Bicycling advocates crow that some 86,000 people now bike to work every day in New York City — a 50 percent jump over 10 years ago. But while our politicians move heaven and asphalt to keep bike zealots happy, what have they done for the mere 3,599,786 New Yorkers (according to the most recent Census) who don’t bike to work?

They’ve made our commuting lives hell — the city, by making driving in Manhattan and parts of Brooklyn an even worse ordeal than it ever was; the state, by letting our subways rot.

Meanwhile, the city Department of Transportation cheerfully boasts of adding more bike lanes — some 600 miles of them today, soon to reach 1,000 miles. More spokes for the folks! Never mind that making room for them funnels motor vehicles through fewer lanes, making Midtown seem more auto-clogged than seven years ago even though there are actually 45,000 fewer daily cars today.

How did priorities get so warped?

Blame in large part our politicians’ fear of the fanatical biking lobby, which gave me a taste of their ugly tactics this week after a tongue-in-cheek, anti-bike-lane rant I made was posted online.

Some of my friends put up with street cycling’s risks for the joyful sense of exhilaration it brings. But despite obvious, visible increases in their numbers, it’s easy to lose sight of how relatively very few they are in relation to those who get around on foot, subway, bus and car.

The masses have not put their feet to the pedals in meaningful numbers, despite metastasizing lanes and the installation of 600 easy-to-use Citibike stands in 55 neighborhoods around town.

While the DOT insists that 2.5 percent of New Yorkers “commute” by bike, the most recent Census put the figure at less than 1 percent. Compared with 6 million daily subway users, DOT’s claim that 778,000 New Yorkers “ride a bicycle regularly” is a joke — the agency defines “regularly” as “several times a month.” The 25 percent said to “ride a bike” means anyone who’s done it once in the past year.

Yet the cycling-lobby tail wags the dog of rational city policy and planning. It started under former Mayor Michael Bloomberg, who after the defeat of his congestion-pricing plan in 2008, unleashed bike-mad DOT Commissioner Janette Sadik-Khan to rid the streets of cars by other means.

Mayor de Blasio, like Bloomberg, can’t stomach auto traffic on environmental grounds. Both pols used every trick in the book to make motoring in Manhattan even more difficult for those who don’t have chauffeured limousines at their beck and call.

But also, City Hall is scared to death of highly organized, militant, take-no-prisoners pro-biker cadres who dominate community board and other public hearings and heckle speakers — like campus hoodlums who ban or shout down speakers of whom they disapprove.

My over-the-top, anti-bike rant this week clearly wasn’t meant altogether literally — backdrops included comical collisions and bikes whizzing past me on a beach strewn with palm trees.

But Twitter-trolling began within minutes. Some were good-humored enough, considering that I said that as mayor, I’d tear up all the bike lanes “in the middle of the night” and “without warning.”

I chuckled at being called a “human paraquat,” an “old fart,” a “terrible human being,” “anti-NYC person” and a “dimwit’s dimwit” cursed with insufficient dietary fiber and a “micropenis.”

But just as many tweets reflected the movement’s ugly side. One guy would “laugh at the irony” if I got run over by a car. Biking-zealot group Brooklyn Spoke called me “racist” for once writing that Upper East Side bike lanes are the “superhighway for General Tso’s chicken” — a playful observation that the lanes are used mainly for home food deliveries.

One reprehensible theme was that people who show up at anti-bike-lane gatherings are mostly old. Such unapologetic ageism would be impermissible in any other debate. “Old,” it should be noted, evidently includes grim-faced, 30- and 40-something parents in my neighborhood who clutch their kids with both arms to protect them from red light-running, wrong-way bikers.

No mayor is likely to yank bike lanes in the middle of the night nor even day. But maybe the next mayor will have the guts not to add more of them at the expense of the 99 percent of us who prefer other ways to get to work.
