Why E-Bike Cases Are High-Value
Strict product liability applies to defective products
Battery fires cause severe burn injuries
Higher speeds (20-28 mph) increase crash severity
Multiple defendants with deep pockets
CPSC recalls document known defect patterns
E-Bike Specific Injury Patterns
Second and third-degree burns from battery fires
Facial injuries from over-handlebar ejections
Wrist fractures (both Colles and scaphoid)
Traumatic brain injury from higher-speed impacts
Spinal cord injuries from frame failures
Battery Fire Warning: Lithium-ion battery fires in e-bikes have caused deaths and catastrophic burns. If you experienced a battery fire, the rental company, manufacturer, and battery supplier all face strict liability. These cases often involve fire department investigation reports and may warrant expert electrical engineering analysis.
Legal Framework for E-Bike Defect Claims
Product Liability Theories
Strict Liability
No negligence required: Prove defect caused injury
Manufacturing defect: Unit deviates from design specifications
Design defect: All units share dangerous characteristic
Warning defect: Inadequate safety instructions
Applies to all parties in chain of distribution
Negligence Claims
Negligent maintenance: Rental company failed to inspect/repair
Negligent design: Engineer knew of safer alternatives
Negligent testing: Inadequate quality control
Negligent recall: Delayed or inadequate recall response
May support punitive damages for egregious conduct
E-Bike Rental Company Structure
Company Type
Examples
Liability Notes
Dockless bike-share
Jump (Lime), Citi Bike, Capital Bikeshare
Direct rental operator liability + manufacturer claims
Materials expert: Metal fatigue, manufacturing defects
Human factors expert: Warning adequacy, user interface design
Spoliation Warning: Rental companies often retrieve and repair or dispose of damaged e-bikes quickly. Send a litigation hold letter immediately demanding preservation of the specific unit, all maintenance records, GPS data, battery charge history, and any prior complaints about the same model or unit.

Key Demand Letter Elements
Product identification: Make, model, serial number, rental ID
Defect description: Specific malfunction and how it occurred
Causation: How the defect directly caused the injury
Injury documentation: Medical treatment and prognosis
Damages calculation: Economic and non-economic losses
Preservation demand: Require defendant to preserve evidence
Settlement demand: Specific amount with deadline
Battery Fire Claim Strategy
Strengthening Your Claim
Obtain fire department investigation report
Hire electrical engineering expert early
Search CPSC database for similar incidents
Research any recalls of the battery brand
Document all property damage beyond personal injury
Insurance Coverage Considerations
Rental company's CGL covers bodily injury
Property damage coverage for burned belongings
Manufacturer's product liability policy
Your homeowner's/renter's policy for property losses
Potential umbrella coverage for severe injuries
Punitive Damages: If the manufacturer knew of battery defects and continued selling without adequate warnings or recalls, punitive damages may be available. Document any internal emails, prior complaints, or regulatory actions showing knowledge of the hazard.

Re: Product Liability Claim - E-Bike Battery Fire
Claimant: [Client Name]
Date of Incident: [Date]
E-Bike Model: [Make/Model]
Serial Number: [Number]
Rental ID: [Number]
Dear Counsel:
This firm represents [Client Name] regarding catastrophic burn injuries sustained on [Date] when a rental e-bike's lithium-ion battery spontaneously caught fire during normal operation. We write to demand compensation from all parties in the chain of distribution for this defective and unreasonably dangerous product.
FACTS OF THE INCIDENT
On [Date] at approximately [Time], our client rented an electric bicycle (Serial #[Number]) from [Rental Company Name] at [Location]. The e-bike was a [Make/Model] equipped with a [Brand/Model] lithium-ion battery pack.
Approximately [X] minutes into the ride, while our client was traveling at normal speed on [Street Name], the battery compartment began smoking without warning. Within seconds, the battery ignited in an intense fire that engulfed the rear of the bicycle. Our client attempted to dismount but suffered severe burns to the lower extremities and hands before escaping the flames.
The [City] Fire Department responded (Report #[Number]) and determined the fire originated in the battery compartment. The incident is consistent with lithium-ion thermal runaway, a known defect pattern in e-bike batteries.
PRODUCT LIABILITY ANALYSIS
Strict Liability
The e-bike battery was defective and unreasonably dangerous. Lithium-ion batteries that spontaneously ignite during normal use contain manufacturing or design defects. Both [Rental Company] as the product seller and [Manufacturer] as the product maker are strictly liable for injuries caused by this defective product under [State] law.
Our investigation reveals:
- The [Battery Brand] has been subject to [X] complaints filed with the Consumer Product Safety Commission
- [Manufacturer] issued a voluntary recall of similar battery packs on [Date] due to fire risk
- Industry standards require battery management systems that prevent thermal runaway
- No warnings were provided regarding fire risk during normal operation
Negligence
[Rental Company] negligently failed to:
- Inspect the battery for signs of damage, swelling, or defect before rental
- Remove batteries subject to recall from its rental fleet
- Warn riders of known fire risks associated with the battery model
[Manufacturer] negligently:
- Designed a battery system without adequate thermal protection
- Failed to implement quality control to detect defective cells
- Delayed recall of known defective battery packs
- Provided inadequate warnings regarding fire risk
INJURIES AND DAMAGES
Our client sustained the following documented injuries:
- Third-degree burns to bilateral lower legs requiring skin grafting
- Second-degree burns to hands and forearms
- Smoke inhalation requiring hospitalization
- Permanent scarring and disfigurement
Medical treatment to date includes:
- Burn unit hospitalization ([X] days): $187,000
- Skin graft surgery (2 procedures): $95,000
- Wound care and dressing changes: $23,000
- Physical therapy (ongoing): $12,000
- Compression garments and scar treatment: $8,000
Total medical expenses to date: $325,000
Our client, a [Occupation], has been unable to work for [X] months due to ongoing wound care and limited mobility. Lost wages total $[Amount] with additional loss of earning capacity during recovery.
DEMAND
Based on strict product liability, clear defect evidence, catastrophic burn injuries, and permanent disfigurement, we demand the total sum of $[Amount] to resolve all claims against both defendants. This figure accounts for:
- Past medical expenses: $325,000
- Future medical expenses (scar revision, ongoing care): $150,000
- Past lost wages: $[Amount]
- Future lost earning capacity: $[Amount]
- Pain and suffering (past and future): $[Amount]
- Permanent disfigurement: $[Amount]
We also reserve the right to seek punitive damages if evidence demonstrates knowing concealment of the battery defect.
EVIDENCE PRESERVATION DEMAND
You are hereby placed on notice to preserve and not destroy, alter, or dispose of:
1. The subject e-bike and battery (if recovered)
2. All maintenance and inspection records for the subject unit
3. All battery supplier contracts and specifications
4. All prior complaints, incident reports, or warranty claims involving similar batteries
5. All internal communications regarding battery fire risks
6. All GPS and telemetry data from the subject e-bike
Failure to preserve this evidence will result in appropriate spoliation sanctions.
Please respond within thirty (30) days with your settlement position. If we cannot reach resolution, we will pursue litigation against all responsible parties.
Sincerely,

Enclosures:
- Fire department incident report
- Medical records and billing statements
- Burn injury photographs
- CPSC complaint database results
- Expert preliminary report (if available)
Many e-bikes are manufactured overseas. The US importer or distributor can be held strictly liable for defective foreign products. Identify the company that brought the product into US commerce through customs records or product labeling. They typically carry product liability insurance.
For battery fire cases, yes. An electrical engineering expert can provide a preliminary opinion on the defect mechanism that strengthens your demand. For simpler mechanical failures, an expert may not be needed until litigation. The cost of an early expert opinion often pays for itself in higher settlement value.
