A 14-year-old boy was killed Tuesday evening after his electric motorcycle went down a flight of stairs inside the I‑5 Colonnade mountain-bike skills park in Seattle’s Eastlake neighborhood. Medics arrived to find the teen with severe head and body injuries, and he was pronounced dead at the scene. Police said he had been wearing a bicycle helmet at the time of the crash.

According to KOMO News, dispatchers received a call just after 6 p.m. reporting that the youth had been injured while riding an electric motorcycle down a flight of stairs in the park. Seattle police responded, and medics attempted life-saving measures, but the rider did not survive.

A Seattle Fire spokesperson told Capitol Hill Seattle that crews rendered aid at the scene but the rider died of his injuries, and that Seattle Police and the King County Medical Examiner were on site to investigate. The crash was reported to have occurred entirely within the bike park and did not involve any other vehicle. The I‑5 Colonnade sits under Interstate 5 between Capitol Hill and Eastlake and includes a pump track and skills lines, according to Seattle Parks.

New State Rules Add A Safety Angle

Washington recently tightened how it classifies electric bikes versus more powerful electric rides, a change that has added a regulatory backdrop to crashes involving young riders. As KIRO 7 reported, a law that took effect June 11 designates any electric-assist vehicle capable of exceeding 20 mph on motor power alone as an electric motorcycle. That triggers licensing and registration requirements and can limit use by riders under 16.

Investigation And Response

According to Capitol Hill Seattle, Seattle Police said the department is investigating the crash and that the King County Medical Examiner was at the scene to determine the cause of death. Chaplains and other on-scene support were requested as crews worked the incident, which local riders say has been at a popular spot for young people since a recent pump-track overhaul.

Safety Takeaways

Public-health and injury experts note that heavier, faster electric machines raise the risk of severe crashes and that helmets, while essential, cannot prevent all catastrophic injuries. The Harborview Injury Prevention & Research Center outlines e-bike classifications and recommends proper helmet fit, choosing safer routes, and checking whether a vehicle is legally a bicycle or a motor vehicle so riders follow the appropriate safety and licensing rules.
