Transport for London (TfL) has announced a sweeping ban on all non-foldable e-bikes across the majority of its services, effective from 31 March 2025, following safety concerns sparked by recent battery fires.

The move comes after a comprehensive safety review conducted in partnership with the London Fire Brigade, prompted by incidents of e-bike batteries catching fire on the transport system, including a notable blaze at Rayners Lane station in February.

The ban will apply to the London Underground, Overground, Elizabeth line, and Docklands Light Railway (DLR), and includes standard bicycles retrofitted with electric conversion kits. While most e-bikes were found to be safe, TfL cited difficulties distinguishing between modified and factory-built models as a key reason for the blanket restriction.

Union Pressure and Fire Risks

The announcement follows pressure from ASLEF, the train drivers’ union, which had threatened strike action if e-bikes weren’t banned following the Rayners Lane incident. TfL noted that cycles adapted with electronic conversion kits pose a higher fire risk than those manufactured as e-bikes due to inconsistent battery and charger standards.

Statement from the Mayor

Mayor of London Sadiq Khan supported the decision, saying:

“The safety of Londoners is my top priority. While most e-bikes are safe, a small number of non-foldable e-bike fires have caused me great concern.”

TfL’s chief safety officer, Lilli Matson, echoed the sentiment:

“Our priority is always the safety of our customers and colleagues. We’ve worked closely with the London Fire Brigade, and this ban reflects the seriousness of the risks involved.”

Fire Brigade Welcomes Ban

Charlie Pugsley, Deputy Commissioner for Prevention, Protection and Policy at the London Fire Brigade, welcomed the move:

“It acknowledges the risks that we know e-bike batteries can pose. We continue to call for improved safety standards across the industry.”

Impact and Exceptions

The ban will apply to:

• London Underground
• London Overground
• Elizabeth line
• Docklands Light Railway (DLR)

Non-folding e-bikes are already not permitted on buses or trams, and no e-bikes at all are allowed on the IFS Cloud Cable Car, a policy that will remain unchanged.

Foldable e-bikes that meet TfL’s size and weight restrictions will still be allowed.

TfL says the ban will remain in place until improved product safety standards are introduced for e-bike batteries, conversion kits, and chargers.

Passengers are advised to check TfL’s website for updated travel information and guidance before travelling with any electric or folding cycles.
