NightRiders, Incorporated was the first U.S. designated-driver-for-hire service to use collapsible motor scooters, also known as monkey bikes.
Gary Calnan, Brad Dickerhofe, and Carl Grodnik founded NightRiders in July 2001 in Boulder, Colorado.
Before closing its operational doors in 2005, NightRiders earned strong community acceptance as well as garnering a great deal of national media coverage including from TIME Magazine, Inc. Magazine, NBC's The Today Show, Dateline NBC and United In-Flight programming.
Multiple competitor-companies started in the Denver Metro region following NightRiders, often mimicking the company's unique operating and marketing styles.
In August 2005, NightRiders endeavored to expand their concept of driving people home in their own cars.
