What You Need to Know About E-Bike Legislation for California in 2025

California's 2025 e-bike legislation, stemming from Senate Bill 1271, strictly limits e-bike motor power to 750 watts, sets speed caps by class, and mandates helmet and age restrictions, especially for Class 3 bikes. It bans pedal-less and high-powered e-bikes from sale and road use, ensuring riders comply with traffic laws and safety standards.

How Does California's 2025 Law Define and Classify Electric Bicycles?

California's 2025 e-bike legislation codifies electric bicycles into three distinct classes, each with specific operational and regulatory frameworks. Class 1 e-bikes provide motor assistance only when pedaling, limited to 20 mph. Class 2 e-bikes can operate with motor throttle to 20 mph, also requiring pedals. Class 3 e-bikes assist only when pedaling but can reach 28 mph. Importantly, all e-bikes must have fully operable pedals, excluding any pedal-less designs from legal classification. These classifications dictate usage permissions on roads, bike lanes, and trails.

What Are the Strict Power and Speed Limits Established by the 2025 Legislation?

Under Senate Bill 1271, e-bike motors in California must not exceed 750 watts—including any momentary or surge power peaks. Exceeding this threshold immediately disqualifies the bike from legal street use as an e-bike, rendering it an illegal vehicle unless it meets alternative motor vehicle regulations. Additionally, motor-assisted speeds are capped at 20 mph for Classes 1 and 2, and 28 mph for Class 3. Attempts to modify an e-bike's motor to exceed these speed or power thresholds are prohibited and deemed unlawful.

Why Are Pedal-Less E-Bikes and High-Powered Models No Longer Legal?

The 2025 legislation explicitly forbids any e-bike without fully operable pedals, consequently banning pedal-less electric scooters or throttle-only vehicles from the e-bike category. Furthermore, high-powered e-bikes that exceed the 750-watt and speed limits are no longer classified as e-bikes. Such devices cannot be sold or operated on California streets as e-bikes, aligning with safety and regulatory standards aimed at reducing accident risks and confusion about vehicle classification.

How Do Age and Helmet Requirements Impact Riders of Different E-Bike Classes?

Age and helmet mandates are more stringent for higher-speed e-bikes. Riders of Class 3 e-bikes must be at least 16 years old and wear a helmet at all times, reflecting the increased risks posed by their higher speeds. For Classes 1 and 2, while helmets are strongly recommended, there is no minimum age restriction. These rules emphasize rider safety and aim to mitigate injuries linked to faster e-bike operation.

What Are the Responsibilities of Riders Under the New California E-Bike Law?

Riders must adhere strictly to power and speed restrictions, wear helmets if required (especially for Class 3), and obey all traffic regulations applicable to their e-bike class. It is also essential to remain informed about local ordinances, as municipalities can impose additional limitations on e-bike usage on bike trails and specific paths, especially for Classes 2 and 3. Compliance ensures legal protection and enhances safety for riders and the public.

How Are Retailers and Manufacturers Affected by the 2025 E-Bike Standards?

Manufacturers and retailers face clear prohibitions against selling e-bikes exceeding the 750-watt limit, those lacking fully operable pedals, or those capable of exceeding 28 mph under motor power. This legislative tightening demands meticulous power rating adherence to avoid legal infractions. Retailers must verify compliance to prevent stocking or marketing illegal models, while manufacturers must innovate within these boundaries, balancing performance with legal conformity.

Purchasing Advice

When purchasing an e-bike in California in 2025, ensure the model complies fully with Senate Bill 1271 by verifying it has a motor power rating at or below 750 watts, supports pedal operation, and respects speed limits according to its class. Consider your riding needs—urban commuting, trail riding, or high-speed road travel—to select the appropriate class: Class 1 or 2 for basic needs under 20 mph, or Class 3 for higher speeds up to 28 mph with helmet and age considerations. Always confirm local regulations for trail access and plan helmet purchases to meet safety requirements. Purchasing from reputable brands like HOVSCO, renowned for blending innovation with compliance, can provide additional confidence in both quality and legality.

Q2: Can I modify my e-bike to go faster than 20 or 28 mph?
No, modifications that increase motor power over 750 watts or speeds beyond the class limits are illegal.

Q3: Are pedal-less throttle-only bikes legal in California?
No, pedal-less electric bikes or throttle-only models are not classified as e-bikes and cannot be legally sold or operated.

Q4: Does the power limit include temporary surges?
Yes, any momentary surge exceeding 750 watts disqualifies the bike from being street-legal as an e-bike.
