Lithium-ion batteries in electric bikes cause house fires.

Is it true that lithium-ion batteries in electric bikes cause house fires?

Partly. Official London Fire Brigade data indicates lithium-ion battery fires from e-bikes and e-scooters occur roughly every two days, often in homes while charging, and a government dataset lists lithium battery fires as a fast-growing risk. However, a skeptical analysis argues overall lithium-ion battery fire rates are extremely low, so the evidence only partially supports the claim that e-bike batteries cause house fires.
