Is Austin a biking city?

Could you elaborate on why you believe Austin might be considered a biking city? Does it have an extensive network of bike lanes and paths? Are there many cyclists on the streets during peak hours? Are there initiatives in place to encourage cycling as a mode of transportation? What about the weather conditions in Austin - are they conducive to biking throughout the year? Lastly, are there any notable bike-sharing programs or other resources available to residents and visitors? I'd be interested to hear your thoughts on these points as they relate to Austin's status as a biking city.
