UK Regulations for E-Bikes

UK Ebikes Regulations

Share This Post

Like any mode of transportation, there are rules and regulations that govern their use in the UK. In this article, we will provide an overview of the current laws and regulations related to e-bikes in the UK, including speed limits, age restrictions, and requirements for helmets and lights. 

What is an e-bike? 

An e-bike, or electric bicycle, is a bicycle that is equipped with a battery-powered electric motor that assists with pedaling. The motor is activated by pedaling and can provide a boost to the rider, making it easier to climb hills or ride longer distances. E-bikes are classified as either pedal-assist or throttle-assist, depending on how the motor is activated. Pedal-assist e-bikes require the rider to pedal in order for the motor to engage, while throttle-assist e-bikes can be operated using a twist or thumb throttle. 

Speed limits for e-bikes 

In the UK, e-bikes are subject to speed limits that are determined by their classification. Pedal-assist e-bikes, which are the most common type of e-bike, are classified as ‘electrically assisted pedal cycles’ (EAPCs) and are subject to a maximum speed limit of 25 km/h (15.5 mph). Throttle-assist e-bikes, on the other hand, are classified as ‘powered transporters’ and are subject to a maximum speed limit of 25 km/h (15.5 mph) if used on the road, but can go up to 20 km/h (12.4 mph) if used on a cycle path. 

It is important to note that exceeding the speed limit on an e-bike is illegal and can result in a fine or penalty points on your driving license if you are caught. 

Age Restrictions for E-Bikes in the UK 

Another important regulation surrounding e-bikes in the UK is the age restriction. In the UK, there is no minimum age requirement for riding an e-bike, but there are different rules depending on the age of the rider and the power output of the bike. 

For riders under the age of 14, they are only allowed to ride e-bikes with a power output of 250 watts or less. Riders between the ages of 14 and 17 can ride e-bikes with a power output of up to 500 watts. For riders over the age of 18, there are no restrictions on the power output of the e-bike. 

UK E-bikes Classifications

The UK government has set out rules and regulations for e-bikes, which are classified into two categories: electrically assisted pedal cycles (EAPCs) and electric motorcycles. 

EAPCs are the most common type of e-bike and are subject to specific rules. Firstly, the motor’s maximum power output must not exceed 250 watts, and the bike’s maximum speed must not exceed 15.5 mph. Additionally, the rider must be pedalling for the motor to provide assistance. EAPCs are exempt from vehicle excise duty and are not subject to the same insurance and licensing requirements as electric motorcycles. 

EAPCs are also exempt from certain road rules that apply to motor vehicles, such as being able to use cycle paths, bus lanes and other designated cycling infrastructure. However, riders must still obey traffic laws and wear a helmet while cycling. 

E-bikes that do not meet the criteria for EAPCs are classified as electric motorcycles. These bikes must comply with different regulations, including licensing and insurance requirements, and riders must hold a valid driving license. Electric motorcycles also have different speed and power limits than EAPCs, with a maximum power output of 11 kW and a top speed of 28 mph. 

General Road Rules

It is important to note that any e-bike that does not meet the criteria for either EAPCs or electric motorcycles is not legal for road use in the UK. If you are unsure about your e-bike’s classification, it is best to consult with a professional or the manufacturer to ensure it complies with UK regulations. In addition to the specific regulations for e-bikes, there are also general road rules that apply to all cyclists in the UK. These include: 

  • Cycling on the left-hand side of the road, unless in a one-way street. 
  • Giving way to pedestrians on a shared path or crossing. 
  • Using hand signals to indicate turning or stopping. 
  • Using lights and reflectors when cycling in the dark. 
  • Wearing a helmet is not legally required, but it is strongly recommended. 

In the UK, e-bikes are classified as either pedal-assisted or throttle-assisted. Pedal-assisted e-bikes require the rider to pedal in order to activate the motor, while throttle-assisted e-bikes can be propelled solely by the motor without pedaling. The classification of the e-bike will determine the legal requirements for helmets and lights. 

Helmets and Lights


Although not legally required, it is highly recommended that pedal-assisted e-bike riders in the UK wear a helmet certified to safety standards like EN 1078. Conversely, riders of throttle-assisted e-bikes are required by law to wear a helmet meeting the same standards due to their increased risk of injury at higher speeds. All cyclists in the UK, including e-bike riders, must wear a well-fitted helmet that covers the forehead and back of the head and has adjustable straps under the chin. The helmet should also have a CE mark, indicating it complies with EU safety standards and be in good condition without any damage. 


In addition to helmets, e-bikes in the UK are also required to have lights. The law requires that an e-bike must have a white light at the front and a red light at the back. These lights must be visible from a distance of at least 100 meters and should be switched on during low light conditions or at night. 

It is important to note that e-bikes must also have reflectors on the pedals, the front wheel, and the back wheel. These reflectors help improve visibility and make it easier for other road users to see the e-bike, especially in low light conditions. 


In conclusion, e-bikes in the UK must comply with the same safety requirements as regular bicycles. This means that e-bike riders must wear a helmet that meets the EU safety standards, and the e-bike must have lights and reflectors to improve visibility. These requirements are essential for the safety of e-bike riders, and failure to comply with them can result in fines and penalties. 

As e-bikes continue to gain popularity in the UK, it is important for riders to prioritize safety and ensure that they comply with all safety regulations. By wearing a helmet and ensuring that the e-bike has the necessary lights and reflectors, riders can reduce the risk of accidents and enjoy a safer, more enjoyable riding experience.
