Daniel Byrd, 21, of the 2100 block of Spring Street, was arrested in connection with the July 28th theft.
It happened around 4:30 a.m. that day behind the Irish Pub at 20th and Walnut, which was the starting point for the Tour de Shore ride.
Riders had been storing their bikes there before the ride.
Surveillance video captured a light-colored Ford pickup truck as it drove up to the scene.
A person, later identified as Byrd, was seen getting out, stealing the 15 bicycles, and driving away.
That video was released to the media two days later and, police say, several tips followed.
Byrd was then identified as the suspect and he was arrested on Wednesday.
Byrd is charged with theft, criminal trespass and related offenses.
