ZMC888 makes a fair point about Bicycle riding, and I have some good news if you stick to Bicycle ......

You are free to run reds lights you are free to cross a road without looking or stopping and when you do get hit by a car/motorbike you get a free lift to the Hospital with a free check up all paid by the poor guy in his car/bike who tried to get out of your way and tried to warn you with his very loud horn all this don't matter in Chinese Traffic law the small bike is in the right.

TIC and welcome to China.

P.S. should not be chances with Lorry/Buses as these guy don't have good brakes and won't stop to which in this case you will be DEAD.
