BROOKLYN - Brooklyn residents who have traded in their cars for bicycles say they are still facing one familiar problem: a lack of parking.

Commuters say navigating city streets by bike is challenging enough, but as more opt to ride on two wheels in light of high gas prices and jam-packed mass transit, safe parking spots have dwindled.

?I never leave my bike in the street because there's no place to lock it up,? says John Seder, who rides daily to his job in Borough Hall.

While the city says it is trying to be more biker-friendly and is installing dozens of biker shelters, Brooklyn Councilman David Yassky wants to take things a step further.

?A commercial office building has to allow bikes into the lobby and to go up on the elevator,? Yassky says.
