Is It Safe to Park Your E-Bike in Your Garage?

Are Batteries Safe in Your Garage?

Electric vehicles and ebikes have both been on the rise. EV sales in the U.S. in the first quarter of 2025 saw an 11% increase year-over-year.^[2] And the U.S. e-bike market is predicted to grow 15% from 2023 to 2030.^[3]

Both electric bikes and electric vehicles typically rely on lithium-ion batteries for their power source. These pack a lot of energy into a small space, and they’re often stored in people’s garages. But is that safe?

Are lithium-ion batteries dangerous?

Short answer: They can be, especially low-quality or abused batteries. That said, you can reduce the risk dramatically with good habits.

Thermal runway

While most lithium-ion batteries are safe, if the battery is:

• Damaged
• Poorly made
• Overcharged or
• Charged with the wrong or faulty charger
  
  

Then it can go into thermal runaway. This is a chain reaction where the cell overheats, vents gas and can ignite or explode.

Fire agencies (including FDNY and NFPA) have documented a sharp increase in fires linked to e-bike and e-scooter batteries, some of them fatal.^[4]

What actually makes them risky?

Patterns that show up again and again in incident reports:

• Knockoff or uncertified batteries
• Generic or mismatched chargers
  
• DIY or “makeshift” charging setups and overloading outlets
• Charging in cluttered spaces full of flammable stuff (furniture, cardboard, curtains)

Leaving batteries charging unattended or overnight
There is currently national legislation proposed to help regulate lithium-ion batteries to prevent fires.^[5]

What's Safe to Keep in Your Garage?

Every year, there are 6,600 garage fires in the U.S. that result in an average of 30 deaths, 400 injuries and $457 million in property loss.^[6] Avoiding garage fires starts with being cautious about what you store in there. In addition to being aware of batteries in your garage, what else is safe and unsafe to store?

1. Vehicles and yard equipment (with limits)

Safe to keep:

• Your car, motorcycle, lawnmower and snowblower are designed to live in the garage.
• Small amounts of fuel in their tanks are expected and covered by building/fire codes.

Just don’t:

• Store extra fuel in random containers (only in approved fuel cans).
• Park hot equipment on top of piles of cardboard, rags or sawdust.
  
  

2. Tools, hardware and “garage-friendly” storage

Safe to keep:

• Hand and power tools
• Nails, screws hardware organizers
• Outdoor gear and sports equipment
• Holiday decorations (in sealed plastic bins)
• Camping gear, coolers, ladders, etc.

These items tolerate temperature swings and don’t add much fire risk on their own.

In a typical residential garage, these categories are usually fine.

If Your Garage Explodes, Who Covers Damages—Home or Auto?

Let’s say an e-bike battery, a gas can, or another stored item ignites or explodes in your garage and causes major damage. Your garage structure burns and, if it’s an attached garage, potentially even spreads to your main home. The stuff inside the garage is damaged. Your car itself is heavily damaged or even totaled. 

Is it home or auto insurance, or some combination of both, that protects you in this circumstance?

1. Damage to the garage and the house → Homeowners insurance

A standard homeowners policy generally covers:

• Your dwelling (the house itself and attached garage) under Dwelling Coverage
  
• A detached garage under Other Structures coverage
• The contents of the garage (tools, bikes and camping gear) under Personal Property coverage

Fire and explosion are classic “covered perils” in most homeowners policies.

So if a battery or a gas can causes a fire, your homeowners insurance will usually:

• Pay to repair or rebuild the garage and any other damaged parts of your home
• Replace or reimburse personal property ruined in the fire (up to your coverage limits)

You’ll still have:

• A deductible
  
• Possible limits on certain categories (tools, business equipment, etc.)

Most policies cover accidental fires even if you were a bit careless (e.g., overloading a circuit), as long as it wasn’t intentional or fraudulent.

2. Damage to your car → Auto insurance (not homeowners)

Here’s the piece a lot of people miss:

• Homeowners policies generally exclude motor vehicles that must be registered for road use (cars, trucks, and regular motorcycles) from personal property coverage.
• Your car is usually protected by your auto policy, not your home policy.

However, in order for your vehicle to be covered by car insurance in the event of a garage fire, you must have comprehensive coverage.  Comprehensive coverage typically covers fire and explosion damage to your vehicle, whether the fire started:

• In the house
• In the garage
• In the car itself
• In a wildfire

If you only have liability-only auto insurance (no comprehensive, no collision), you’re usually out of luck on damage to your car in a garage fire.

3. What about the e-bike and its battery?

This one depends on how your insurer classifies the e-bike:

• Some insurers treat low-speed e-bikes as bicycles/personal property, so fire or theft could be covered under homeowners or renters insurance (again, limits and deductibles apply).
• Others treat them more like motor vehicles and may exclude them from standard homeowners coverage—especially fast or moped-style models. You might need a special endorsement or separate policy.

Even if the bike itself is considered excluded, the damage it causes to the home is often still covered. Think of it like a candle that starts a fire; the candle isn’t the item being insured, the house is.

4. Liability if the fire hurts someone else

Now that we've covered your things, what happens if the fire or explosion in your garage: 

• Damages your neighbor’s property or
• Injures someone (guest, delivery driver, etc.),

In these cases, your personal liability coverage under homeowners insurance may step in if you’re found negligent (for example, storing large quantities of fuel against code).

Auto liability is more about injuries and damage arising from the use of your car, not a random garage fire, so it would be unlikely to be useful here.
