On a petrol bike, the licence question is cubic centimetres. On an electric, it is kilowatts — and the lines are drawn exactly. Under Article 57 of the Law on Road Traffic Order and Safety (No. 36/2024/QH15), electric two-wheelers above 4 kW need an A1 licence (up to and including 11 kW) and an A licence above 11 kW. At 4 kW and under, designed for no more than 50 km/h, the machine sits in the moped class: no licence, rider at least 16. Pedal-assist bicycles whose power cuts at 25 km/h are non-motorised vehicles entirely.
The verified Vietnamese ladder
| Machine | Rated power | Licence position |
|---|---|---|
| VinFast Amio | 800 W, 30 km/h | No licence (pedal-assist class per classification) |
| VinFast Evo | 2,450 W, up to 70 km/h | Moped class — under the 4 kW line |
| VinFast Feliz II / Viper | 3,000 W, up to 70 km/h | Moped class — under the 4 kW line |
| Dat Bike Weaver | 5,000 W, 80 km/h | A1 required |
| Dat Bike Weaver 200 / Weaver++ | 6,000 W (200), 90 km/h class | A1 required |
The instructive row is the Feliz II and Viper: 3,000 W of real power and a 70 km/h top speed, still under the 4 kW line. The moped class is defined by power, not by how brisk the machine feels — and the Evo Lite exists precisely as a deliberately speed-limited version below 50 km/h.
What the ladder means practically
- Buying: check the rated power figure on the official page before assuming a machine is licence-free.
- Renting: an A1-class electric like the Weaver 200 demands the same A1 licence as a petrol 125 — no licence, no ride.
- Fines: riding a machine above your licence class is priced as an unlicensed-ride offence under Article 18 of Decree 168/2024.
