About using Grab bike for foreigners

 All foreigners have to remember these before using Grab bike (or similar such as Gojek, Be):

When they give you a helmet, and then you done, please try to say "xong rồi". They will know and start the trip.

If your weight is more than 80 kgs or 176 lbs, we know that you need a free space between you and the bikers. But please try to sit next to the biker. If you are so heavy, the biker gets difficult to ride because the bike is unbalanced.
