A 36-year-old Brooklyn man was fatally struck by a charter bus driver in Chelsea on Monday morning as he biked along West 26th Street on a Citi Bike. Dan Hanegby, who lived in Brooklyn Heights with his wife and two children, became the first person to die riding a Citi Bike since the bike share program launched in 2013.

According to a preliminary NYPD investigation, shortly after 8 a.m. Hanegby was biking eastbound in the same direction as the 52-year-old bus driver. Between 7th and 8th Avenues, Hanegby "fell to the ground which resulted in the rear tires rolling over" him, the NYPD said in a statement. First responders found Hanegby on the street with "severe trauma to the body." He was transported to Bellevue Hospital, where he was pronounced dead.

Hanegby worked as director of investment banking at Credit Suisse. The NY Times reports that he moved to the U.S. from Israel in 2003 to study at Binghamton University and later transferred to Brown University— and that he was once the #1 ranked tennis player in Israel. Hanegby reportedly met his wife at age 10 when they were both practicing at the Israel Tennis Centers. From the Times:

Neighbors said that he was stoic and always focused and that he devoted his weekends to his children. They played at a nearby playground and spent time outside together. Steve Adams, who lives next door, said he saw Mr. Hanegby on weekends wearing cycling clothes and riding a racing bicycle. “That’s why it’s so weird, what happened with him falling,” Mr. Adams said. “Life is so strange.”

The operator of the bus remained at the scene and was not charged. A police source told DNAinfo that the bus driver and Hanegby "both swerved at the same time to avoid hitting something, causing them to strike each other." One warehouse worker in the neighborhood told the website, "The bus kept going at first and I ran after it. Then it put on the signal and pulled over."

Citi Bike has logged 43 million trips since it rolled out four years ago. In a statement, a Citi Bike spokesperson said, "This morning a rider on a Citi Bike bike was involved in a fatal crash. Together with the City of New York, we wish to express our heartfelt condolences to the rider’s family and loved ones on this terrible tragedy."

Some cyclists and safe streets advocates questioned the preliminary NYPD account of the fatal collision, which appeared in news reports such as NY1, which said Hanegby "collided with a charter bus and fell to the ground," suggesting Hanegby was at fault.

People on bikes don't collide with buses that are passing them safely. The victim deserves a real investigation, not stenography. https://t.co/orPrPD0Pph — Brooklyn Spoke (@BrooklynSpoke) June 13, 2017

In his daily Transportation Alternatives column, Bike Snob NYC writes: "Inasmuch as the victim was a trained athlete, experienced cyclist, and IDF sergeant, all of the above accounts imply a sort of haplessness on his part that seems spurious, and at the risk of jumping to conclusions this sounds a lot more like being sideswiped by a speeding bus. I suspect most of us have had harrowing encounters with these types of vehicles."

West 26th Street, a one way street, is not a designated truck route, and Bike Snob points out that the operator of a charter bus would only be allowed to use it for the purposes of arriving at his or her destination, according to NYC traffic rules.

Following the fatal collision, officers in the 10th Precinct, where Hanegby died, were reportedly issuing summonses to cyclists on Citi Bikes. (In April, soon after a truck driver killed a cyclist in the East Village, officers in the 9th Precinct pursued the same enforcement strategy, angering bikers and safe streets advocates.)

18 cyclists were killed in NYC traffic in 2016, which is more than the 14 killed in 2015. Hanegby becomes the fifth cyclist killed so far in 2017, according to city data.
