I live in a small town. Most people here traveled around by the bike in the past, and I learn how to ride a bike at an early age. Recently, electric bikes have become more and more popular, so they are convenient and can save energy. There is two in my family. One is for my mom and the another is for my dad. They sometimes allow me to riding them when they send me to buy something, but I seldom ride them. It doesn’t seem strangely for children to do that. The reason where I refuse to do so is that I can’t get used the speed of electric bikes. I prefer walking to riding it.
