Mountain bike is the kind with wide tires, many and deep marks, better shock absorption and less effort to ride, which is suitable for rough roads. Non-professional mountain bikes can take people.

City station wagon should be considered as a road racing car, with thin and narrow tires and basically no shock absorption. It's easy to ride, but the handlebars are shallow and the brakes and handlebars are separate. Riding posture is tired, but it is fast and labor-saving, suitable for flat roads. But it is definitely not suitable for riding in rainy days, because the rear fender is too small and mud will splash all over the back. You can't bring anyone.

There is also an ordinary women's bicycle, which is smaller than the old one. It's relatively easy to ride, and it can be packed in baskets, so it's not suitable for women.

The first two kinds of cars are more expensive and easy to be stolen. The latter is economical and practical.

In addition, cycling is a good way to exercise, but it is not recommended to ride a bike in the morning and evening rush hours, because too much automobile exhaust is harmful to your health.

Ps: If you are a male, it is recommended not to ride mountain bikes and road racing cars for a long time, because the seats of these two models are very bad and suitable for professional drivers (they are basically absent, while our non-professional drivers are basically sitting in their seats). Cycling for a long time is easy to cause prostatitis. A friend of mine insisted on cycling to work for two years in order to lose weight and got this.

Since it is less than 20 kilometers, it is recommended to ride a women's car, which is safe, comfortable and durable. Besides, as an office worker, you don't want oil on your pants. The chains of mountain bikes and road racing cars are exposed, so it is easy to get stuck in your pants, because you can't wear professional racing clothes to work.

Of course, there are all kinds of combined cars now, so it is easy and convenient to ride. You can also refer to them

I hope it helps you.
