A couple that recently moved to Pinellas County faces life-threatening injuries after they were hit on a tandem bicycle early Monday morning.

The couple was found at 6 a.m. Monday morning along Memorial Causeway in Clearwater.

The tandem bike the couple was riding was found in pieces.

Twenty-five year old Rob Lemon and 27-year-old Hilary Michalak were found several feet away.  It is not known how long the couple was injured on the side of the road.

Michalak was rushed to Bayfront Medical Center and is in critical condition.

Lemon is at St. Joseph's Medical Center in Tampa with life-threatening injuries.

Police say no evidence was left behind at the crash scene, and no one witnessed the accident. 

Michalak and Lemon moved to the area from Michigan earlier this summer. Michalak took a job as a Director of Youth and Families at Lutheran Church of the Good Shepherd Church. Lemon worked as a manager at Ride N Roll bike shop in Largo.

Owner of Ride N Roll Frank Lopez said Lemon recently purchased the tandem bike the couple was hit on, and was looking forward to teaching his girlfriend how to ride.

"She was skeptical because she had never ridden a bike as much as he did," Lopez said. "He was willing to invest the time and buy the tandem and get her to understand how much fun it is to be out there riding on the road."

Lopez said Lemon was known for his safety first approach to cycling. He said Lemon always wore a helmet and used safety lighting, even when trail riding.

Neighbors of the couple in Largo also say Lemon was safety-minded when riding. Chris Privitera said he saw the couple testing the tandem bike last month shortly after they bought it.

"I remember pulling in and I saw them riding it," Privitera said. “It was their first time and they were excited about it."

Clearwater Police say they have no leads in the investigation and are hoping witnesses come forward that may have seen the accident or the vehicle involved.
