The school run on an e-bike is a Vietnamese daily ritual — and the smallest passengers need the biggest margins. Here is what the law requires and what practice suggests.

Helmets are required for riders and passengers of powered two-wheelers under Article 33(2) of Law 36/2024/QH15 (pedal-type e-bikes under Article 31(3)) — children riding as passengers are covered. That means a properly fitted child helmet, not an adult helmet perched on a small head: the standard-compliant marking matters at the sizes that exist for kids, and the strap has to be snug enough to survive a head-shake test.

Choosing the machine and the pace

  • The licence-free classes (pedal e-bikes and sub-4 kW mopeds) keep speeds in the 25-50 km/h world — the right territory for carrying children. A1-class machines with a child aboard are legal with the right licence but demand more discipline.
  • The quiet motor is a genuine child advantage: no hot exhaust to touch at stops, no fumes at breathing height, no noise the little passenger has to talk over.

The practical routine

  1. Mount and dismount first, child second. Both feet down, bike braced, then lift the child on and off — never load a child before you are stable.
  2. Feet on the pegs, hands on the rider or grab rail — agree the rules before the first ride and repeat them until habitual.
  3. Shorten every journey — a child passenger halves your safe planning margins: brake earlier, launch gentler, skip the gaps you would take alone. See our two-up guide for the technique.
  4. The silent-ride rules double up: with a child aboard you are invisible and unheard, so position where you are seen.
  5. Weather check: rain means the child needs the same gear you do — dry layers, clear visor or glasses.

One habit above all

Ride as if the child will wiggle at the worst moment — because eventually they will — and build the margins to absorb it.
