Kirkland police say the victim was riding to work around 3 a.m. in the 13200 block of NE 124th Street when he was struck near an intersection. Officers say the SUV continued for a block, then turned around and returned to the scene.
Medics were called, but the rider was pronounced dead when they arrived.
Police arrested the driver of the SUV for investigation of DUI, and they were also interviewing a passenger, officials said. Neither were hurt in the crash.
Investigators say the crash happened despite the bicyclist wearing all the correct gear to make him visible, including a reflective vest, head lamp and blinking lights.
"The bicyclist was doing everything right, he was well marked with lights and everything," said Lt. Mike Murray with Kirkland police. "(The driver) is under arrest for investigation of DUI at this time."
The intersection of NE 124th St and 132nd Ave NE was closed for several hours during the investigation.
The victim's name not been released.
