A man on a motorized bicycle died after he struck a car in the city’s west-end Thursday afternoon.

The collision happened at Rockcliffe Blvd. and Alliance Ave. near Jane St. and Woolner Ave.

Emergency Medical Service officials said the man, described as approximately 40 years old, was taken on an emergency run to a Toronto trauma centre just after 4:30 p.m. with life-threatening injuries.

He succumbed to his injuries minutes later.

Alcohol may have been a factor for the driver of the bike, said Const. Clinton Stibbe.

The car’s driver, a 26-year-old woman, won’t face any charges, Traffic Services confirmed.

Police haven’t identified the man but say he is well known in the area for his gas-powered bicycle.

“It’s one of those grey area bikes, it’s not exactly a moped, but technically a modified bike,” Stibbe said. With the small engine utilized, the bicycle could reach an estimated maximum speed of 42 km/hour.

Gas-powered bicycles aren’t illegal, but Stibbe said they’re not recommended for Toronto streets.

Police are seeking the public’s help in identifying the victim.

The two occupants of the car were also taken to hospital with minor injuries.
