A youth riding an electric bicycle and a car collided on Madison Street in Willowbrook, leaving the young rider in serious condition, police said.

The crash happened about 12:30 p.m. Thursday near the intersection of Madison and 71st streets, according to Patch, which published its report Nov. 10. The Willowbrook Police Department said the youth was transported for medical care and was in stable but serious condition.

Police released no other details.

The DuPage County MERIT Major Crash Reconstruction Team is helping with the investigation, police said. MERIT's crash team responds to fatal or serious-injury traffic crashes and uses specialized training to help the local agency complete a thorough investigation, according to the Village of Oak Brook's MERIT page.

The Metropolitan Emergency Response and Investigative Team, known as MERIT, is a countywide task force created in 2019. It leads investigations into serious crimes and critical incidents across DuPage County.

Madison Street was expected to remain closed while investigators processed the scene, according to the Willowbrook Police Department. Drivers were asked to avoid the area and seek alternate routes.

The collision comes as communities across the western suburbs have been tightening rules around electric bicycles and scooters. Hinsdale, Glen Ellyn and Lombard all require e-scooter riders to be at least 18 years old and limit motorized devices to roadways, ABC 7 reported in September 2025. Burr Ridge has banned e-scooters entirely and permits e-bikes only on village roadways.

A new Illinois law signed in August 2026 takes effect Jan. 1, 2027. According to the Darien Park District, the law requires operators to be at least 15 years old. Under current state law, riders must be at least 16 to operate a Class 3 e-bike, which can reach 28 mph, according to Ride Illinois. The Darien Park District separately banned motorized e-bikes, e-scooters and micromobility devices on all park district property effective Oct. 12, 2026.

It is not known what class of electric bicycle the youth was riding or whether any age or road-use regulations were a factor. No information about the driver or any citations has been released.
