Some Denver streets have bicycle lanes, leaving a patchwork of disjointed routes throughout the city. There are over 850 miles of paved, off-road, bike paths in Denver parks and along bodies of water, like Cherry Creek and the South Platte. This allows for a significant portion of Denver's population to be bicycle commuters and has led to Denver being known as a bicycle-friendly city. Some residents are very opposed to bike lanes, which have caused some plans to be watered down or nixed. The review process for one bike line on Broadway will last over a year before city council members will make a decision. In addition to the many bike paths, Denver launched B-Cycle – a citywide bicycle sharing program – in late April 2010. The B-Cycle network was the largest in the United States at the time of its launch, boasting 400 bicycles.
