It is important to stay put until the light facing you has turned completely green. Pushing the pedestrian button does not make the signal turn green any faster. In some intersections, the bike loop is in the middle of the traffic lane. If the loop is in the middle, that s where you should be to make the signal change. Always lock your frame to something that cannot be moved or disassembled.
Many people have their quick-release wheels and seats stolen.
Wheels are most secure when locked with a U-Lock, but a cable will also help deter theft. Secure your bike at home. Consider buying a cheap, used bike for shorter trips around town. Register your bike with the police. This makes it more likely that you will get it back if it is stolen and recovered.
