Amazon has begun removing a significant number of e-bike listings from its platform in California after an investigation revealed the company was facilitating the sale of motorized vehicles that far exceed legal speed limits for bicycles. The shift comes in the wake of a targeted inquiry by KCRA 3 Investigates, which found that numerous bikes marketed as “electric bicycles” were capable of speeds that legally categorize them as mopeds or motorcycles.
Under California law, e-bikes are strictly categorized into three classes, with the highest legal speed limit for a pedal-assist bicycle capped at 28 mph. However, the investigation discovered a proliferation of “grey market” bikes sold directly to consumers via Amazon that could reach speeds of 30, 40, or even 50 mph. These vehicles, often lacking the necessary safety certifications, registration, and insurance required for motor vehicles, were being sold and operated on public roads and bike paths.
The crackdown is not limited to Amazon’s internal policy changes. The California Attorney General’s office is now stepping in to target the Direct-to-Consumer (DTC) companies that use major marketplaces to bypass traditional retail safety screenings. State regulators are expected to issue cease-and-desist notices to these manufacturers, warning them that violating state vehicle codes can lead to significant fines and civil lawsuits.
The Gap Between Marketing and Legality
The core of the issue lies in how these vehicles are branded. Many manufacturers list their products as “e-bikes” to attract consumers looking for a low-cost, registration-free commuting option. By avoiding the “moped” or “motorcycle” label, these companies bypass stringent Department of Motor Vehicles (DMV) requirements and safety standards.

KCRA 3’s investigation highlighted a systemic failure in oversight. By purchasing several of these bikes and testing their actual top speeds, reporters found that many exceeded the Class 3 limit of 28 mph by a wide margin. When operated at these speeds, the structural integrity of a standard bicycle frame—and the effectiveness of its brakes—becomes a critical safety concern, as these bikes are not designed for the kinetic energy of high-speed collisions.
Amazon’s response to the investigation was a commitment to ensure that the products sold on its platform comply with local laws. While the company has historically positioned itself as a marketplace rather than a primary retailer for third-party goods, the pressure from state regulators and investigative journalism has forced a more proactive approach to auditing e-bike specifications.
California’s E-Bike Classification System
To understand why these sales are illegal, it is necessary to look at the specific legal thresholds established by the state. California uses a tiered system to determine where a vehicle can be ridden and what equipment is required.

| Class | Motor Type | Max Assisted Speed | Legal Access |
|---|---|---|---|
| Class 1 | Pedal-assist only | 20 mph | Bike paths and roads |
| Class 2 | Throttle-actuated | 20 mph | Bike paths and roads |
| Class 3 | Pedal-assist only | 28 mph | Roads (limited path access) |
| Illegal/Off-Road | High-power motor | Over 28 mph | Private land only |
Vehicles that exceed the Class 3 limit are no longer legally considered bicycles. They are classified as motorized vehicles, meaning they must be registered with the DMV, the rider must possess a valid driver’s license, and the vehicle must be insured. Operating an unregistered, high-speed e-bike on a public street is a violation of the California Vehicle Code.
The Risks of Direct-to-Consumer Sales
The rise of DTC e-bike sales has created a regulatory “blind spot.” Traditional bike shops typically vet the brands they carry to ensure they meet safety standards and legal classifications. In contrast, the Amazon marketplace allows overseas manufacturers to list products with minimal verification of their actual performance specs.
This lack of oversight poses three primary risks to the public:
- Mechanical Failure: High-speed motors placed in frames designed for 20 mph can lead to catastrophic structural failure or brake fade.
- Pedestrian Safety: E-bikes often share paths with pedestrians and slower cyclists; a vehicle traveling at 40 mph in a shared space significantly increases the likelihood of fatal accidents.
- Liability Gaps: Because these bikes are sold as bicycles, owners often do not have the insurance required for motor vehicles, leaving victims of accidents without a clear path to compensation.
The Role of the Attorney General
Attorney General Rob Bonta’s office is focusing on the “source” of the problem. By sending cease-and-desist notices to the companies themselves, the state aims to stop the flow of illegal vehicles before they reach the warehouse. These notices serve as a formal warning that the state will hold manufacturers accountable for deceptive marketing and the sale of non-compliant vehicles.
Legal experts suggest that the AG’s office may use consumer protection laws to argue that selling a “moped” under the guise of an “e-bike” constitutes unfair or deceptive business practices. This could open the door for larger settlements and mandated recalls of non-compliant models already in the hands of consumers.

The next phase of this enforcement action will likely involve the California Product Safety Commission (CPCSB) auditing current inventory and monitoring Amazon’s compliance with the removal of illegal listings. While Amazon has taken initial steps, the state’s focus remains on the manufacturers who continue to exploit regulatory loopholes.
