As electric bikes continue to surge in popularity across the UK, understanding the laws that govern them has become more important than ever—especially if you own or are considering a foldable electric bike. Whether you're using your foldable electric bike for commuting, road-tripping, or simply exploring your local countryside, adhering to the law guarantees your safety and comfort.
In 2025, several updates have been introduced to UK legislation concerning e-bikes, reflecting the rapid growth in demand and the government’s push toward sustainable transport solutions. This guide breaks down everything you need to know about UK law and foldable electric bikes in 2025—from classification and age requirements to insurance and riding restrictions.
What Is a Foldable Electric Bike?
Before diving into the legal side, let’s clarify what we mean by a foldable electric bike, or e-bike. These bikes are electrically assisted bicycles with compact, collapsable frames that make them ideal for commuting, travel, and storage. They combine the portability of a traditional fold-up bike with the convenience of an electric motor, offering pedal assist or throttle-based acceleration.
Legal Definition: Is a Foldable Electric Bike a "Bicycle"?
According to UK law in 2025, an electric bike is classified as an EAPC—Electrically Assisted Pedal Cycle—if it meets the following criteria:
-
Has pedals that can be used to propel it
-
The electric motor provides assistance only when pedalling
-
The motor cuts out at 15.5 mph (25 km/h)
-
The motor power output does not exceed 250 watts
-
The bike must display the manufacturer’s details and the power output or maximum speed on a visible label
If your foldable electric bike meets all five conditions, it is legally considered a bicycle, meaning you do not need a license, insurance, or registration to ride it on UK roads.
Age Restrictions in 2025
To ride an EAPC in the UK, you must be at least 14 years old. This hasn’t changed in 2025. However, stricter enforcement has been noted, particularly in urban areas where foldable e-bikes are commonly used for short-distance commutes.
Insurance & Registration: Do You Need Them?
If your e-bike falls within the EAPC classification, insurance and vehicle registration are not required. However, if your foldable electric bike exceeds 250 watts or can be propelled without pedalling (i.e., it has a throttle-only function), it is considered a motor vehicle. In this case, you will need:
-
A driver's license
-
Insurance
-
Vehicle registration
-
A number plate
-
A helmet (compulsory)
Most popular foldable e-bikes, like those from eelo, comply with EAPC regulations, making them road-legal without added bureaucracy.
Where Can You Ride a Foldable Electric Bike?
In 2025, foldable electric bikes classified as EAPCs are allowed on:
-
Public roads
-
Cycle lanes
-
Bridleways
-
Shared-use paths
You cannot ride them on pavements (sidewalks), unless it is a designated cycle path. The Highway Code remains strict with this rule to ensure pedestrian safety.
For e-bikes exceeding EAPC limits, the rules are much tighter. They are treated like mopeds and must not be used on cycle paths or bridleways.
Helmet Laws: Are Helmets Required?
As of 2025, wearing a helmet while riding an EAPC is not legally required but is strongly recommended, particularly in high-traffic areas. The Department for Transport has launched awareness campaigns urging cyclists—including e-bike users—to wear helmets to reduce head injuries, even for low-speed travel.
Battery Safety & Regulations
Battery technology has advanced significantly recently, and in 2025, the UK introduced new safety standards for lithium-ion batteries used in electric bikes:
-
All e-bike batteries sold in the UK must meet BS EN 50604-1 standards.
-
Batteries must now include built-in thermal cutoffs to prevent overheating.
-
Riders are advised to use only manufacturer-approved chargers and avoid aftermarket charging accessories.
Improperly maintained or poorly made batteries have been linked to fire risks, leading to tighter regulations. Always check if your foldable e-bike complies with these standards—especially if you purchase from lesser-known brands or import one from abroad.
Folding & Carrying on Public Transport
Foldable electric bikes enjoy added flexibility on UK public transport. In 2025:
-
Trains: Most train services allow foldable e-bikes onboard, provided they are fully folded and do not exceed size limits (typically 85 cm x 70 cm x 35 cm).
-
Tube (London Underground): Foldable e-bikes are allowed outside peak hours. Batteries must be switched off during transport.
-
Buses: At the driver's discretion. Smaller foldables are more likely to be accepted, especially outside rush hour.
Be sure to check individual transport providers' policies before travelling.
Recent Updates in 2025: What’s New?
Here’s what’s newly introduced in 2025 regarding electric bike law:
-
Digital e-bike registration platform: While registration is still not mandatory for EAPCs, a new voluntary registry has been launched to help trace stolen bikes.
-
Subsidies for compliant e-bikes: The UK government has expanded its Clean Travel initiative to include discounts for foldable e-bikes that meet energy efficiency standards.
-
Urban low-speed zones: In several cities like London, Manchester, and Bristol, dedicated e-bike priority lanes have been introduced in low-emission zones to encourage micromobility.
