US Class 1, Class 2 and Class 3 labels do not translate directly into ordinary European bicycle status. Compare the motor, assistance behaviour and actual destination rules. Shipping location and familiar model names do not establish the legal category.
Use this comparison within its scope
The US examples below follow California's official consumer guidance reviewed on 28 October 2026. They are not uniform rules for every US state. The European column describes the ordinary pedal assistance boundary used in the French and German sources, not every powered bicycle category.
| Category | Assistance behaviour | Important limit or distinction |
|---|---|---|
| California Class 1 | Pedalling assistance | Assistance ends at 20 mph |
| California Class 2 | Motor assistance can operate without pedalling | Assistance ends at 20 mph |
| California Class 3 | Pedalling assistance | Assistance ends at 28 mph; additional rider requirements apply |
| Ordinary pedal assistance in France and Germany | Assistance linked to pedalling under the applicable conditions | 250 W maximum continuous rating and assistance ending by 25 km/h |
| Vehicles outside these categories | Depends on actual controls, power and speed | Separate approval and use requirements can apply |
California's cited guidance also sets its motor boundary at 750 W for its electric bicycle categories and describes permanent class labels. Germany allows qualifying starting or walking assistance up to 6 km/h. These details show why the presence of any motor control cannot be assessed using only one headline speed.
Keep product safety and road access separate
Product safety evidence addresses the supplied product and its risks. Road classification determines how it is treated under transport law. Local access rules determine where that category can be used. Safety marks do not automatically grant access to every cycle path, while an access rule does not prove the product has all required safety documentation.
California also has additional Class 3 age and helmet requirements. Local authorities can restrict routes. For another state or country, start with its own current authorities rather than carrying those assumptions across the border.
For journeys or purchases from January 2027, review California's updated rules again. Sacramento's official guidance flags legislation signed in September 2026 with changes taking effect on 1 January 2027. Do not treat future requirements as already effective on this guide's review date.
What this means for the ARSK models
The current supplied F6 Pro is 500 W. It does not fit the ordinary 250 W French or German pedal assistance boundary. That fact does not automatically establish any particular US class, European motor vehicle category or registration eligibility.
XT90's stated 250 W continuous rating and 25 km/h cutoff are relevant starting facts, but its actual supplied controls and documents still need to match. Confirm X5's motor power and controls before assigning its legal category.
Before purchase or travel, answer five questions
- Which country, state and local route will you actually use?
- What are the continuous rating, assistance cutoff and independent motor controls?
- Which category and corresponding documents apply to that exact configuration?
- Which rider, equipment, insurance or registration requirements follow?
- Do the path manager and transport operator accept that category?
Do not treat software speed changes, replacement labels or claims about private land as evidence that public road requirements have been resolved. Obtain the destination specific answer before using the bike there.
