A common assumption among visitors is that a slow, licence-free e-bike also frees you from a helmet. It does not. Vietnamese law requires helmets for riders and passengers of powered two-wheelers without exception for class.
What the law says
The helmet provision of Law 36/2024/QH15 requires riders and passengers of two-wheeled motor vehicles — mopeds included — to wear helmets that meet the technical standard. The pedal-type e-bike is legally a bicycle, but the helmet obligation follows for powered machines used on the road, and in practice every category of electric two-wheeler sold and ridden in Vietnam is used with a helmet. Children carried as passengers are covered by the same helmet requirement.
Why it matters more on electric
- Speed arrives quietly. A 30 km/h Amio or a 70 km hour Viper does not announce itself, so neither do you — and drivers merging into your lane may not have heard you coming.
- Regen braking is smooth but disc brakes still stop you; in an emergency the helmet is the only thing between your head and the road surface.
- Rental helmets are sized for averages. If you ride daily, own one that fits and is certified.
Buying and keeping a helmet in Vietnam
Proper helmets are inexpensive and widely available in Hanoi. Check the certification marking, replace after any hard impact, and do not store the helmet on the bike in the sun where the shell degrades. Care and replacement guidance is covered in detail in our helmet guide.
