Rancho Cucamonga, CA Mobility & Curb Rules: Bike Lane Rules (2026)

020 spells out what counts as unsafe riding: going against traffic on a bikeway, failing to yield, carrying packages that block full control or forward visibility, riders under 18 without a fastened helmet, racing or performing wheelies and stunts near pedestrians or vehicles, and riding faster than is reasonable for the surface and traffic conditions. Riders moving slower than traffic must stay close to the right-hand curb except when passing, turning left, avoiding hazards, or riding on a one-way street. No more than two bicycles may ride abreast off a bike-exclusive lane.

Bicycles and e-conveyances are barred from city park surfaces except paved paths designated for that use, and are barred from every city-owned parking lot (they must be walked, not ridden, in lots). Handheld phone use while riding is prohibited unless the device is hands-free. 050 separately bars leaving a bicycle or e-conveyance in a way that obstructs vehicle traffic, sidewalk travel, or violates a posted no-parking sign. 12: a first violation is an infraction fine up to $100, a second within a year up to $200, a third up to $500, or the city may charge a misdemeanor carrying up to $1,000 and six months in jail.

Officers may impound a bicycle or e-conveyance on the spot if an unaccompanied minor is riding it unsafely in a way that endangers the juvenile or the public; the minor gets a receipt with the pickup location and hours, and an unclaimed device is disposed of or auctioned after 30 days following a pre-disposal hearing.
