Incident location, Long Island
What Happened
A 10-year-old boy from Holbrook was thrown from his e-bike and seriously injured Thursday night after being struck by a Porsche SUV on Patchogue-Holbrook Road in Lake Ronkonkoma, according to Suffolk County Police. The crash occurred at approximately 8:30 p.m. and sent the child to Stony Brook University Hospital, where he was treated for injuries police described as serious.
Newsday identified the injured boy as Mason Mereroa, 10, of Holbrook. According to a Suffolk County Police Department news release cited by Newsday, Mason was riding a 2025 e-bike northbound in the southbound shoulder service lane of Patchogue-Holbrook Road when he was struck by a southbound 2020 Porsche Macan. The Porsche was in the process of making a right turn onto Richard Place at the time of the collision. The direction Mason was traveling — north, in what is designated as a southbound shoulder service lane — placed him in a lane oriented against the general flow of traffic on that side of the road.
The impact was forceful enough to eject Mason from the e-bike entirely. Suffolk County Police stated in their news release that Mason was “thrown from the e-bike” as a result of the collision, a detail first reported by Newsday. Emergency responders transported him to Stony Brook University Hospital, where he was admitted for treatment of serious injuries. Police did not elaborate on the specific nature or extent of those injuries in their public release.
The driver of the 2020 Porsche Macan was not injured in the crash, according to police. Authorities noted that the driver remained on scene following the collision — a detail relevant to any subsequent investigation. As of the time of reporting, Suffolk County Police had not filed any charges against the driver. News 12 Long Island also confirmed that the child was thrown from the bike after colliding with the SUV, corroborating the details in the official police news release.
In the aftermath of the crash, law enforcement took both vehicles into custody. The 2020 Porsche Macan and the 2025 e-bike were impounded by Suffolk County Police for safety checks, a standard procedure in crashes of this severity that allows investigators to examine the mechanical condition of the vehicles and determine whether any equipment failures contributed to the collision. The safety check process can take days and may inform the department’s decision on whether to pursue charges or issue traffic summonses.
Police did not release information regarding speed, weather conditions at the time of the crash, or whether any additional factors — such as lighting, road surface conditions, or mechanical issues — may have contributed to the collision. The investigation was described as ongoing.
Location & Road Context
Patchogue-Holbrook Road is a busy commercial and residential corridor running through central Suffolk County, connecting the communities of Holbrook and Lake Ronkonkoma among others. The stretch where this crash occurred — in the service lane near the Richard Place intersection — is a section of roadway that features parallel service lanes alongside the main travel lanes, a common design on Long Island’s higher-volume arterial roads intended to manage local access and reduce conflict with through traffic. Service lanes of this type can create ambiguity about direction of travel and right-of-way, particularly for younger or less experienced riders.
The crash occurred at night, at 8:30 p.m., in what would have been diminishing or absent daylight depending on conditions.

Investigation & Legal Proceedings
As of the morning of Friday, May 22, 2026, no charges had been filed against the driver of the 2020 Porsche Macan, according to Newsday. The driver remained at the scene following the crash, which is typically a significant factor in how law enforcement and prosecutors evaluate potential charges. Suffolk County Police impounded both the Porsche and the 2025 e-bike for safety inspections, a step that can take days to complete and whose findings may influence whether any traffic violations or criminal charges are ultimately pursued.
The incident remains under active investigation by Suffolk County Police. No arraignment information, summonses, or additional legal proceedings had been publicly reported as of the time of publication. Newsday noted this is a developing story and pledged to update coverage as more information becomes available.
Broader Impact
This crash arrives at a moment of heightened scrutiny around e-bike use — and access by minors — across Long Island. Just days before the collision, Newsday reported that the Town of Smithtown moved to ban e-bikes and e-scooters from parks and beaches, a sign of the growing tension between the proliferation of electric micromobility devices and questions about where and by whom they can be safely operated. A 10-year-old riding a 2025 e-bike northbound in a southbound service lane at night encapsulates many of the concerns driving that policy conversation: age-appropriate access to higher-powered bikes, directional safety in service lane environments, and visibility after dark.
