Miles pedaled on a trainer, stationary bike, or throttle-assisted electric bike are not eligible to be logged in the National Bike Challenge. Miles traveled on a pedal-assisted electric bicycle (devices that provide assistance only when the bicyclist is pedaling) may be recorded in the National Bike Challenge. We recognize that pedal-assisted electric bicycles open the world of bicycling to people who may not be able to ride a traditional bicycle due to fitness, age, or disability. They can also provide a gateway to the use of traditional bicycles. These devices are consistent with the primary objective of the National Bike Challenge, which are to encourage bicycling and promote the health, economic, and environmental benefits that accompany the use of bicycles for recreation and transportation.
