Is it illegal to ride an e-bike after a drink? UK e-bike laws you need to know

Did you get an electric bike for Christmas, or are you starting the new year with plans to get more active? As e-bike popularity grows, so does the complexity of understanding the rules surrounding their use. From illegal modifications to speed limits, online bike retailer Paul’s Cycles has rounded up the most important UK e-bike rules.

Adam Cross, the brand’s Customer Care Manager, shares: “In light of the growing popularity of e-bikes and the accompanying increase in misuse and misinformation, understanding and following road safety laws is crucial for their responsible use.

“It’s important to keep up to date on the risks associated with aftermarket batteries, chargers, and conversion kits, as well as the significance of adhering to road regulations. This knowledge helps riders make safer, more informed choices, ensuring e-bikes continue to be a convenient, healthy, and sustainable mode of transportation.”

1. Make sure your e-bike is road-legal

Generally, an e-bike must abide by the following rules to be road-legal within the UK:

  • The cycle must be fitted with pedals that are capable of propelling it.

  • The maximum continuous rated power of the electric motor must not exceed 250 Watts.

  • Electric bikes must be clearly marked with information about the vehicle including its manufacturer, maximum speed or nominal voltage capabilities and the maximum continuous rated power or output of the motor.

  • The electrical assistance must be cut off when the vehicle reaches 15.5 mph.

Make sure to get your e-bike from a respected retailer, as they will ensure the bikes sold meet UK regulations. Adam notes, “As members of The Electric Bike Alliance, we support efforts to address misinformation and promote the safe use of e-bikes in the UK. The Electric Bike Alliance brings together organisations, charities, and businesses to encourage the responsible use of e-bikes, batteries, and chargers. You can use their tool to find a local retailer that prioritises e-bike safety.”

2. Be wary of illegal modifications

Modifying your electric bike, or buying one that has already been tinkered with, could actually make it illegal to use. You cannot legally ride an e-bike with changes that mean the bicycle no longer complies with UK regulations. This could include exceeding the motor power and speed capabilities or adding a throttle to allow you to ride the bike without pedalling.

If you get caught with an e-bike that is not road legal, it may be classed as a motor vehicle without a licence and you could get hit with six penalty points and a £300 fine for driving without insurance. 

3. No cycling home from the pub

E-bike riders must still follow the rules and regulations set out for traditional bicycles and can be prosecuted under the 1988 Road Travel Act for dangerous, careless or inconsiderate cycling and cycling under the influence of alcohol or drugs.

The wanton or furious riding law has also been used to prosecute cyclists in extreme cases. This is defined as driving or cycling in a way that is reckless or dangerous, and causes, or could cause, bodily harm to others.

4. Other surprising rules

  • The only places in the UK that have a legal requirement to have a bell on your bike are Northern Ireland and the Isle of Man. This applies to all bikes, not just the electric kind!

  • Although not widely known, officially, e-bikes are not allowed inside any type of property managed by the Government Property Agency (GPA), according to a position statement released in June 2024.

  • Cyclists aren’t obligated to UK-wide speed limits and that includes electric bikes. While you are limited to motor-provided assistance of up to 15.5mph, you can pedal as fast as you like provided that the rider is the sole source of the power.
