It is probably safe to say that in the history of bill signings by governors in the State of New York, few, if any, featured the entrance that Gov. Andrew M. Cuomo made on Monday.
Mr. Cuomo arrived at Citi Field in Queens with his companion, the celebrity chef Sandra Lee, on the back of his Harley-Davidson motorcycle. As they arrived, groups of leather-vested bikers — “How you doing, brother?” one said — leaned in to shake the governor’s hand.
They were not exactly the Hells Angels pulling in, with a coterie of State Police, and other official vehicles escorting them from a park on Long Island and commandeering a highway lane to keep the pair safe.
But then, this was no hell ride. It was a publicity motorcycle tour aimed at increasing awareness for breast cancer screenings, and to promote a new piece of legislation that Mr. Cuomo signed into law at the Citi Field appearance. The law would mitigate hurdles for women seeking mammograms.
Mr. Cuomo hopped off his Harley-Davidson and doffed his helmet and windbreaker. He was dressed in a pair of khakis and a white golf shirt, looking more like a soccer dad than biker dude.
Mr. Joel looked slightly more edgy. The piano man was more or less dressed, to borrow a lyric from his “Scenes From an Italian Restaurant,” in engineer boots, a leather jacket and tight bluejeans.
While Mr. Cuomo and Ms. Lee, a survivor of breast cancer, headed to the news conference, Mr. Joel hung back, his motorcycle helmet now replaced with a New York Mets cap, befitting the location, which is the home of the Mets.
Mr. Joel took a quick cigarette break — perhaps the only hard-core biker aspect of the morning appearance — and between drags, obliged some construction workers and bikers seeking autographs.
The governor doubled back to collect Mr. Joel, who stole a last puff and then headed to his seat on the risers. He took the podium and praised the legislation as a good bill but added with a pun, “Everyone is telling me what a good Bill I am.”
Then Ms. Lee spoke, calling breast cancer “a very special kind of hell,” and praising Mr. Cuomo for his work on the legislation, which requires more than 200 hospitals and other health centers to expand their hours to offer mammograms, and would ban out-of-pocket costs for mammograms.
Mr. Cuomo took the podium and poignantly recounted his family rallying around Ms. Lee during her harrowing battle with breast cancer. She was given a diagnosis of breast cancer in March 2015 and underwent a double mastectomy soon afterward and has been declared free of cancer.
“She has taken a negative and she has, through strength of character, found a way to turn it into a positive,” he said.
With Mr. Joel standing behind him, the governor signed the legislation and then returned to his black 2001 Harley-Davidson Electra Glide Ultra Classic. The motorcycle is similar to the type used by his state troopers, but outfitted for more leisure use, with hard travel cases and a double seat.
The motorcycle bore the New York State flag on its front fairing, or windscreen, along with the printed number 56, a reference to his being the 56th governor of New York. His license plate was a solitary number: “1.”
Over the past few years, Mr. Cuomo has kept a very public friendship with Mr. Joel, whose motorcycle featured a gas tank emblazoned with an old State Police logo. The motorcycle was a Kawasaki that underwent a “retro-restoration” to look like an older State Police cruiser, Mr. Joel said, when asked about it by a group of bikers and construction workers sizing it up as Mr. Joel hopped on.
Mr. Joel, who was riding with a friend, headed back to Long Island, leaving Mr. Cuomo to continue the ride on Monday to appearances at Bear Mountain State Park and New Paltz, N.Y., in Ulster County. Mr. Cuomo is scheduled to resume the bike tour on two dates this month, crossing the state and finishing in Buffalo.
The governor pulled on a pair of goggles and a black helmet, and he and Ms. Lee hopped on the bike. Ms. Lee flashed a peace sign, Mr. Cuomo hit the gas and they were on the road again.
