The rapid rise of electric bikes and scooters across the UK has brought undeniable convenience, affordability, and environmental benefits. But alongside this surge in popularity, a dangerous trend is accelerating at an alarming pace: record-breaking fires linked to e-bikes and e-scooters.
In 2025 alone, the uk news24x7 recorded at least 432 e-bike fires and 147 e-scooter fires, marking the highest figures ever documented. These numbers represent a 38% increase for e-bikes and a 20% rise for e-scooters compared to the previous year—clear evidence that the problem is not only growing, but intensifying rapidly.
The Alarming Rise: A Record-Breaking Year
The numbers behind the surge are stark and impossible to ignore.
- 432 e-bike fires in 2025 (up from 313 in 2024)
- 147 e-scooter fires in 2025 (up from 123 in 2024)
- More than fivefold increase in e-bike fires since 2021
London remains the epicentre of the crisis.The London Fire Brigade reported:
- 206 total incidents in 2025
- 171 e-bike fires and 35 e-scooter fires
- Fires occurring every other day on average
This dramatic increase highlights a troubling reality: the adoption of electric mobility has outpaced safety awareness and regulation.
Why Are E-Bike and E-Scooter Fires Increasing?
1. Lithium-Ion Battery Failures
At the core of nearly every incident is the lithium-ion battery—a powerful but volatile energy source.
When damaged, poorly manufactured, or improperly charged, these batteries can enter a state known as thermal runaway, causing:
- Rapid overheating
- Explosive ignition
- Intense, fast-spreading flames
Experts warn these fires behave differently from traditional fires, often producing toxic gases and explosive bursts.
2. Cheap and Unregulated Products
A major driver behind the surge is the influx of low-cost, unregulated devices sold through online marketplaces.
Fire safety experts consistently point to:
- Poor manufacturing standards
- Lack of safety certification
- Counterfeit batteries and chargers
Many incidents involve “cut-price products” with lax quality control, making them significantly more dangerous.
3. DIY Conversions and Black Market Batteries
Another growing concern is the rise of homemade or modified e-bikes, particularly among delivery riders.
Some users:
- Convert standard bikes using cheap kits
- Build batteries using recycled vape cells
- Use mismatched chargers
This underground market has created a high-risk ecosystem of unsafe modifications, significantly increasing fire hazards.
4. Improper Charging Habits
Charging practices also play a crucial role.Common dangerous behaviours include:
- Overnight charging while sleeping
- Using incorrect or incompatible chargers
- Charging near flammable materials
- Leaving devices unattended
These habits dramatically raise the likelihood of battery failure and fire.
London: The Epicentre of the Crisis
While the issue is nationwide, London stands out as the hardest-hit region.
The London Fire Brigade has identified borough hotspots such as:
- Lewisham
- Southwark
- Tower Hamlets
- Lambeth
- Westminster
Several factors contribute to London’s high numbers:
- Dense population
- High reliance on delivery services
- Greater adoption of e-mobility
- Smaller living spaces increasing fire risk
The brigade has repeatedly warned that many victims are not even the owners of the devices, highlighting the wider danger to households and neighbours.
