Full Breakdown
Rule 3(g) of the Adams County POSCA Rules and Regulations, Resolution 2022-649, prohibits riding a bicycle, including electric-powered bikes or unicycles, within any Adams County park, trail or open space area except on trails specifically designated for that use, including trails carrying day-of-use or directional designations, and at Riverdale Regional Park. Strollers and wheelchairs are exempt, and people with mobility disabilities may use other power-driven mobility devices under the separate accommodations in Rule 14. Rule 3(c) governs how all trail users, including cyclists, share the trail: every user yields to equestrians, cyclists yield to pedestrians, and a cyclist heading downhill yields to a cyclist heading uphill; yielding requires slowing to a safe speed, being ready to stop, communicating with the other user, and passing safely.
The POSCA Department Director can also post additional use restrictions or closures on specific trails for resource protection or safety, and riding a restricted or closed trail is separately unlawful under Rule 3(b) and (d). § 29-7-101(2), carrying a $100 fine per violation, and an Adams County Park Ranger or sheriff's deputy can eject a rider from the property in addition to issuing a citation.
Violations & Fines
Riding a bicycle off a designated trail, ignoring posted trail closures, or failing to yield under Rule 3's right-of-way order is a civil infraction under C.R.S. § 29-7-101(2). Adams County Park Rangers and sheriff's deputies can issue a citation carrying a $100 fine per violation plus fees and surcharges, and a rider can be ejected from the park or trail regardless of whether a citation is written.
