A perv sexually assaulted a young girl riding her bike in Queens, cops said today.

The sicko lured the 11-year-old victim towards him around 6:30 p.m. on Oct. 1 at Broadway and Whitney Avenue in Elmhurst by asking her if she could help him fix his black mountain bike, cops said.

The creep groped the child, who was then able to escape, cops said.

The suspect is described as a white man, between 35- and 45 years-old, and about 6’2” tall, cops said. He was riding a black mountain bike with a black seat and red stripes.
