E-Bike Rental Defect Injury Demand Letters

Electric bicycle rental defects including battery fires, motor failures, and brake malfunctions cause serious injuries. Navigate product liability claims against rental operators, manufacturers, and component suppliers to recover compensation for burns, fractures, and traumatic injuries.

E-Bike Defect Injury Claims
Defect Type Common Injuries Liable Parties
Battery thermal runaway/fire Severe burns, smoke inhalation, property damage Rental company, manufacturer, battery supplier
Motor surge/sudden acceleration Loss of control crashes, fractures, head injuries Manufacturer, motor supplier, rental operator
Brake system failure Collision injuries, road rash, fractures Manufacturer, brake component maker, rental company
Throttle malfunction Sudden starts, inability to stop, crashes Manufacturer, electronics supplier
Frame/fork structural failure Catastrophic falls, spinal injuries, TBI Manufacturer, materials supplier, importer

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.

  7. Preservation demand: Require defendant to preserve evidence
  8. 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.
Sample E-Bike Defect Injury Demand Letter
[Date] Via Certified Mail and Email Legal Department [Rental Company Name] [Address] AND General Counsel [E-Bike Manufacturer Name] [Address] 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, [Attorney Name] Attorney for [Client Name] [Law Firm] [Address] [Phone] [Email] 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.
