It depends on your purpose and function. There are many scooters now, but it is not recommended. If you really have plenty of money, you can buy a QQ, which is good for both work and leisure. However, if you don't have enough money, you can only buy a tricycle, which can not only pull goods, but also walk instead of walking. However, in many cities, three-wheeled roads are forbidden, so I hope to adopt it.
