Uber’s boss says he’s bent on expanding into bike-sharing — despite the fact that it’s peanuts compared to the car-sharing business and Uber will be pedaling uphill in New York City.

Chief Executive Dara Khosrowshahi said last weekend that Uber is determined to master alternative forms of transportation, including bikes and scooters, even if it hurts the bottom line.

“Short-term financially, maybe it’s not a win for us, but strategically, long-term we think that is exactly where we want to head,” Khosrowshahi said in an interview published by the Financial Times. “During rush hour, it is very inefficient for a one-ton hulk of metal to take one person 10 blocks.”

When it comes to bikes in New York, however, Uber looks blocked out of Manhattan and most all of the affluent neighborhoods in Brooklyn and Queens.

That’s because archrival Lyft scooped up Citi Bike’s operator Motivate — which has an exclusive agreement with the city to serve those key neighborhoods for the next decade — in a surprise deal last month that was reportedly worth $250 million.

As such, some critics say Uber looks foolish for shelling out $200 million in April to buy Brooklyn-based electric-bike maker Jump, which is only allowed to operate in far-flung neighborhoods like Flushing and Brighton Beach, in addition to Staten Island and The Bronx.

“We will continue to work together with cities to help get more people on bikes,” an Uber spokesperson said when asked about the situation.

Meanwhile, Uber faces a cap on the number of cars it can put on New York streets, which Mayor Bill de Blasio imposed earlier this month.
