Regulations

E-bikes and the law in Spain (2026)

Helmet, insurance, licence, pavements and bike lanes: which rules apply to a pedal-assist e-bike and what changed in October 2026.

Updated on 9 November 2026 · Data from 17 models analysed

In legal terms, a pedal-assist e-bike counts as a bicycle: it needs no driving licence, number plate, roadworthiness test or compulsory insurance. Since 1 October 2026, however, helmets are compulsory for all cyclists on interurban roads.

What counts as a legal e-bike

To be considered a pedal-assist bicycle it must meet three conditions:

  • A motor with a rated power of 250 W at most.
  • It only helps while you pedal: no throttle that moves it on its own (walk assist for setting off is allowed, up to 6 km/h).
  • Assistance cuts out at 25 km/h.

The Decathlon e-bikes we analyse on Cadencia are of this type.

Helmets: what changed in October 2026

Royal Decree 518/2026 amended Spain's General Traffic Regulations and came into force on 1 October 2026:

  • Roads and interurban routes: helmets are compulsory for all cyclists. The previous exceptions no longer apply.
  • Under-16s: helmets are compulsory on all roads, including in town.
  • Adults in town: not compulsory, but strongly recommended.

Insurance

Law 5/2025 requires insurance for light personal vehicles such as e-scooters, but excludes pedal-assist bikes that meet the limits above. Even so, voluntary third-party liability insurance is a good idea: it is sometimes already included in home insurance or a cycling federation licence.

Traffic rules that also apply to you

  • Alcohol: cyclists have the same limits as drivers.
  • Phone and headphones: holding your phone and wearing headphones while riding are both prohibited.
  • Lights: at night and in tunnels, a white front light, a red rear light and a rear reflector. On interurban roads, a reflective garment as well.
  • Pavements: as a general rule you cannot ride on the pavement unless signposted.
  • Bike lanes and streets: each town hall has its own bylaw. Check the one for your city.

What is not an e-bike

Bikes that assist up to 45 km/h (speed pedelecs) or have a throttle count as mopeds: they need an AM licence, number plate, insurance and an approved helmet, and cannot use bike lanes.
