In the Netherlands, an electric bike is legally an ordinary bicycle only when it passes every one of four tests: the motor is 250 W or less, the assist ends above 25 km/h (about 15.5 mph), the assist also ends when you stop pedaling, and you have to pedal to go forward. A walk assist that helps up to 6 km/h (about 3.7 mph) is allowed on top of that. Miss any test and the law treats the vehicle as a snorfiets (a Dutch light-moped class), a bromfiets (moped) or a motorfiets (motorcycle), which means a registration plate (kenteken) and moped-style rules.
That is how RDW, the Dutch vehicle authority, and the Rijksoverheid government site describe it. Both pages are in Dutch; this guide reflects them as published in October 2026. Other countries differ, and E-Bike Laws: What You Can and Cannot Do (US, UK and EU) compares several.
The four tests
RDW lists the characteristics of an electric bicycle, and a bike that misses any of them does not qualify. They come down to four tests.
- Motor power of 250 W or less. A watt measures power, here how hard the motor can work. Because the tests stack, a controller that cuts the assist at 25 km/h does not rescue a motor above 250 W. That bike fails on power alone.
- Assist that ends above 25 km/h. Past that speed the motor must stop helping.
- Assist that ends when you stop pedaling. The motor has to respond to your legs: no pedaling, no help. That is what pedal assist means.
- Pedaling required to move forward. A throttle, which drives the motor from a hand or thumb control without any pedaling, is a different system. The explainer on e-bike throttle vs pedal assist covers the practical difference.
Walk assist is an allowance, not a fifth test
RDW says an electric bicycle may have a walk assist, a mode that helps push the bike while you walk beside it. If the bike has one, it may help only up to 6 km/h. A bike without one is not penalized, and a bike with one still has to meet all four tests above.
Where the two official pages differ
- The 6 km/h figure. RDW describes it as help while you walk alongside the bike. Rijksoverheid names a throttle that moves you faster than 6 km/h without pedaling as a feature that takes a fatbike out of the e-bike category. A slow throttle used while riding is left open, so treat the allowance as a walking aid and ask the seller to confirm in writing that the model meets the e-bike criteria.
- Plate versus inspection. RDW says a bike that fails the tests must have a plate. Rijksoverheid says it must be inspected as, for example, a bromfiets, snorfiets or speed pedelec. Either way, it cannot be treated as a bicycle.
- Which moped-type rules. RDW groups snorfiets, bromfiets and motorfiets together and lists a plate, helmet, driver’s license and insurance. Rijksoverheid adds that the rules for a bromfiets differ from those for a snorfiets, so check the exact category.
E-bike versus speed pedelec
Rijksoverheid names the main dividing line directly: a speed pedelec, the fast kind of e-bike, is legally a moped. The table shows what changes with that status.
| Feature | Electric bicycle | Speed pedelec |
|---|---|---|
| Pedal assist up to | 25 km/h | 45 km/h (about 28 mph) |
| Motor power | 250 W or less | 4,000 W or less |
| Legal class | Bicycle: same traffic rules as an ordinary bike | Bromfiets (moped), category L1e-B |
| Registration plate | Not required | Yellow plate |
| License and age | No driver’s license, no minimum age | Moped license, rider must be 16 |
| Helmet | Not required, but advised | Mandatory |
| WA (third-party liability) insurance | Not required | Mandatory |
Fatbikes and cargo e-bikes
A fatbike is an e-bike with extra-wide tires. Rijksoverheid states that fatbikes and electric cargo bikes (bakfietsen) count as electric bicycles too, but only when they pass the same tests. None of the tests mention tire width, frame style or cargo capacity. In practice that gives three outcomes:
- Passes every test: the electric-bicycle rules apply.
- Fails any test, for example a motor above 250 W, a throttle that drives it faster than 6 km/h without pedaling, or assist beyond 25 km/h: RDW says it needs a plate like a speed pedelec, bromfiets or motorcycle, and Rijksoverheid says it must be inspected as, for example, a bromfiets, snorfiets or speed pedelec. The moped-style rules of that category then apply to the rider.
- Fails any test and has neither a plate nor type approval: RDW says the vehicle is prohibited on the road. A fatbike that passes every test needs no plate, so this ban does not reach it.
If a manufacturer has type approval for the vehicle, the proof is a Certificate of Conformity (Certificaat van Overeenstemming), and with it you can apply to RDW for a plate.
Before buying a fatbike or cargo e-bike, run through this list:
- Ask for the motor’s continuous rated power and compare that with the 250 W limit.
- Confirm that the assist stops at 25 km/h and when you stop pedaling.
- Find out whether any throttle or walk-assist button can move the bike faster than 6 km/h without pedaling.
- For a machine sold as moped-class, ask for the type-approval proof.
A listing may quote a peak figure instead of the continuous rating. EU Regulation 168/2013 describes pedal-assist cycles by a maximum continuous rated power of 250 W or less, defined as the maximum thirty-minute power at the output shaft of an electric engine. The Dutch pages say only “maximaal 250 watt”, so ask the seller which figure a listed wattage is.

What a non-compliant or altered bike costs
A bike’s limits define its legal category, so changing them is not a tweak. According to Rijksoverheid, a bike stops being an e-bike once its speed limiter is altered or removed, or once it has a throttle giving motor support above 6 km/h, and it then counts as a speed pedelec, moped or snorfiets. RDW adds that if a speed change moves a vehicle into another category, it must be inspected. Skipping that step has concrete consequences:
- No insurance cover. On a non-compliant fatbike you are not insured. After an accident you pay for damage to the bike and for medical costs yourself, and damage you cause to someone else can land on you as well.
- Fines and seizure. A bike with a throttle or a modification that is not registered as a speed pedelec, moped or snorfiets can draw a fine of €320. After repeated offenses the police may seize and destroy it.
If you are unsure whether your own bike qualifies, ask RDW or the seller before riding it on public roads.
A pending helmet rule for young riders
A compliant electric bicycle needs no helmet, although Rijksoverheid advises wearing one. One change is pending: the cabinet plans a helmet requirement for riders under 18 on fatbikes and other e-bikes, which still needs approval from the Tweede Kamer and Eerste Kamer, the two houses of parliament. Check the Rijksoverheid page for the current status. For choosing a helmet, see Cycling Helmets: How They Work, MIPS, and Choosing the Right One.
