Using a bike in San Francisco
Bikers have a strong representation in San Francisco making it possible for many to opt for bikes to beat the traffic. Bikers rights are recognized and bikers are respected by other vehicles. You'll also find bicycle lanes on the streets.
Market Street is one place where you can see the most prominent usage of bicycles. When you're tired, you're allowed to take your bike onto a public transport system during non-peak hours. Rush hour in this sense includes the morning hours between 7 -9 am and evening hours between 5-7 pm.
