EAPC Regulations for Electrically Assisted Pedal Cycles (EAPC)

The EAPC guidelines set out clear technical and operational standards for e-bikes. Below is an in-depth explanation of the requirements:

1. Bike Construction and Propulsion

Mandatory Pedals:
The bike must be equipped with pedals that allow the rider to manually propel the vehicle. This ensures that the electric motor supplements, rather than replaces, human power.

2. Speed Restrictions for Motor Assistance

Motor Cut-off Speed:
The electric motor is designed to disengage once the bike reaches a speed of 15.5 mph (25 km/h). This means that while the motor aids propulsion at lower speeds, it will not actively drive the bike once this speed threshold is surpassed.

3. Power Output Limitations

Motor Power Cap:
The maximum power output of the motor is strictly limited to 250 watts. This restriction helps maintain safety standards and ensures that the bike is classified correctly under the EAPC rules.

4. Information Display Requirements

Approved e-bikes under the EAPC guidelines must feature a display or device that provides key information:

Motor Details:
The display should indicate either the power output of the motor or clearly show the manufacturer's name.

Battery or Speed Data:
It must also present either the battery voltage or the maximum achievable speed of the bike.

These regulations help ensure that e-bikes are used safely and are easily identifiable in terms of their performance characteristics.
