70-year-old man on motorbike struck, killed in northern Warren County

A 70-year-old man riding a motorbike Monday evening who was struck and killed near Carlisle in northern Warren County has been identified.

David Landsaw was riding a motorbike south on Franklin-Madison Road when he was hit by a 2021 Chevrolet Blazer, according to the Ohio State Highway Patrol. Franklin Twp. Fire and EMS were performing CPR on Landsaw when troopers arrived. He was pronounced dead at the scene, according to a press release.

The crash happened around 6:30 p.m. on Franklin-Madison Road near Chamberlain Road about a half-mile from the Montgomery County line.

Landsaw was reportedly riding a bicycle that was modified with a small gas-powered motor to run the back wheel. He was headed south on Franklin-Madison Road when traffic was beginning to go around to pass him, said Sgt. Robert Burd of the Ohio State Highway Patrol’s Lebanon Post.

“Not knowing that he was being passed, the gentleman on the bicycle made a lefthand turn into traffic to go into a driveway and end up being struck by one of the vehicles passing,” Burd said.

The collision threw Landsaw from the bike, according to a press release.

The driver of the vehicle that struck the man is not at fault, the sergeant said.

The crash remains under investigation.

It is not clear whether the modified bike was street legal, nor whether the man, who was not wearing a safety helmet, would have been required to have a motorcycle endorsement for the bike.

Crews from multiple jurisdictions responded to the scene because the crash happened so close to the border and initially was reported by witnesses in the Germantown area.
