The bike rentals were located near the South Gate and you can choose from single bikes or tandems. You can keep the bikes for 100 minutes, which is plenty of time to ride the full stretch. From the wall I had a good view of the city, albeit a smoggy one. I rode along skyscrapers on the one side and traditional Chinese shop fronts on the other. I passed a Buddhist temple in the northwest corner and the lush Huancheng Park just next to it. From the West gate I got a good glimpse of the Drum and the Bell Tower located smack in the centre of the city. One interesting thing was the modest exhibition in one of the watchtowers on the history of the bike. (Did you know the first one was made out of wood?)
After about an hour and a quarter I ended up back to where I started and returned the bike, Ready for a hearty lunch. Because not only is biking a good way to explore new cities, it's also good way to work up an appetite.
