Queens cyclists will get a chance to celebrate their borough this Sunday during the first annual Tour de Queens bike ride.

More than 700 bicycle enthusiasts are expected to participate in the free 20-mile ride, which will start and end at the Queens Museum in Flushing Meadows-Corona Park.

Transportation Alternatives has sponsored similar events in Brooklyn and the Bronx.

About 3,000 cyclists participated in the fourth annual Tour de Brooklyn last month. And about 5,000 people cycle through the Bronx every fall in the Tour de Bronx.

"This is about building a biking community in Queens - getting people biking on their own streets, in their own neighborhoods with safer than usual conditions," said Wiley Norvell of Transportation Alternatives.

"We're hoping that once people come out on the tour, they will be converted."

The nonprofit group encourages cycling, walking and public transportation as more healthy and environmentally friendly ways to get around the city.

Transportation Alternatives works with city officials and local community boards to designate bike routes, off-street greenway paths and bike lanes.

"We hope people will see biking as not just recreation, but also as a way they can travel to work or to get groceries," Norvell said.

The ride will pass through several neighborhoods, including East Elmhurst, Astoria, Queensbridge, Long Island City, Maspeth, Middle Village, Rego Park and Forest Hills.

"The area around Forest Hills and Forest Park is one of the most beautiful places to bike in New York City," Norvell said. "Jackson Heights also has some great streets for biking."

Riders can take a rest stop at Queensbridge Park along the East River for a snack or a chance to take in a waterfront vista of Manhattan.

Astoria and Long Island City have fast-growing bike communities, said Norvell, who added, "On weekends, one in five vehicles in those neighborhoods is a bicycle."

There will be limited registration at 8 a.m. on Sunday.
