"Discover Denver by B-Cycle B-Cycle stations are scattered around Denver, which makes it easy and affordable to bike the city. For 24 hours, it is only $9 to rent a bike and bounce between stations. There are incremental fees if the bike stays out longer than 30 minutes so be alert and swap bikes at a station if time is running up. The Greenway Trail along the South Platte River is a peaceful way to traverse the city while feeling removed in nature. Make sure to enjoy the parks and read the historic plaques along the path to learn about the early history and geology of the area."
