A 26-year-old Bronx man was struck and killed by a car while riding his bicycle in the borough just after midnight Saturday morning. 

Giovanni Nin, of Freeman Avenue, was found with severe injuries when officers arrived at East Tremont and Mayflower Avenues. He was later pronounced dead at the scene. 

The driver left the scene of the crash, police said. Investigators said they believe Nin was riding South along East Tremont Avenue when he tried to cross the street mid-block and was struck by the car. 

Authorities described the vehicle as a silver BMX X5, likely a model between 2000 and 2003. 

Police continue to investigate.
