Aslef, the RMT and the TSSA union are all demanding that the rules are changed to ban battery-powered bikes from the London Underground after
a catastrophic incident was narrowly averted at a Tube station last month.
The incident, at Rayners Lane station, saw an e-bike explode on a platform shortly before it would have been taken on board a Metropolitan line train.
A London Underground investigation concluded that if the explosion had happened on board the train, the outcome would have been much more severe.
The TSSA, which represents station staff, said its health and safety reps walked out of a meeting with Tube managers on Tuesday after they refused to instigate an immediate ban on the bikes.
TfL says it is acting on
London Fire Brigade advice and still considering the evidence, but the TSSA believes that an immediate temporary ban should be enforced, pending the outcome of a wider review of the fire risk.
Aslef, which represents Tube drivers, has warned that it may consider strike action. The TSSA says that it may also ballot its members on taking industrial action.
According to the London Fire Brigade, three people have died in house fires caused by e-bike battery failures in London since 2023 and more than 100 people have been hurt.
There were 143 e-bike fires in London in 2023, 142 last year and 14 in January 2025.
The RMT has been calling for a ban on taking e-bikes on the Tube since 2023.
A fire on a District line train in 2021 that was caused by an e-scooter battery exploding resulted in e-scooters and e-unicycles being banned from the Tube.
TfL said it had “factored in” the apparent increased risk posed by second-hand e-bikes and those with modified batteries to its risk assessments.
