see many buses, cars or bikes. It’s very cheap and quick to use bike. If you take a bus, I often have to wait for an hour or so. Besides, the buses move very slowly. The underground is quickly but expensive and often crowded. I used to travel to work by bus. I was often late, and tiring. Then a friend suggested we went to work by bike. I followed him.
