture comes from peer reviewed work rather than a press interview. DiMaggio CJ, Bukur M, Wall SP, Frangos SG, Wen AY, Injuries associated with electric-powered bikes and scooters: analysis of US consumer product data, Injury Prevention 2020;26(6):524 to 528 analyzed national injury surveillance data from 2000 through 2017 and found that compared with people injured on pedal bicycles, people injured on e-bikes were more likely to suffer internal injuries, 17.1 percent of cases, and were about 2.8 times as likely to be hospitalized. It also found e-bike collisions with pedestrians were more than three times as likely as with pedal bicycles, and that e-bike injuries rose over the study period, particularly among older adults, while pedal bicycle injury rates fell. In injury pattern, then, an e-bike crash sits closer to a motorcycle crash than to a bicycle crash.
One more hazard the original version of this page did not mention, and it is the one CPSC investigators actually found. Of eleven completed in depth e-bike investigations, fire hazards and brake problems were identified in eight. A lithium battery fire in a garage or a hallway is a product liability and premises problem as much as a traffic problem, and it produces burn injuries rather than crash injuries.
What’s Causing These Accidents and Injuries?
Older riders may have slower reaction times and do not recover as quickly, and the published research is consistent with that concern: the 2020 analysis above found e-bike injuries rising particularly among older adults. Younger riders can be poor judges of risk and may not understand how much irresponsible riding raises it, whether that is running stop signs or red lights, riding too fast, using a phone while riding, or moving into vehicle lanes.
Kentucky’s rules of the road reach some of that conduct directly. Under KRS 189.330(1), where two vehicles approach an intersection from different roadways at approximately the same time, the operator on the left yields to the vehicle on the right, and KRS 189.330(4) requires a driver approaching a stop sign to stop and then yield to any vehicle in the intersection or approaching so closely as to constitute an immediate hazard. Under KRS 189.290(1), the operator of any vehicle upon a highway must operate it in a careful manner with regard for the safety and convenience of pedestrians and other vehicles. Under KRS 189.570(6)(d), a driver must exercise due care to avoid colliding with any pedestrian, sound the horn when necessary, and take proper precaution on observing a child or an obviously confused or incapacitated person on a roadway, which is the rule that matters when an e-bike rider is the one who strikes someone on a shared path.
Some riders modify their machines so they exceed the speeds they were built for. The physics of that are not controversial: brakes, tires and frames specified for one speed do not become adequate at a much higher one, and a motor that outruns the braking system is a defect the rider created. We are not going to name a manufacturer or repeat a claim that a particular model caused particular deaths, because those are contested allegations and this is not the place to resolve them. What matters legally is that a modification is evidence. If an e-bike was altered before a crash, that alteration will be the first thing the other side’s lawyer looks for, and if a component failed on an unmodified machine, the purchase records and the firmware history are what prove it.
Add drivers who are unaccustomed to sharing the road with e-bikes, or who simply drive badly, and you have a genuinely dangerous mix.
The Deadline and the Coverage Question
If a car struck you, the claim arises out of the operation of a motor vehicle, and the Kentucky deadline is the two year period in KRS 304.39-230(6), running from the injury, the death, or the date of issuance of the last basic or added reparation payment, whichever occurs later. That is longer than the one year period in KRS 413.140(1)(a) that governs personal injury actions generally, so which rule applies is not an academic question.
The tort limits are where the classification gap bites. Under KRS 304.39-060(2)(c), Kentucky’s no fault tort limitations do not apply to a person who is not an owner, operator, maintainer or user of a motor vehicle. A pedal cyclist plainly fits that description, because a bicycle is not a motor vehicle. Whether an e-bike rider fits it depends on whether the e-bike is a motor vehicle under KRS 304.39-020(7), which covers vehicles that transport persons or property upon the public highways propelled by other than muscular power, subject to listed exclusions including mopeds and electric low-speed scooters. We could not find a Kentucky statute or a decision we could read that answers that for an e-bike, so we are telling you it is unresolved rather than picking the answer we would prefer. It matters, because if the limits do apply, the threshold in KRS 304.39-060(2)(b) restricts recovery for pain and suffering unless medical expense exceeds $1,000 or the injury involves permanent disfigurement, a bone fracture, loss of a body member, permanent injury within reasonable medical probability, permanent loss of a bodily function, or death.
Two more rules apply either way. Under KRS 446.070, a person injured by the violation of any statute may recover from the offender the damages sustained by reason of the violation, although a penalty is also imposed, which is how a driver’s failure to give three feet under KRS 189.340(2)(a) becomes part of a civil case, subject to proving that the violation caused the harm. And under KRS 411.182 the fact finder assigns each party a percentage of the total fault and each party is liable only for its own equitable share, so a rider who did something unwise does not automatically lose, and does not get to collect the whole judgment from one defendant either.
Hurt on an E-Bike in Kentucky? The Rules Are Not Settled, and That Cuts Both Ways
An e-bike claim in Kentucky is unusual because the vehicle itself has no legal category here. That uncertainty is used against riders routinely, in arguments that a rider was an unlicensed motor vehicle operator, that the three foot passing rule never applied, or that the no fault threshold bars pain and suffering. Those are arguments, not answers, and they should be answered with the specification sheet, the motor rating, the firmware settings and the statutory text rather than with assumptions. The Fleck Firm, PLLC was founded by attorney Tyler M. Fleck, a U.S. Army veteran who built his practice to serve people throughout Kentucky. If a driver hit you while you were riding, or a battery or brake failure put you in the hospital, we will preserve the machine before anyone crushes it, document its motor rating and any modification, identify whether the case is a traffic claim, a product claim or both, and protect the deadline that applies. We will also tell you honestly which parts of Kentucky law are unsettled here, because a lawyer who claims certainty on this subject is guessing. The first consultation is free and we work on a contingency fee, so there is no fee unless we win for you.
