Nowadays, cycling is becoming a very popular way of getting around cities. A lot of big cities have cycle schemes which allow people to use public bikes. In my opinion, there are advantages and disadvantages to bikes as a form of city transport.
On the one hand, cycling is good for your health. It provides good exercise, and can help you to lose weight and keep fit. It is also cheap, because if you have your own bike, it does not cost you anything to travel around the city.
On the other hand, cycling on busy streets can be dangerous. Car drivers do not always notice cyclists, especially when it is dark, and this can lead to accidents. Therefore, you need to use special lights for your bike.
Finally, cycling is good for the environment, because it does not cause any pollution. and helps keep the air cleaner. If more people used bicycles instead of cars, cities would have cleaner air and less traffic.
In conclusion, I believe that cycling is the best way to travel around cities.
