Weld County, CO Mobility & Curb Rules: E-Bike Classes (2026)

Weld County Code Article III of Chapter 17 governs conduct on trails owned and operated by the County, and Section 17-3-40(C) opens with a blanket ban: no motorized vehicle may operate on a trail, and any motorized vehicle used on a trail must park only in a designated parking area. 5)(a) and (b), and authorized maintenance vehicles and equipment may be used on a trail. Under the state definitions the county cites, a Class 1 e-bike provides motor assistance only while the rider pedals and cuts off at 20 mph, and a Class 2 e-bike adds throttle-only operation but still cuts off at 20 mph.

Class 3 e-bikes, which assist to a higher top speed, are not named in the exception and are therefore treated as a prohibited motorized vehicle on county trails. The exception applies only to trails the County itself owns and operates; it says nothing about trails inside Greeley, Windsor or the county's other incorporated towns, which set their own rules. Riders must still obey every other prohibition in Section 17-3-40, including the curfew from a half hour after dusk to a half hour before dawn, the ban on discharging fireworks or firearms from a trail, and the five-foot leash requirement for dogs. The Weld County Sheriff enforces Article III under Section 17-3-20, and the County Court hears violations under simplified county court procedure.
