E-bikes under the spotlight: Surge in fires blamed on mods and uncertified parts

18 June 2026

While the picture for electric cars appears relatively reassuring, the situation is quite different for e-bikes. In 2025, electric bicycles were involved in approximately 520 fires in the United Kingdom, a figure representing nearly a third of all incidents recorded throughout the year. Compared to 2022, the increase reached 249%, a growth rate significantly higher than that observed in the automotive sector.

Experts have highlighted a particularly significant factor. Many of the e-bikes involved in the fires had been modified or equipped with substandard batteries and components that fell short of required standards.

In several cases, uncertified batteries, incompatible chargers, or altered electrical systems were used to boost performance and speed. For this very reason, industry experts emphasize the importance of purchasing certified products and using only original or manufacturer-approved batteries. The charging process also plays a critical role: avoiding non-compliant chargers and never leaving batteries charging unattended can significantly reduce the risk of accidents.

The vast majority of global battery production is concentrated in China. In this context, ECM operates with a unique strategic advantage thanks to our branch, Ente Cerma Certification Shanghai. Having a direct presence on the ground in China allows us to monitor production processes in real time and verify that partners comply with both local standards (GB/T) and rigorous international protocols (UN 38.3, UL, IEC), as well as the new EU Regulation.

Turning geographical distance into a strength is essential. Ensuring pre-compliance before products leave Asia guarantees that imported batteries are safe and sustainable. In a market that allows no compromises, certification becomes the ultimate shield to protect consumers and ensure the solidity of the tech business.
