Electric Bicycle or Moped: How to Tell the Difference
Pedal assistance, the 250 W limit and cut-off at 25 km/h help identify an EPAC. Confirm the category of a specific vehicle in its official documentation.
Key points
An electrically assisted pedal cycle (EPAC) provides assistance only while pedalling, with a maximum continuous rated power of 250 W and progressive assistance cut-off at or before 25 km/h. If a vehicle does not meet these criteria, check the official documents for that specific version rather than assuming it is a bicycle.
The key difference: how the assistance works
An electrically assisted pedal cycle, or EPAC, must assist the rider while they pedal. Assistance stops when they stop pedalling and is also progressively cut off at or before 25 km/h. Its auxiliary motor has a maximum continuous rated power of 250 W.
If a vehicle does not meet these criteria, do not assume it is a bicycle based on its appearance, its sales name or the fact that it has pedals. It may belong to another category, such as a moped, but you must confirm its classification in the official documents for that specific vehicle and version.

What the 250 W limit and 25 km/h cut-off mean
The European reference for this exemption is maximum continuous rated power, not just any power figure shown in an advert or commercial description. The operating mode also matters: the motor must assist pedalling, stop assisting when the rider stops pedalling, and progressively reduce assistance until it cuts out at or before 25 km/h.
These details should therefore be considered together. A single speed, power or range figure is not enough to identify the vehicle category. Check the specifications declared by the manufacturer for the specific version and how it describes the assistance system.
| Criterion | Requirement |
|---|---|
| Motor power | Up to 250 W maximum continuous rated power |
| Assistance | Only while pedalling |
| Assistance cut-off | Progressive cut-off at or before 25 km/h; assistance also stops when the rider stops pedalling |

- Power: look for the declared maximum continuous rated power.
- Speed: confirm that assistance is progressively cut off at or before 25 km/h.
- Pedalling: check that assistance stops when the rider stops pedalling.
Appearance and adverts do not settle the classification
Pedal assistance and the power and speed limits described above can help identify an EPAC. To determine the category of a specific vehicle, consult its official documentation.
Appearance, fitted pedals and sales terms such as “electric bicycle” or “electric motorcycle” are not enough either. These labels do not replace the technical specifications or type-approval documents for the model.

What to check before buying in Spain
Ask for the official documents for the specific vehicle and version, then compare them with the advert. Confirm the vehicle category, maximum continuous rated power, the speed at which assistance cuts out, and whether it stops when the rider stops pedalling. If the information conflicts or the documents do not clearly identify the category, ask the seller or manufacturer for clarification before paying.
The classification matters because it determines which rules apply to the vehicle. The specific obligations for a vehicle cannot be determined without knowing its category and documentation. For guidance on procedures, see Rules and procedures and light mobility vehicles, as well as the official information that applies to the model.

- Ask for the type-approval documents and technical specifications, if applicable to that category.
- Check that the information applies to the same version being offered.
- Compare the documents with the operating details provided by the manufacturer; do not rely on the advert alone.
Can an electrically assisted pedal cycle travel faster than 25 km/h?
It can travel faster using the rider’s own momentum, but motor assistance must be progressively cut off at or before 25 km/h.
What determines whether an electric bicycle is an EPAC?
The criteria described are assistance while pedalling, maximum continuous rated power of 250 W, and progressive assistance cut-off at or before 25 km/h. Check the official documentation to confirm the category of a specific vehicle.
What should I check first in an advert?
Compare the maximum continuous rated power, assistance mode and 25 km/h cut-off with the official documents for that version. The advert alone does not establish the vehicle category.
