Just because they’re homeless doesn’t mean they can’t have spinning classes.

A Manhattan comedian yesterday recruited a ragtag crew off the street to take advantage of an unintended bonus of the Citi Bike program — the pedals work even when the bicycles are docked.

Fabrizio “The Fat Jew” Goldstein led an impromptu SoulCycle class at a dock near Tompkins Square Park and put video of it online. Pedaling furiously, he yells, “You guys feeling the burn?” as Katy Perry’s “Firework” blares.

“I want the homeless people of New York to have the opportunity to have sick bodies,” he explains afterward.
