What Is
an EAPC?

What EAPC stands for

EAPC is short for Electrically Assisted Pedal Cycle. It is the legal term the UK uses for an electric bike that meets a specific set of technical limits. When a bike meets those limits, the law treats it identically to a conventional push-bike — that single fact is why an EAPC needs no licence, no road tax, no registration and no compulsory insurance.

Think of "EAPC" not as a type of bike you buy, but as a legal status a bike either has or doesn't have — the same way a driver "has a clean licence".

The three rules that define an EAPC

A bike only counts as an EAPC if it ticks every one of these boxes:

1. It has usable pedals

The bike must have pedals that are capable of propelling it. A machine with no working pedals can never be an EAPC, no matter how it is marketed.

2. The motor is 250W or less

The motor's continuous rated power must not exceed 250 watts. This is the sustained output the motor is designed to deliver, not a short peak figure. Learn more in our guide to e-bike speed and power limits.

3. Assistance cuts off at 15.5 mph

The motor must stop providing power once the bike reaches 15.5 mph (25 km/h). You are free to pedal faster under your own effort — but the motor cannot push you past that limit.

Things that surprise people about EAPCs

  • EAPCs can have more than two wheels. Electric tricycles and some cargo trikes can qualify too, as long as they meet the rules.
  • Looking like a moped doesn't make it one. A bike like the Eskuta SX-250 is styled like a motorcycle but is built to EAPC limits, so legally it's a bicycle.
  • Throttles are restricted, not banned. Post-2016 bikes can use a throttle only up to 6 km/h without pedalling. See e-bike throttle laws.
  • Markings matter. EAPCs should display the manufacturer's name, the motor's power output and either the battery voltage or the motor's maximum speed.

What happens if a bike isn't an EAPC?

If a bike breaks any of the three rules — too powerful, too fast under motor power, or no usable pedals — it is no longer legally a bicycle. It becomes a moped or motorcycle, which must be registered, taxed, insured, type-approved and ridden by a licensed rider in a helmet. We cover this fully in e-bike vs moped vs motorcycle.

How do I know if my bike is an EAPC?

The quickest way is to run through our EAPC compliance checklist. Check the motor's rated wattage, confirm the assistance cuts out at 15.5 mph, make sure the pedals work, and look for the required markings. The Eskuta SX-250 meets EAPC requirements out of the box.

Common questions

Frequently asked questions.

  • Electrically Assisted Pedal Cycle — the UK legal category for road-legal electric bikes that are treated as ordinary bicycles.

  • An EAPC is an e-bike that meets the legal limits (250W, 15.5 mph cut-off, working pedals). All EAPCs are e-bikes, but not every e-bike qualifies as an EAPC.

  • Yes. EAPCs can have two or more wheels, so electric tricycles and some cargo trikes can qualify as EAPCs.
