Fired up over safety
With lithium-ion batteries among the top causes of fatal fires in New York, Peter Donaldson talks to a company set on making e-bikes less risky
It only takes a few minutes on the internet to realise there is a big safety problem with e-bike batteries. Even a basic search for ‘e-bike battery fire statistics’ yields alarming numbers, press reports, government recommendations and official statements, such as the London Fire Brigade’s (LFB) recent declaration that e-bikes and e-scooters are now the city’s fastest growing fire risk.
