Electric two-wheelers in Vietnam cluster into speed bands, and each band exists for a reason — most of them legal.
25-30 km/h: pedal assistance
Pedal e-bikes cut assistance at 25 km/h by law. VinFast’s Amio, an 800 W pedal-assisted scooter, tops out at 30 km/h. This band is for inner-district trips, school runs and lanes where you would rarely go faster anyway.
Below 50 km/h: the moped ceiling
The 4 kW moped class is defined by a 50 km/h design speed, which is why VinFast sells an Evo Lite deliberately limited to below 50 km/h alongside the standard 70 km/h Evo. For riders without a licence, this is the fastest legal electric format.
70 km/h: swappable-battery commuters
The battery-swap generation — VinFast Evo, Feliz II and Viper — reaches up to 70 km/h with 2,450-3,000 W in-hub motors. That is comfortable city pace, enough for Hanoi ring roads without entering full motorcycle territory.
90 km/h: A1-class electric motorcycles
The Dat Bike Weaver 200 lists a 90 km/h maximum speed from its 6,000 W motor, and the Weaver++ carries the same ceiling. These need an A1 licence and behave like mid-size petrol motorcycles, with 130 km of range at a steady 70 km/h.
Matching the band to your riding
| Band | Licence | Best for |
|---|---|---|
| 25-30 km/h | none | short district hops |
| below 50 km/h | none (16+) | commuting without a licence |
| 70 km/h | none (up to 4 kW) | general city riding |
| 90 km/h | A1 | fast arterials, longer trips |
Speed costs battery: the Weaver 200’s claimed 200 km at 35 km/h falls to 130 km at 70 km/h. Buy the speed band you will actually use, and the range follows.
