New Yorkers can ride Citi Bike in Manhattan, Brooklyn and Queens, but now the company that runs the program is making a major push to bring it to the Bronx and Staten Island.

Citi Bike operator Motivate wants to add 6,000 more bikes, with two-thirds of them going to neighborhoods that are not currently served.

But Motivate is trying to figure out a way to expand without needing taxpayer money.

Some ideas reportedly being considered are giving Motivate exclusive rights to bike sharing in the city, along with eliminating the fees the company pays the city.

"We all know we want to get to a five-borough system. We want to do it in a way that's going to be safe and efficient. I think we want to minimize taxpayer investment to the extent that we can," said City Transportation Commissioner Polly Trottenberg.

Citi Bike says it's the only bike share program in the world to operate without any public money.
