• E-Bikes: In the UK, riders must be at least 14 years old to ride an electric bike (with a maximum motor power of 250 watts). Riders under 14 should not be using E-bikes on public roads or in public spaces.
• Electric Motorcycles: These vehicles are considered motorbikes, so riders need to be at least 17 years old to ride an electric motorcycle on public roads, and they must hold the appropriate licence (either a provisional or full motorcycle licence).

• E-Bikes: The motor should not exceed 250 watts, and the bike should not assist the rider beyond 15.5 mph (25 km/h) on level ground. If these limits are exceeded, the bike is considered a motor vehicle, requiring full licensing, insurance, and registration.
• Electric Motorcycles: Riders of electric motorcycles must comply with full legal requirements for motor vehicles, including insurance, tax, and a valid licence plate.

• E-Bikes: These can be used on cycle paths, roads, and some bridleways but not on pavements unless specifically allowed.
• Electric Motorcycles: These must be ridden on public roads and should follow the same rules as petrol-powered motorcycles. Riders must wear appropriate safety gear, including a helmet.
