OP said he lives in a small apartment. I don't think building a concrete bunker is an option for him. There are over a million ebikes imported into the US every year. I think 1.7 million last year. Ebike fires are relatively rare. I found these interesting statistics on the People for Bikes website:
https://www.peopleforbikes.org/news/nyc-emobility-risks
Of the 53 reported e-bike fatalities nationwide from 2017 to 2022, 25 occurred in one of the five boroughs of New York City and two more occurred in neighboring cities in New Jersey. New York City had 47% of nationwide e-bike fatalities even though its residents only account for about 2.5% of the U.S. population.
Of the 40 deaths nationwide related to lithium-ion battery fires, 29 (72%) occurred in New York City alone.
According to
Underwriters Laboratories, deaths from e-bike fires declined in New York City after battery safety standards were written into law. At the same time, the number of fires and deaths rose rapidly from near zero prior to 2020 to a peak of hundreds of fires and 18 deaths in 2023. So far in 2024, only four people (still four too many) died from a battery-related fire in the city. This progress is no doubt due to the passage of ordinances that require lithium-ion batteries used in all e-mobility devices to be tested and certified by accredited third party laboratories, ongoing public education, and diligent enforcement efforts by the Department of Consumer and Worker Protection and the New York Fire Department, including shuttering some of the worst violators and going after online sellers who openly sell substandard batteries.
