The festive season took a devastating turn for a London family when a second-hand e-bike battery exploded, engulfing their Catford home in flames just days before Christmas. The incident, which occurred on December 14, 2024, serves as a stark reminder of the growing fire risks associated with e-bikes and the importance of safe charging practices.
A Terrifying Night in Catford: E-Bike Battery Ignites Inferno
On a Saturday night that should have been filled with holiday cheer, a terrifying scene unfolded in Renshaw Close, Catford. A seemingly innocuous charging e-bike battery erupted in flames, rapidly spreading fire throughout the family home. The London Fire Brigade (LFB) reported receiving 23 calls about the blaze, describing the scene as chaotic with “several bangs and small explosions” as the fire intensified. Chilling doorbell camera footage captured by a neighbor and shared by the LFB on Facebook vividly depicts the escalating inferno, with flames erupting from the second floor and accompanied by a series of loud pops. The footage then shows the arrival of first responders battling the raging fire engulfing the second story.

Escape from the Flames: Residents Trapped by Raging Fire
Three people were inside the house when the e-bike battery exploded on the first floor. While one occupant managed to escape unharmed through the front door, the other two found their exit blocked by the rapidly spreading fire. In a desperate attempt to escape, they climbed onto the roof through a skylight window. Tragically, one of the occupants, a man, fell from the roof and was discovered by firefighters in the garden upon their arrival. He sustained serious injuries, though thankfully, they are not considered life-threatening. The other occupant, a woman, remained trapped on the roof until firefighters were able to rescue her. She was treated for smoke inhalation. The fire caused extensive damage, destroying most of the first floor and the loft conversion.
A Growing Concern: E-Bike Fires on the Rise in London
This incident underscores a significant and growing concern in London: the increasing number of fires caused by e-bikes and e-scooters. According to Deputy Assistant Commissioner Richard Field of the LFB, there have been approximately 160 such fires in London in 2024 alone, averaging almost one every other day. He described the December 14th fire as “a devastating fire that has destroyed most of a family home,” emphasizing the fortunate outcome that no lives were lost given the speed and intensity of the blaze.
The Dangers of Modified E-Bikes and Improper Charging
Field revealed that the e-bike involved in the fire was a converted pedal cycle fitted with a lithium-ion battery pack purchased from an online marketplace. Crucially, the battery was being charged with a generic charger not specifically designed for it. This highlights a critical issue: the dangers of modifying e-bikes with second-hand or incompatible components and using incorrect chargers. According to Field, “some of these vehicles are proving to be incredibly dangerous and are at greater risk of malfunctioning, particularly if they’ve been modified, fitted or converted with second-hand products or if the batteries are used with the incorrect chargers.” Lithium-ion batteries, while efficient, pose a significant fire risk if damaged, overcharged, or charged with incompatible equipment. The chemical reactions within the battery can generate intense heat, leading to thermal runaway and potentially catastrophic explosions.

E-Bike Safety: Essential Tips to Prevent Fires
The LFB has issued crucial safety advice for e-bike and e-scooter owners to mitigate the risk of fires:
- Purchase from Reputable Sellers: Buy e-bikes and chargers from reputable retailers to ensure quality and compatibility. Avoid second-hand batteries and chargers unless they are certified by the original manufacturer.
- Charge Outdoors: Whenever possible, charge e-bikes and e-scooters outdoors or in a well-ventilated area like a shed or garage. This minimizes the risk of fire spreading to the home.
- Indoor Charging Precautions: If charging indoors is unavoidable, never charge on an escape route. Choose a room with a closing door and working smoke alarms.
- Use the Correct Charger: Always use the charger specifically designed for your e-bike battery. Using an incompatible charger can damage the battery and significantly increase the risk of fire.
- Never Overcharge: Follow the manufacturer’s instructions for charging times. Overcharging can lead to overheating and fire.
- Supervise Charging: Never leave e-bikes or e-scooters charging unattended, especially overnight or when you are away from home.
Frequently Asked Questions about E-Bike Fire Safety
Q: What should I do if my e-bike battery catches fire?
A: Call emergency services immediately. Do not attempt to extinguish the fire yourself. Evacuate the area and warn others.
Q: Are all e-bike batteries equally dangerous?
A: The risk of fire is higher with damaged, modified, or poorly manufactured batteries. Using the correct charger and following safety guidelines significantly reduces the risk.
Q: How can I tell if my e-bike battery is damaged?
A: Look for signs of physical damage, such as cracks, dents, or swelling. If the battery overheats excessively during charging or emits unusual odors, it could be damaged.
This tragic incident serves as a crucial reminder of the importance of e-bike safety. By following these guidelines, e-bike owners can significantly reduce the risk of fire and protect themselves and their families.
