If you’ve spent any time in a British city centre lately, you’ve probably seen it: a courier pulled over, a police officer crouched by the rear wheel, and a very expensive bike about to be loaded onto a van.
It’s happening a lot. And as of summer 2026, it’s about to happen faster.
The 250W line that decides everything
UK law splits electric bikes into two groups, and the gap between them is enormous.
On one side sits the EAPC — an Electrically Assisted Pedal Cycle. GOV.UK sets out the test: pedals that actually propel the bike, a motor with a continuous rated power output of no more than 250 watts, and assistance that stops at 15.5mph. Tick those boxes and your bike is legally a bicycle. No licence, no tax, no insurance, no helmet law, and you can use cycle lanes.
Miss any one of them and your bike is legally a motorcycle or moped. Now you need registration, vehicle tax, a valid driving licence, insurance and a motorcycle helmet that meets British safety standards. You also lose cycle lanes entirely — non-EAPCs can only be ridden on the road.
Most riders don’t cross that line by accident. They cross it because a faster bike means more drops per hour.
Why couriers specifically
The maths is brutal. Gig work pays per delivery, so 20mph instead of 15.5mph is real money. Conversion kits and derestriction tools are cheap, easy to fit and sold openly online.
The problem is that the moment a bike does more than 250W or assists past 15.5mph, the rider is — in the eyes of the law — riding an unregistered, untaxed, uninsured motorbike. GOV.UK is blunt about the consequence: you may get a fine, or your bike may be seized by police.
Enforcement is real, not theoretical. During a Lords debate in June 2025, Hansard records that the City of London Police — the smallest force in the country — seized 325 e-cycles in 2024 alone.
The rule change that removes your second chance
Until recently, police often had to issue a warning before seizing a vehicle used anti-socially. That step is gone.
Section 8 of the Crime and Policing Act 2026 repeals subsections 59(4) and (5) of the Police Reform Act 2002, removing the requirement for an officer to give a warning first. The Act received Royal Assent on 29 April 2026, and that section came into force on 29 June 2026.
Translation: no warning, no second chance, no ride home.
How to stay on the right side of it
- Check the markings. An EAPC must show its continuous rated power output and the manufacturer, plus either battery voltage or the motor’s maximum speed.
- Be suspicious of “750W”, “1000W” or “unlocked to 20mph+” in a product listing. Those are motorcycle specs.
- If a bike has a throttle that drives it to 15.5mph without pedalling, it needs vehicle approval — and most grey imports don’t have it.
A legal e-bike is slower. It’s also still yours at the end of the shift.
