E-Bike Injuries in Kids Are Rising Fast: What the New JAMA Study Means for Families

Remember the moment in E.T. when Elliott’s bike lifts off and crosses the full moon? Steven Spielberg needed an alien for that. Today a battery and a thumb throttle get a twelve-year-old surprisingly close to flying speed. The landing, unfortunately, still works the old-fashioned way.

A new study published in the journal JAMA on November 2, 2026, shows how quickly that is turning into a medical problem. Injuries from e-bikes among children and teenagers in the United States rose by 33 percent per quarter between early 2023 and March 2026. E-scooter injuries rose by 15 percent per quarter. Both curves climbed much faster than those for ordinary bikes and kick scooters.

What the JAMA study looked at

The research team, led by pediatrician Alan Schroeder of Stanford Medicine, analyzed medical records from six large U.S. pediatric health systems. The data came from PEDSnet, a network that pools electronic health records and is based at the Children’s Hospital of Philadelphia. The researchers included 13,307 patients under 18 who were treated for injuries involving e-bikes, regular bikes, e-scooters, nonmotorized scooters or skateboards in the period from January 1, 2023, to March 31, 2026. Specific diagnosis codes for e-bikes and e-scooters only exist since 2022, which is one reason solid multicenter numbers have been scarce until now.

The headline figure is the growth rate. Stanford describes the rise in electric injuries over the study period as exponential. All injury types went up, but the electric ones went up most.

Faster, heavier, more serious

The more worrying part is severity. Eight percent of injured e-bike riders had high-severity injuries, compared with four percent of riders on regular bikes. For e-scooters the figure was five percent, against two percent on nonmotorized scooters. The researchers counted things like ICU-level care, major injuries to the brain, chest, abdomen or neck, amputations and fractures that needed surgery.

Brain injuries were about twice as common with the electric versions: ten percent of e-bike patients and nine percent of e-scooter patients, compared with five and four percent for the pedal and kick versions. Seventeen percent of e-bike injuries led to a hospital stay, the highest share of any group in the study.

Age is another striking detail. About a quarter of the injured e-bike riders and almost half of the injured e-scooter riders were younger than 12.

Physics offers a simple explanation, though the study itself does not test it: more speed and more weight mean more energy in a crash. Some e-bikes can be pushed to speeds at which, as the authors warn, a regular bike helmet may not offer enough protection.

What the researchers recommend

Schroeder does not mince words. He called the findings “a serious public health emergency that needs a public health solution.” He also said he personally thinks children under 12 should not ride any form of motorized vehicle, which is his opinion rather than a result of the data. Coauthor Stephanie Chao, a pediatric trauma surgeon, pointed out that many parents do not realize e-bike riders might need different helmets than regular cyclists.

The authors’ wish list includes minimum ages for electric vehicles, speed limits on e-bikes, tamper-resistant speed controls that riders cannot easily override, fuller helmets suited to higher speeds and clear rules that treat e-bikes as part of traffic. Some California counties already set age limits for faster e-bikes. San Diego and Marin require riders to be at least 16.

The limits of the data

The study is a short research letter based on observational data. It has blind spots. It covers six hospital systems in the United States, so it cannot speak for every country. It only sees children who ended up in an emergency department, urgent care or hospital, so minor scrapes treated at home are missing. It does not report helmet use, road conditions or how fast anyone was riding. And because the e-bike codes are new, part of the increase could reflect doctors getting used to them. That caveat is ours, not one the authors raised in the published press material.

What the study does show clearly is a pattern that pediatric surgeons have been describing anecdotally for a while. Now it comes with numbers.

Why this matters beyond the U.S.

E-bikes and e-scooters are a lifestyle product as much as a vehicle. They are sold as the chic, green, effortless way through the city. Often they are. That is exactly why the numbers deserve attention: the same design that makes them fun for an adult commuter makes them risky for a light, inexperienced child.

If you are a parent, the study does not tell you to ban every wheel in the house. It suggests asking harder questions: How fast can this thing go? Can it be tuned? Is the helmet made for that speed? Are the local rules clear? Regulation in many places is still catching up with the technology. The authors argue it needs to move faster. Until it does, the most important safety feature is still the adult who decides which bike goes under the tree.
