Speed classes
A kit’s speed class is the class it was built for. Whether you can ride it on a given road is the rule where you are. The bike-match checker uses Great Britain: pedals, 250 W continuous, assistance cut off at 15.5 mph. The long version is the speed class guide.
| Place | Class | The rule in short |
|---|---|---|
| European Union | 25 km/h | EN 15194 pedelec. 250 W continuous. Assistance cuts off at 25 km/h. Pedals required. |
| Great Britain | 25 km/h | EAPC. 250 W continuous rated power. Assistance cuts off at 15.5 mph. The fit checker on this site uses these figures. |
| United States | 20 mph | Class 1 is pedal-assist to 20 mph. Class 2 adds a throttle, still 20 mph. Many states cap motors at 750 W. |
| United States | 28 mph | Class 3 is pedal-assist to 28 mph. A speedometer is commonly required. Watt caps stay with the state. |
| Canada | 32 km/h | Federal power-assisted bicycle. About 500 W, assistance to 32 km/h. Provinces add their own conditions. |
| Australia | 25 km/h | Pedelec. 250 W continuous, assistance to 25 km/h. |
| New Zealand | 300 W | Often regulated at 300 W. Check the current land-transport rule before you buy. |
| Japan | 24 km/h | Assistance fades out by 24 km/h. |
| China | 25 km/h | The national e-bike standard centres on 25 km/h. Watt figures vary by the rule you are reading. |
| EU and Switzerland | 45 km/h | S-pedelec. A registered, insured, plated vehicle. Not an EAPC and not a US Class 3. |
| Private land | Off-road | Motors above the local street class. Photon Pro, X1, BBSHD and direct-drive cargo hubs live here unless a controller is limited. |

Rules differ inside a country. A US class is not a Canadian class, and a GB result is not reused for Northern Ireland or for the EU.
