Fires are being caused by e-bikes or e-scooters in London "every other day", a fire chief has warned after a fire left 11 people needing hospital treatment in Bethnal Green, east London, last week.
London Fire Brigade (LFB) chiefs believe the fire was caused by the failure of a lithium-ion battery.
Richard Field, dep ass commissioner for prevention and protection at LFB, said e-bikes and e-scooters were one of the capital's "fastest-growing fire risks".
"Since 2023, we have seen a fire, on average, every other day and these fires are ferocious, producing extremely toxic smoke," he said.
Many recent fires have involved second-hand e-bikes or e-scooters which have been modified using parts bought online which do not meet the correct safety standard, Mr Field added.
The Bethnal Green fire on 9 April saw 50 people evacuated after it spread through the block in Cornwall Avenue.
One man jumped from a second-floor window to escape the flames but was unhurt.
Mr Field said: "This would have been a terrifying ordeal for all those inside this building.
"Firefighters demonstrated great courage to bring multiple people, including one child, to safety.
"The condition of one of the 11 people taken to hospital is no longer life-threatening."
