Motorbikes
There are many motorbikes. Hanoi, the capital, has 3.5M people and 2M motorbikes.  There doesn’t seem to be any laws relating to these motorbikes – crash helmets are a rarity, children often stand up, they often carry up to 5 passengers (sometimes 5 adults), carry what you like no matter what size, even a coffin..

Bikes
There are also many bikes, especially in the country. We didn’t see any children’s size bikes – all bikes seem to be the same size and the children have to manage. Often one pushes and another rides as they can’t reach the pedals.
