E-Bike Laws in Palo Alto, California
Palo Alto may be the most permissive jurisdiction in California on trail access — and the claim carries a caveat. PAMC § 10.64.130 prohibits riding a bicycle on any sidewalk in a business district, and in the University Avenue and California Avenue undercrossings below Alma Street when others are present; it does not mention electric bicycles or classes. Separately, § 22.04.220 reportedly permits all three e-bike classes on paved roads and trails in open space and on both paved and unpaved park trails, with a 15 mph general limit, 5 mph when passing, and mandatory helmet use regardless of age. If accurate, Palo Alto is the only California agency surveyed that permits Class 3 on unpaved park trails.
PAMC § 22.04.220 — permitting all three classes on paved and unpaved park trails, with a 15 mph limit, 5 mph passing and an all-ages helmet mandate — comes from a Town of Los Gatos staff-report survey, a reasonably authoritative but secondary source. It could not be confirmed against the Palo Alto code. If accurate, it makes Palo Alto uniquely permissive on Class 3 dirt-trail access while imposing a helmet requirement broader than state law — an unusual combination worth verifying before relying on either half.
The rules, line by line
| Subject | Rule | Authority |
|---|---|---|
| Business-district sidewalks | "No person shall ride or operate a bicycle upon any sidewalk in a business district." Riders on sidewalks elsewhere must exercise due care and yield to pedestrians. Electric bicycles and classes are not mentioned. | PAMC § 10.64.130 (Ord. 5433 § 2, 2018) |
| Undercrossings | Bicycles prohibited in the University Avenue and California Avenue undercrossings below Alma Street when others are present. | PAMC § 10.64.130 |
| Open space and park trails | All e-bike classes — 1, 2 and 3 — allowed on paved roads and trails in open space and on paved and unpaved park trails. 15 mph general limit, 5 mph when passing, and mandatory helmet use. The speed rule dates to roughly 2001. | PAMC § 22.04.220Citation unconfirmed |
If verified, Palo Alto is the California outlier
Every other agency surveyed bans Class 3 from trails. Palo Alto reportedly permits all three classes on both paved and unpaved park trails.
| Agency | Class 1 | Class 2 | Class 3 |
|---|---|---|---|
| Palo Alto open space and parks ⚠️ | Allowed | Allowed | Allowed, incl. unpaved |
| Santa Clara County Parks | Allowed, paved and dirt | Allowed, paved and dirt | Banned |
| EBRPD | Allowed (~850 mi) | 20 listed paved trails | Banned |
| Midpeninsula Regional Open Space | 2 preserves only | 2 preserves only | Banned |
| Marin County Open Space District | Banned | Banned | Banned |
| Sonoma County Regional Parks | Allowed | Not permitted | Not permitted |
| Sacramento County | Allowed, 15 mph | Allowed, 15 mph | Banned |
| Monterey County dirt trails | Banned | Banned | Banned |
| California State Parks | May be designated | Banned on trails | Banned on trails |
| USFS Lake Tahoe Basin | ~112 mi | Banned | Banned |
The geographic irony is sharp. Palo Alto's own open space reportedly admits Class 3 on dirt, while the Midpeninsula Regional Open Space District preserves immediately adjacent ban e-bikes on essentially all of roughly 160 miles of trail, permitting limited Class 1 and Class 2 access at only two preserves — Ravenswood and Rancho San Antonio.
A rider can cross from one agency's land to the other's with no signage change and go from "all classes welcome" to "prohibited." That is the single sharpest jurisdictional discontinuity found in this survey.
The helmet mandate is the other half
§ 22.04.220 reportedly requires helmet use regardless of age in open space and parks. State law
requires helmets only under 18 (Veh. Code § 21212(a)) and at all ages on Class 3
(§ 21213(b)).
If accurate, that puts Palo Alto in a very small group. Across Northern and Central California only
two regimes impose helmet rules stricter than the Vehicle Code: Marin County and its eleven
municipalities (all ages on Class 2, under the AB 1778 pilot) and Dublin (Ch. 6.73, all under-18
riders of e-bikes and e-scooters, all Class 3 at any age, and under-18 in any city park). Santa Clara
County Parks reportedly requires helmets on unpaved trails, also unverified.
The combination — permit Class 3 on dirt, but require a helmet from everyone — is coherent policy. It trades access for protection rather than restricting both.
The sidewalk provision has the usual gap
PAMC § 10.64.130 traces to Ord. 5433 § 2 (2018), with a lineage running back through prior code
§ 16.22 to ordinances from 1961. It says "bicycle." It does not mention electric bicycles or classes.
Whether it reaches an e-bike is the question that recurs across California — Los Angeles
(LAMC § 56.15, human-powered devices only), Berkeley (BMC § 14.68.010, the old moped standard),
Long Beach, Palm Springs, Watsonville, the City of San Mateo. Only El Segundo and the City of Santa
Cruz have clearly closed it.
The undercrossing rule is more precisely drafted and worth knowing: bicycles are prohibited in the University Avenue and California Avenue undercrossings below Alma Street when others are present. A conditional rule rather than a flat ban, similar in structure to Santa Cruz County's "no pedestrians present" exception.

Common questions
Are Class 3 e-bikes allowed on Palo Alto park trails?
Reportedly yes — PAMC § 22.04.220 is described as permitting all three e-bike classes on paved roads and trails in open space and on both paved and unpaved park trails, with a 15 mph general limit and 5 mph when passing. This comes from a secondary source and is unverified. If accurate, Palo Alto is the only California agency surveyed permitting Class 3 on unpaved trails — every other one bans it.
Do you need a helmet to ride in Palo Alto open space?
Reportedly yes, regardless of age — PAMC § 22.04.220 is described as imposing a mandatory helmet requirement in open space and parks. That is broader than state law, which requires helmets only under 18 and at all ages on Class 3. Unverified, from a secondary source.
Can you ride an e-bike on the sidewalk in Palo Alto?
Not in a business district — PAMC § 10.64.130 prohibits riding a bicycle on any sidewalk in a business district. Elsewhere it is permitted, with a duty to exercise due care and yield to pedestrians. Bicycles are also prohibited in the University Avenue and California Avenue undercrossings below Alma Street when others are present. The section says "bicycle" and does not mention electric bicycles, so its application to e-bikes is textually arguable.
Why do Palo Alto and Midpeninsula open space have opposite e-bike rules?
Because they are different agencies with independent authority under Veh. Code § 21207.5(b), which lets the agency with jurisdiction over a trail prohibit e-bikes by class. Palo Alto reportedly permits all three classes on its own park trails; the adjacent Midpeninsula Regional Open Space District bans e-bikes on essentially all of its roughly 160 miles, allowing limited Class 1 and 2 access at only Ravenswood and Rancho San Antonio. Nothing on the ground marks the boundary.
