The Bicycle & E-Bike Accident Guide

E-Bike Classifications: The National Framework

Most states have adopted a three-class e-bike classification system based on the model legislation developed by PeopleForBikes. California, Colorado, Texas, Florida, Georgia, and over 30 other states use this framework. Understanding your e-bike's class determines where you can ride, what safety equipment is required, and how fault is assigned after a crash.

CLASS 1 (Pedal-Assist Only, 20 mph max): Motor provides assistance only when the rider is pedaling. Allowed on roads, bike lanes, bike paths, and multi-use trails unless locally restricted. CLASS 2 (Throttle-Equipped, 20 mph max): Motor can propel the bike without pedaling. Same access as Class 1 in most states.

CLASS 3 (Speed Pedal-Assist, 28 mph max): Pedal-assist only at higher speeds. Restricted from bike paths and multi-use trails in most states. Minimum age requirements vary (16+ in California, varies by state). Required: speedometer. Recommended: full-face helmet. Class 3 e-bikes face the most legal scrutiny because their higher speed narrows reaction time between cyclists and motorists.

LEGAL IMPACT: Riding within your e-bike's class means the motorist bears full liability for a collision caused by their negligence. Exceeding your class limits triggers comparative negligence. However, exceeding class limits does NOT bar recovery in most states — pure comparative negligence states (California, New York, Florida) allow recovery regardless of fault percentage, while modified comparative negligence states allow recovery below the 50% or 51% threshold.

Dooring Accidents & Anti-Dooring Laws

Dooring — when a vehicle occupant opens their door into the path of a cyclist — is one of the most common and most dangerous types of bicycle crashes. Most states have anti-dooring statutes: California (CVC §22517), Illinois (625 ILCS 5/11-1407), New York (VTL §1214), Texas (§545.418), Colorado (§42-4-1207), and many others. Violation of these statutes constitutes negligence per se — meaning the person opening the door is automatically at fault.

THE PHYSICS OF DOORING: A cyclist traveling at 15-20 mph has virtually zero time to react when a car door opens in their path. The impact launches the cyclist forward — often into traffic where they face secondary collisions with moving vehicles. Dooring crashes produce some of the most severe cycling injuries: facial fractures, TBI from striking the door or pavement, rib fractures from the door edge, and road rash from sliding into traffic.

PROVING LIABILITY: Dooring cases are among the strongest bicycle claims because anti-dooring statutes create per se negligence. Your attorney needs to document: the position of the door (open angle), the bike lane markings showing you were riding lawfully, damage patterns on your bike matching the door edge, and witness statements. Dashboard camera and security camera footage is often available from nearby vehicles or businesses.

THE 'DUTCH REACH': Some jurisdictions are promoting the 'Dutch Reach' — opening a car door with the far hand, which naturally turns the occupant's body to check for approaching cyclists. While not yet legally required, failure to check mirrors before opening a door is powerful evidence of negligence.

Bike Lane Rights & Driver Duties

Every state grants cyclists the same rights and responsibilities as motorists on the road. Most states also have specific statutes requiring drivers to give cyclists safe passing distance — commonly 3 feet, with some states (like Michigan and Pennsylvania) requiring 4 feet.

SAFE PASSING LAWS BY STATE: California (CVC §21760, 3 ft), Florida (§316.083, 3 ft), Texas (§545.053, 3 ft for commercial vehicles, safe distance for others), New York (VTL §1122-a, safe distance), Colorado (§42-4-1003, 3 ft), Georgia (§40-6-56, 3 ft), Michigan (§257.636, 5 ft when speed limit >45 mph), Ohio (§4511.27, safe distance), North Carolina (§20-149, 2 ft minimum). Violation of these statutes creates strong evidence of negligence in a collision.

WHEN CYCLISTS CAN TAKE THE FULL LANE: Virtually every state allows cyclists to take the full lane when overtaking another vehicle, preparing for a left turn, avoiding hazards, or when the lane is too narrow to share safely. A driver who strikes a cyclist legally occupying the full lane bears strong presumptive liability.

DRIVER DUTIES IN BIKE LANES: In all states, drivers may not drive in a bike lane except when making a right turn (and only within a short distance of the intersection), entering or leaving a driveway, or parking where permitted. A driver who strikes a cyclist while illegally driving in a bike lane faces strong presumptive liability.

Helmet Laws by State & E-Bike Class

Helmet laws for cyclists vary dramatically by state and directly affect your claim value after an accident.

TRADITIONAL BICYCLES: Most states require helmets only for riders under a certain age — typically under 16 or under 18. Adults are generally not legally required to wear a helmet while cycling. However, failure to wear a helmet can reduce your settlement through comparative negligence if you suffer a head injury — even though it's not legally required.

E-BIKES: Most states follow the same age-based helmet rules for Class 1 and Class 2 e-bikes as for traditional bicycles. Class 3 e-bikes often require helmets for ALL riders regardless of age (California, Colorado, and others). Riding a Class 3 e-bike without a helmet and suffering a head injury creates significant comparative fault exposure.

THE HELMET DEFENSE IN PRACTICE: Insurance companies routinely argue that unhelmeted cyclists 'assumed the risk' of head injuries. Our recommendation: ALWAYS wear a CPSC-certified helmet. From a safety perspective, helmets reduce the risk of head injury by 48% and serious head injury by 60% (meta-analysis, Cochrane Database). From a legal perspective, wearing a helmet eliminates the most powerful defense argument against cyclists.

Common Cycling Injuries & Settlement Values

Bicycle and e-bike accidents produce injuries that are often more severe than car-on-car collisions because cyclists have no protective shell around them. The most common injuries and their typical settlement ranges:

ROAD RASH: Ranges from minor abrasions to full-thickness skin loss requiring skin grafting. Settlement range: $10,000-$100,000+ depending on severity and scarring. Severe road rash on visible areas (face, arms) commands higher settlements due to disfigurement. FRACTURES: Broken collarbones (the most common cycling fracture), wrists, arms, legs, and pelvis. Settlement range: $30,000-$250,000. Fractures requiring surgical hardware or causing permanent limitation of motion command higher values.

TRAUMATIC BRAIN INJURY: Even with a helmet, the rotational forces of a cycling crash can cause concussions and diffuse axonal injury. Without a helmet, the risk of fatal TBI increases dramatically. Settlement range: $200,000-$3,000,000+. SPINAL INJURIES: High-speed impacts — particularly in dooring or intersection crashes — can cause herniated discs, vertebral fractures, or spinal cord damage. Settlement range: $100,000-$2,000,000+.

DENTAL AND FACIAL INJURIES: Cyclists who go over the handlebars frequently suffer facial fractures, dental avulsions (knocked-out teeth), and lacerations. Dental reconstruction alone can cost $20,000-$50,000. Settlement range: $25,000-$200,000. INTERNAL ORGAN DAMAGE: Handlebar impacts to the abdomen can rupture the spleen, lacerate the liver, or cause internal bleeding. These injuries require emergency surgery and can be life-threatening.

Evidence Preservation for Cyclists

Cyclists face unique evidence challenges because there's no vehicle 'black box' recording your speed, position, or actions before the crash. Building a strong case requires proactive evidence preservation:

YOUR BIKE AND GEAR: Preserve your bicycle exactly as it was after the crash. Damage patterns on the frame, wheels, and components tell the story of the impact — direction, force, and point of contact. Preserve your helmet (impact damage proves head contact), gloves (road rash evidence), and cycling computer/GPS data (proves your speed and route).

STRAVA, GARMIN & RIDE DATA: If you use a cycling app or GPS device, the ride data is critical evidence. It proves your speed (countering 'the cyclist was speeding' arguments), your route (proving you were in a bike lane or lawful position), and the exact time and location of the crash. Export and save this data immediately — cloud services can overwrite or lose data.

CAMERAS: If you ride with a helmet cam or handlebar camera (GoPro, Cycliq, etc.), the footage is often the single most powerful piece of evidence in your case. If you don't have a camera, canvas the area for traffic cameras, business surveillance cameras, and residential doorbell cameras. Request footage within 48 hours — most systems overwrite in 3-7 days.

WITNESS STATEMENTS: Cyclists are sympathetic victims — witnesses often remember the crash vividly. Get names, phone numbers, and email addresses at the scene. Independent witness testimony is 4x more persuasive than party testimony in settlement negotiations.
