The charity Electrical Safety First (ESF) has expressed concerns over “incomplete” e-bike kits, stating that consumers are often left to pair batteries and chargers themselves, which can lead to compatibility issues and increase fire risks, according to the BBC.

Product safety engineer Giuseppe Capanna noted that some kits bought online may lack essential components, such as the battery and charger, which places the responsibility on the consumer to find suitable replacements—often resulting in mistakes.

“You have a high risk that a charger won’t be compatible with the battery. The battery could then become overcharged – that’s one of the things that can cause it to go into thermal runaway, which causes it to catch fire and explode” Capanna explained.

Capanna, however, emphasized that reliable companies do sell safe kits, and suggested referring to guides, for reputable options.

In its Battery Breakdown report released last year, ESF pointed out that well-designed conversion kits from reputable manufacturers, when installed professionally, are generally safe. Nonetheless, the charity advocates for stricter safety standards for these kits, highlighting that many kits available online do not include a battery, leaving it up to consumers to find and ensure compatibility with a charger.

ESF also raised concerns over some kits offered by less reputable sellers, which exceed legal power limits, putting both riders and pedestrians at risk and potentially subjecting users to legal consequences.

In response, the National Fire Chiefs Council (NFCC) has called for stronger product safety regulations for e-bike kits and stricter sales oversight. The NFCC supports ESF’s recommendation for third-party certification of e-bikes, e-scooters, and batteries, noting that current regulations allow manufacturers to self-declare battery safety.

The upcoming Product Regulation and Metrology Bill, recently introduced in the King’s Speech, aims to address unsafe products sold by overseas suppliers in the UK. A Department for Business and Trade spokesperson stated, “We take the risk of e-scooter and e-bike fires very seriously. That’s why we’re working with local authorities to identify illegal products to prevent them from being imported, while notifying consumers and businesses about unsafe products.

“The Product Regulation and Metrology Bill will allow us to amend product regulations, respond swiftly to innovative new products and maintain high safety standards.“
