Electric motorbike spec sheets in Vietnam carry a two-digit code — IP65, IP67 — that decides how much water and dust the machine is built to shrug off. It is worth reading correctly before a Hanoi monsoon downpour tests it for you.
How the code works
The first digit is solids, the second is liquids. The first digit tops out at 6 — dust-tight. The second digit matters most for riders:
| Second digit | Tested against | Riding translation |
|---|---|---|
| 5 | Water jets from any direction | Rain-riding confidence, but not submersion |
| 7 | Temporary immersion (about 1 m) | Deeper standing water, briefly |
What the verified Vietnamese models carry
Dat Bike publishes IP65 for the Weaver 200 — sealed against dust and low-pressure water jets — and IP67 for the Weaver++, the higher rating matching its newer platform. VinFast’s launch release does not publish IP figures for the scooter line-up, so no claim should be made there: the safe reading for any unverified machine is that its rain tolerance is whatever the manufacturer and warranty say, no more.
What an IP rating does not mean
- It does not mean the charger or charging port is as protected as the bike — never charge in the rain.
- It does not license submersion: flood water past the bottom bracket on an IP65 machine is outside the rating, and moving water hides potholes anyway.
- It is a factory condition, not a lifetime guarantee: crash damage, opened covers and worn seals change reality.
Riding and washing with the rating in mind
Rain riding is a matter of grip and visibility more than electrics on a properly sealed machine — our Hanoi rain guide covers the riding side. Washing should follow the manufacturer’s rules — gentle water, no pressure-washing seals or connectors. And when streets flood, the rating is the wrong tool: our flooded-streets article explains when not to ride at all.
