SB 455 rewrites large portions of California’s Vehicle Code for small electric and motorized two‑ and three‑wheeled vehicles. It keeps the three-class e‑bike structure but tightens labeling and manufacturer obligations, creates a new statutory category called “low‑power moped,” and restricts which devices may legally operate on public rights‑of‑way.
Those changes matter to manufacturers, retailers, insurers, local governments, law enforcement, and riders. The bill imposes new permanent markings and certifications, requires written customer notifications for products whose classification changes, sets operator and helmet rules for low‑power mopeds, and criminalizes the operation of any two‑ or three‑wheeled device that is not explicitly defined and authorized in the Vehicle Code.
At a Glance
What It Does
The bill revises e‑bike definitions and labeling, adds a new low‑power moped category with its own marking and operational rules, requires customer notices when a product sold as an e‑bike no longer meets the e‑bike definition, and bars two‑ or three‑wheeled devices not defined in the Vehicle Code from public rights‑of‑way.
Who It Affects
Manufacturers and distributors of e‑bikes and low‑power mopeds, retailers who sold devices as e‑bikes in the last five years, riders (via licensing and helmet rules), local authorities (parking and operational regulation), and law enforcement (new incident‑reporting fields).
Why It Matters
The bill redraws the line between bicycles, e‑bikes, mopeds, and small motor vehicles using wattage and speed thresholds, creating compliance obligations that can force product relabeling, customer outreach, and changes to where and how devices may be used on public streets.

What This Bill Actually Does
SB 455 keeps the existing three‑class structure for electric bicycles but adds concrete production and enforcement hooks: starting July 1, 2026, e‑bikes must carry a permanent, skyward‑facing marking on the frame that lists brand, maker, class, top assisted speed and motor wattage; peace‑officer crash reports must include the same marking information or note its absence. The bill also prohibits selling devices or aftermarket products that change an e‑bike’s speed capability so it no longer fits the legal definition.
The bill inserts a new device class, “low‑power moped,” defined by maximum motor output (gas under 3 gross brake horsepower or electric 2,250 watts or less) and a top propelling speed of 30 mph on level ground. Manufacturers must permanently mark these devices with the brand, maker, top assisted speed, motor wattage and an explicit line stating “this is a low‑power moped, not an electric bicycle.” That marking requirement begins July 1, 2026.Operationally, low‑power mopeds are treated differently from motor vehicles: operators under 18 must hold an M1 or M2 license; adults must hold any valid driver license; operators must wear a bicycle helmet meeting Section 21212 standards; low‑power mopeds may not use sidewalks, paths, trails, or Class I/II/IV bikeways and are limited to highways with posted limits of 35 mph or less where the device can sustain within five miles per hour of that posted limit.
At the same time, low‑power mopeds are exempt from financial responsibility, registration, and license plate requirements and are explicitly not motor vehicles for those purposes.Finally, SB 455 closes a legal gap by barring any two‑ or three‑wheeled device from operating on public rights‑of‑way unless it is explicitly defined and authorized in the Vehicle Code; devices that fail that test are limited to private property or off‑highway use. Taken together, the bill shifts administrative burdens onto manufacturers and retailers, creates new markers for enforcement and crash attribution, and gives local governments express authority to regulate parking and operations so long as their rules don’t conflict with the code.
The Five Things You Need to Know
July 1, 2026 is the effective date for the new permanent, skyward‑facing frame marking requirement for both electric bicycles and low‑power mopeds.
A “low‑power moped” is defined as gas <3 gross brake horsepower or electric ≤2,250 watts and a maximum propelling speed of 30 mph on level ground.
Retailers and manufacturers must provide written customer notification—covering sales in the prior five years—if a product sold as an electric bicycle no longer meets the e‑bike definition as of January 1, 2026.
Low‑power moped operator rules: under‑18 riders need a class M1 or M2 license; adults need any valid driver’s license; riders must wear a bicycle helmet that meets Section 21212.
Two‑ or three‑wheeled devices that are not explicitly defined and authorized in the Vehicle Code may not operate on highways or public rights‑of‑way and are restricted to private property or off‑highway environments.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
E‑bike classes, skyward marking, and excluded vehicles
This section retains class 1, 2 and 3 distinctions, preserves the 750‑watt ceiling for the e‑bike definition, and mandates a permanent, skyward‑facing etching/engraving/label with brand, manufacturer/distributor, classification number, top assisted speed and motor wattage in 9‑point Arial. It expands the excluded list of devices that cannot be advertised or sold as e‑bikes to include vehicles capable of assisting beyond 28 mph and those meeting motor vehicle/moped definitions elsewhere in the code—creating a clearer legal line for advertising and sales enforcement.
Motor‑driven cycle redefinition
Section 405 is amended to make motor‑driven cycle status depend on displacement or motor output: gas engines under 150cc still qualify, and electric machines with output under 10,000 watts that can exceed 40 mph fall into the motor‑driven cycle bucket. The change separates higher‑powered electric two‑wheelers from the e‑bike and low‑power moped regimes, with consequences for registration, equipment, and operator licensing applicable to motorcycles.
Moped (motorized bicycle) definition and buyer disclosure
The moped definition is rewritten around maximum propulsion speed and motor output rather than older gross brake horsepower language. The section also keeps a mandatory, prominent insurance disclosure for buyers—printed on a single sheet in 14‑point boldface—making buyers expressly aware that their existing policies may not cover these devices, which shifts some responsibility to consumers and insurers to verify coverage.
New low‑power moped category and labeling requirement
This added section creates the statutory category “low‑power moped” (electric ≤2,250 W or gas <3 gross brake horsepower; max 30 mph). It requires a permanent skyward marking that includes the statement “this is a low‑power moped, not an electric bicycle,” plus brand, maker, speed and wattage; marking specifications mirror the e‑bike label requirements. By mandating the explicit ‘not an electric bicycle’ line, the bill forces visible, on‑device consumer information to aid enforcement and resale transparency.
Crash reports must capture device markings
This new section requires peace‑officer incident reports for crashes or injuries involving e‑bikes to list all the information from the device’s marking or indicate the marking was unavailable. That creates a structured data point for investigations, enforcement and post‑crash attribution, but its usefulness depends on marking presence and legibility at collision scenes.
Operating rules, licensure, where low‑power mopeds may be used
This article sets operator licensing (under‑18: M1/M2; adults: any class of driver’s license), helmet requirements referencing Section 21212, and roadway access limits: low‑power mopeds can only operate where posted limits are 35 mph or less and the device can sustain speeds within five mph of the posted limit. It also bars sidewalk and certain bikeway use, requires right‑edge lane positioning when possible, and exempts low‑power mopeds from registration, financial responsibility and license‑plate rules—reducing administrative friction while creating potential enforcement gaps related to accountability.
Prohibition on unauthorized two‑ and three‑wheeled devices
This article forbids operation of any two‑ or three‑wheeled device on public rights‑of‑way unless the device is explicitly defined and authorized in Division 1 and elsewhere in the Vehicle Code. Devices failing that test are confined to private property or off‑highway environments. The provision closes a loophole used by novel or imported devices but shifts the burden to manufacturers and sellers to ensure a device fits a statutory category before it’s offered for public use.
Manufacturing standards, tampering and customer notification
Section 24016 ties e‑bikes to CPSC bicycle manufacturing and equipment standards, forbids tampering or modifying e‑bikes in ways that change their legal classification unless labels are updated, bans selling products intended to change an e‑bike’s speed capability, and mandates written customer notices for products sold in the prior five years that as of January 1, 2026, no longer meet the e‑bike definition. These enforcement tools depend on traceable markings and place direct compliance costs on manufacturers and retailers.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Local governments and planning agencies — get explicit authority to regulate local parking and operations of low‑power mopeds, which clarifies zoning and curb management choices.
- Law enforcement and crash investigators — gain a standardized, on‑frame data point and a reporting requirement that can speed vehicle identification and fault analysis after incidents.
- Riders of properly defined e‑bikes — benefit from clearer vehicle classes and stricter limits on higher‑powered or misadvertised products, which helps separate slower pedal‑assist bikes from faster motor vehicles.
Who Bears the Cost
- Manufacturers and distributors — must redesign and apply durable, skyward frame markings, update certification processes to CPSC standards, and potentially relabel or recall products that no longer meet the e‑bike definition.
- Retailers and manufacturers — must perform customer outreach and written notification for affected sales from the prior five years, creating administrative and fulfillment costs and potential liability exposure if notifications are missed.
- Owners and riders of devices reclassified away from e‑bikes — face new operational limits and, for some devices, requirements (or loss of exemptions) that could affect where they can ride and whether different licensing or equipment rules apply.
Key Issues
The Core Tension
The central dilemma is between legal clarity and practical enforcement: SB 455 aims to protect riders and consumers by drawing bright lines (wattage, speed, on‑device markings, and explicit device categories) but doing so creates compliance costs for manufacturers and retailers, practical enforcement problems for police and crash investigators when markings are absent or damaged, and potential gaps in accountability by exempting a new moped class from registration and insurance requirements.
The bill trades definitional clarity for implementation complexity. Wattage and top‑assisted speed thresholds are administrable in theory, but in practice they require durable, legible markings and the ability to test motors and speeds at crash scenes.
Many existing devices on the road lack the new markings; incident reporting depends on a marking being present and readable post‑crash, which is not always realistic. The customer notification requirement for products sold in the prior five years creates additional compliance work and potential disputes over who must notify which owner and how to prove delivery.
Exempting low‑power mopeds from registration and financial responsibility reduces paperwork and lowers barriers for casual use, but it also removes a public registry that helps with theft recovery and accountability. Local authorities get clearer parking and operational control, yet the bill also criminalizes unauthorized on‑road operation of devices not in the code, which could push more enforcement encounters between police and riders of novel micromobility devices.
Finally, the bill’s labeling specs (skyward placement, font size, exact wording) are precise but raise durability and aftermarket‑modification questions—who enforces legibility, and how will courts treat faded or removed markings?
