Danville's new e-bike rules take effect Thursday, and they are stricter than what town staff originally recommended.
The Town Council adopted Ordinance No. 2026-02 on July 7 by a 5-0 vote. Beginning Aug. 6, anyone riding an electric bicycle, an electric motorcycle or a motorized scooter inside a Danville town park has to dismount and walk the device. Riders can still bring the machines into parks. They cannot ride them there, anywhere in the park, at any speed.
The ordinance does two other things. It sets a 15 mph speed limit for bicycles, e-bikes, e-motorcycles and motorized scooters on town-owned trails outside of parks. And it broadens the existing prohibition on negligent or reckless riding so that it covers all wheeled vehicles on town parks and trails, not just some categories.
The council introduced the ordinance on first reading in June, also unanimously, then adopted it in July.
Why it exists
Danville has been arguing about this for close to two years, and the arguments got specific.
At the June meeting, resident Jenny Phillips told the council she had been struck by an e-bike about four weeks earlier and suffered a broken finger that was partially amputated. She said the police report found the rider at fault but concluded he could not be cited, because he was riding on a town path where no applicable rule existed.
That gap is what the ordinance is meant to close. Mayor Newell Arnerich made the enforcement logic plain when the council took it up, saying the value of the rule is that it is unambiguous. Either you get off the bike or you do not, and if you do not, you can be cited. It does not require an officer to determine what class of bike someone is riding.
That last point matters more than it sounds. State law splits e-bikes into three classes. Class 1 is pedal-assist with motor help ending at 20 mph. Class 2 has a throttle with assistance up to 20 mph. Class 3 is pedal-assist up to 28 mph, requires a speedometer, and is limited to riders 16 and older. Anyone under 18 has to wear a helmet on any class, and all Class 3 riders must wear one regardless of age.
Sorting that out at the roadside is difficult, and it is harder still with the throttle-driven electric motorbikes now common on Danville streets. Local safety advocates have argued that many of these machines exceed the power and speed limits California sets for e-bikes even though they are marketed and sold as e-bikes. Volunteers with Danville Safety Advocates and E-Bike Access told the council they counted more than 200 of them at seven San Ramon Valley middle schools.
Residents pushed the council to go further than what staff and the Parks, Recreation and Arts Commission had recommended, and the council revised the ordinance before adopting it. The result appears to be among the most restrictive e-bike rules any East Bay city has adopted. Dublin and Livermore prohibit sidewalk riding. Most East Bay cities defer to state law and stop there.
Enforcement, and the grace period
The town says its first move is education, not tickets. Over the coming weeks Danville plans to install signage at town parks, push information through its own communication channels, and work directly with the San Ramon Valley Unified School District and individual schools to reach students and families before classes resume.
That does not mean nothing happens on Aug. 6. Danville police already issue fines and impound e-bikes and motorbikes when children are caught riding illegally, including reckless riding in parks and riding above posted limits. The new ordinance gives officers a clearer basis to act.
The timing is deliberate. The rule lands days before the school year starts, when e-bike traffic around middle and high school campuses spikes.
What this changes for your family
If your kids ride to Osage Station Park, Sycamore Valley Park, Hap Magee Ranch Park or any other town park, the rule is the same at all of them: off the bike at the park boundary, walk it while you are inside.
If they ride on town trails outside parks, the ceiling is 15 mph. That is slower than a Class 2 e-bike's assisted top speed and well under a Class 3's, which means a rider who simply lets the motor run at its limit is over the line.
Separate rules still apply downtown. It remains illegal to ride an e-bike, electric scooter or electric skateboard on sidewalks in the downtown area and other designated business and commercial districts.
