After a series of fires involving faulty e-bike batteries including a recent blaze that claimed four lives, New York City officials announced Sunday that they are receiving a $25 million emergency grant from the federal government to fund scores of charging stations citywide.

Mayor Eric Adams hopes the stations will provide a safer way for delivery workers, who rely on e-bikes to efficiently do their jobs, to recharge lithium batteries used to power their bicycles.

“This means that residents will no longer need to charge the e-bikes in their apartments — what we find to be extremely dangerous, particularly when you charge them overnight,” Adams said at a news conference Sunday. He was flanked by the state’s two U.S. senators who helped secure the funding from the US. Department of Transportation.
