UL 2849. It tests the battery, the charger and the controller together under overcharge, short circuit, crush, thermal runaway, water ingress and vibration, and the system has to survive all of it without fire. It is now required by law in New York and California. UL 2271 covers the pack alone and IEC 62133 covers the cells alone, so neither tells you how the system behaves.

No. A certification covers the model as sold with the charger supplied. Fitting a replacement battery or a different charger voids it, and mismatched chargers are a leading cause of fire.

That depends on whether the maker still exists. When Faraday Bikes failed in 2019 its owners had no way to replace a worn pack and the bike became an expensive brick. Ask for the replacement part number and its price before you buy. Certification is also no guarantee of support: more than 20,000 budget e-bikes were recalled over battery fires and one maker declined full replacements for every owner, citing financial constraints.

No, and no maker says so. Official range is measured at 23C with unrealistically gentle acceleration. Which? found a 16 percent average shortfall across UK market models, and in cold weather What Car? found no car came within 20 percent of its official figure, some short by nearly 40 percent. In mixed UK driving expect 70 to 80 percent of the brochure number.

No. The branded trims sold as vegan leather, Veganza, Sensatec, MB-Tex, Artico and SofTex among them, are polyurethane or PVC. PVC is softened with phthalates, which are endocrine disruptors, it does not biodegrade, and it sheds microplastics as it wears. Removing the animal is a real gain on welfare. It is not automatically a gain on materials.

No. Non exhaust sources are now around 60 percent of roadside PM2.5 and 73 percent of PM10, and tyre wear alone runs over a thousand times the regulated exhaust limit. Battery electric vehicles cut brake dust by roughly 83 percent through regenerative braking but add tyre wear through weight, netting about 38 percent less total particulate than petrol. No maker publishes a tyre wear figure, and Euro 7 is the first rule to touch it.
