UPDATE DEC. 8: The post has been updated to reflect the differences between electric scooters and low-powered scooters. Please see CRgov.com/Ebikes for more information.
Castle Rock Town Council enacted a new ordinance making changes to traffic regulations and laws. The revisions, made at Council’s Nov. 4 meeting and now in effect, address the use of electric and motorized vehicles within Castle Rock.
As part of the updated ordinance, Town Council sought to clarify all off-highway vehicles ― to include dirt bikes, unlicensed electric motorcycles and other similar recreational vehicles — are prohibited on Town of Castle Rock streets and roadways, paths, trails and sidewalks. Class 1 and Class 2 electric bicycles are currently the only e-bike classifications allowed on Castle Rock bike, pedestrian and multiuse paths. The new amendments increase penalties and fines for the unlawful use of these vehicles within Castle Rock, including a $250 fine for parents or guardians who knowingly allow their children to drive or ride an off-highway vehicle in Town limits. This applies to all children under 18 years old.
When purchasing an e-bike, it’s important to note the different classifications and rules associated with each to comply with local and State laws. All electric bicycles in Colorado are required to fall under one of three classifications. Each e-bike should have a label showing its classification and other relevant information to include top-assisted speed and motor wattage.

Castle Rock Town Council also adopted new regulations pertaining to golf carts. Under the updated Municipal Code, golf carts are prohibited from driving on Town streets and roadways, paths, trails and sidewalks. With the sole exception of Town usage for business purposes, the only place golf carts may legally operate in Castle Rock is on golf courses. Golf carts do not fall under the category of low-speed electric vehicles; vehicles in that category may be driven on Town streets with a maximum speed limit of 30 miles per hour.
As part of the new ordinance, Town Council also adopted the 2024 Model Traffic Code, a standardized code published by the Colorado Department of Transportation.
