Mayor Zohran Mamdani said Wednesday that New York City has sent cease-and-desist letters to more than 40 online retailers, including Amazon, Best Buy, Walmart, Target and Wayfair, demanding they immediately stop selling e-bikes and motorized scooters that exceed the city’s legal speed and power limits. The retailers have until August 18 to comply or face civil penalties of up to $2,000 for each infraction.

Mamdani announced the letters at a press conference on Center Street in Lower Manhattan, steps from where a 17-year-old was killed one week earlier. Gabriel Nacato was riding a Deep Power QS7 e-bike from Bensonhurst into Manhattan to meet a career counselor and fill out summer job applications when he was struck by an SUV coming off the Brooklyn Bridge, the mayor said. The bike is capable of reaching more than 30 miles per hour.

“Gabriel should still be with us today,” Mamdani said. “He should be submitting his summer job applications and practicing for an upcoming interview.”
