Micromobility crashes produce a defendant problem that ordinary car accidents do not. The driver who turned across your path has insurance, but so might the company that rented you the scooter, and the battery that caught fire after the impact points somewhere else entirely. A Daly City Personal Injury Attorney working one of these cases has to identify every party with a plausible share of fault early, because the rider’s own conduct is the first thing every defendant will point at. Sorting that out starts with a question most riders cannot answer: what is an e-bike, legally speaking?

Does California treat an e-bike like a bicycle or a motor vehicle?

Like a bicycle, provided it fits one of three statutory classes. Vehicle Code section 312.5 defines an electric bicycle as having functional pedals and a motor under 750 watts, then divides them by capability.

• Class 1 assists only while pedaling and stops assisting at 20 mph.
• Class 2 has a throttle and stops powering at 20 mph.
• Class 3 assists only while pedaling and stops at 28 mph.

Class 3 carries extra requirements. Riders must be at least 16, and helmets are mandatory at every age under Vehicle Code section 21213. For Class 1 and 2, helmets are required only for riders under 18 under section 21212. No class requires a driver’s license, registration, or insurance, which is exactly why a serious e-bike collision often has no policy sitting behind the rider.

Modified bikes are a growing problem. SB 1271, signed in 2024, tightened the statutory definition to exclude devices capable of exceeding their class speeds and added battery safety certification requirements tied to recognized standards including UL 2849 for e-bike electrical systems. A bike whose speed limiter was defeated may no longer meet the definition of an electric bicycle at all, which changes the rules that apply to the rider.

What are the rules for standing scooters, and how do they differ?

Motorized scooters are governed separately and more restrictively. Vehicle Code section 407.5 defines them, and section 21235 requires a valid driver’s license, prohibits sidewalk riding, and mandates helmets for riders under 18. Adults have not been required to wear helmets on scooters since AB 2989 took effect in 2019.

Speed and roadway limits matter in crash analysis. Section 22411 caps motorized scooter operation at 15 mph. Section 21235 bars riding on a road with a speed limit above 25 mph unless the rider stays within a bike lane, with local authorities able to permit use on faster streets. A defense lawyer will check both against the crash location before doing anything else.

Who pays when a car causes the crash?

The driver’s liability policy, and often more than one coverage on top of it. The two provisions that decide most of these cases are Vehicle Code section 22517, which prohibits opening a vehicle door on the traffic side unless it is reasonably safe to do so, and section 21760, the Three Feet for Safety Act, which as amended by AB 1909 requires a driver to change lanes when possible to pass a bicyclist and to leave at least three feet when a lane change is not.

Dooring claims are strong because the statute assigns the duty entirely to the person opening the door. Riders should also check their own auto policy. Uninsured and underinsured motorist coverage frequently follows the insured person rather than the vehicle, so an e-bike rider with no car involved may still have UM coverage available through a household auto policy.

Can you sue a rental company after agreeing to the app’s terms?

Sometimes, despite the waiver. Shared scooter and e-bike agreements typically include a liability release and an arbitration clause, and both are enforceable within limits California courts have defined.

Civil Code section 1668 voids contracts that exempt anyone from responsibility for willful injury or violation of law. City of Santa Barbara v. Superior Court (2007) held that a pre-injury release of liability for future gross negligence is unenforceable as against public policy. Claims that a company deployed vehicles with known brake defects, failed to inspect after repeated damage reports, or ignored a pattern of stem failures aim at that opening rather than at ordinary negligence. Pull the version of the terms you accepted, since the arbitration provision and any opt-out window shape what happens next.

When is the crash actually the manufacturer’s fault?

When a component failed rather than a person. California applies strict product liability, meaning a manufacturer can be liable for a defective product regardless of care taken, under the rule from Greenman v. Yuba Power Products (1963).

Battery fires are the clearest example. Lithium-ion cells in thermal runaway ignite rapidly and cause severe burns, and the Consumer Product Safety Commission has issued repeated warnings about uncertified e-bike and scooter batteries and chargers. Preserve the device. A burned battery pack, a fractured stem, or a failed brake caliper is physical evidence, and rental companies collect damaged units quickly. Send a written preservation demand within days.

What if a pothole or broken pavement caused the fall?

Then a public entity is likely involved, and the deadline collapses from two years to six months. Government Code section 911.2 requires presenting a written claim to the responsible city, county, or district within six months of the injury. Government Code section 835 then requires showing the roadway was in a dangerous condition and that the entity created it or had notice with time to repair.

Small wheels make this category worse for scooter riders than for cars. A pavement gap that a vehicle crosses without notice can stop a scooter wheel completely.

How does a Daly City Personal Injury Attorney decide which defendant to pursue?

By running all of them in parallel until the evidence narrows the field. California uses pure comparative negligence, so a jury can assign the rider a percentage of fault and reduce the award without eliminating it. Expect the defense to raise helmet use even where no statute required one, and to argue speed, sidewalk riding, or a defeated speed limiter.

Local terrain shapes the argument here. The grades around Daly City build real speed on a downhill run toward the Mission Street corridor, and shared-fleet permit boundaries generally stop at the San Francisco county line, which affects where a rental vehicle was supposed to be operating in the first place.

If you were hurt riding an e-bike or scooter anywhere on the Peninsula, talk with a Daly City Personal Injury Attorney before returning a damaged rental or accepting the first adjuster’s theory of what happened. The device itself is often the best evidence in the case, and it usually disappears within a week.
