My friend also rides a bike, but every time he rides a short route, the road he chooses is wide and smooth. He just bought a mountain bike before, but now he regrets it and feels uncomfortable, so he changed to a road bike. Riding a bike is lighter and more comfortable. He goes out to work by bike and goes shopping by bike.
In fact, another reason is that his strength is relatively small, riding a mountain bike is a bit laborious, and he feels tired after walking not far. So I changed to a road bus. For girls, it is definitely better to choose a bus. After all, your strength is limited, not as strong as many boys.
If the road environment around you is ok, you can choose a road car. On the one hand, it is not very laborious, on the other hand, it also plays a role in fitness. Besides, you don't exercise every day, and it's more convenient to put it on. Secondly, you don't need intensive training, and there is no need to challenge your limits for fitness. Therefore, road cars should be the first choice for ordinary people.
Of course, if you just want to challenge the mountain, you don't have to think about it at all, just buy a mountain bike. Your ambition is there, and indeed mountain bike is more effective for leg exercise and more comfortable for a long time. This kind of car is suitable for people with strength. For example, many soldiers can buy one to exercise after they leave the army.
