DUNKED YOUR BIKE?
READ THIS FIRST.
Water crossings happen. What you do next matters. Most e-motos and e-bikes are water-resistant, not waterproof. A brief splash and a submerged battery are two very different situations.
For gas bikes and electric rides alike: get the rider safe first, then assess the bike. Never rush to “see if it still works.”
STOP. DO NOT POWER ON, CHARGE, OR RIDE.
When an electric bike or its battery has been submerged or you suspect water entered its electrical system, do not restart or plug it in. Drying it for a few days does not prove the battery is safe.
01 / Right away / All bikes
First moves. No guesswork.
Safety first
Get people clear of deep water, currents, and possible electrical hazards. Retrieve the bike only when it can be done safely.
Leave it off
Don't crank, power up, charge, or ride a submerged bike. Use controls or disconnect power only when the manufacturer says it is safe to do so.
Record the dunk
Note the bike model, water depth, how long it was underwater, and whether it was fresh, muddy, flood, or salt water. Take pictures from a safe distance.
Isolate a wet battery
If safe to move, keep the bike outside and away from buildings, vehicles, and combustibles (50 feet if possible). Do not bring a submerged battery indoors.
Emergency signs: Smoke, heat, swelling, hissing, popping, or unusual odor? Move away, avoid handling the battery, and call 911. Battery failures can be delayed.
02 / Know the difference
Splashed or submerged?
Rain + shallow splashes
Many bikes are built for normal rain and road splashes, within their manufacturer's limits. Wipe them down, check the manual, and inspect for water intrusion before charging.
Battery underwater, even briefly
Do not charge or reuse the battery. A submerged lithium battery may be compromised even if it looks normal. Contact the manufacturer or qualified shop for safe replacement and disposal guidance.
Salt water and contaminated flood water increase the risk of corrosion and delayed failure. An IP rating for a motor or controller does not automatically apply to the battery or entire bike.
03 / After recovery / Mechanical checks
What to inspect within 24–48 hours
These are mechanical service checks to arrange after the electrical hazard has been assessed. They are not permission to power on or ride the bike.
Bearings + linkage
Have wheel bearings, swingarm pivots, and suspension linkage inspected for water and grit; clean and re-grease or replace as needed.
Brakes
Inspect pads and rotors for contamination or damage. Braking should be tested at low speed only once the bike is cleared to ride.
Chain + controls
Clean and lubricate chain and sprockets. Check cables, throttle, and controls for grit, corrosion, or sticking.
Avoid pressure washing near electrical components, seals, bearings, or connectors. Use the owner's manual for model-specific cleaning instructions.
04 / Gas bikes
Gas bike recovery checklist
- Don't try to start it if the intake or engine may have taken in water; hydrolock can cause damage.
- Ask a mechanic to inspect and drain the airbox, intake, and filter; dry or replace the filter as needed.
- Have the cylinder and exhaust checked for trapped water before the engine is turned over.
- Inspect engine and gearbox oil for contamination; milky oil calls for service. Check the fuel system for water.
- Resume riding only after the engine and brakes have been properly checked.
05 / E-moto + e-bike
Electrical systems need a pro
Battery pack / Highest priority
A submerged pack is a potential fire hazard. Don't charge, open, test, or attempt to dry its internal cells. Arrange qualified assessment and safe disposal or replacement guidance.
Charging port
A wet or corroded charge port can arc or fail. Keep it unplugged. Have it inspected and cleared before any future charging.
Controller + power connectors
Water intrusion may cause corrosion, error codes, overheating, or intermittent power. Have a qualified technician check the wiring and connectors—do not open energized components.
Motor, display + throttle
Water can affect motor wiring, switches, displays, and throttle operation. Have these inspected before attempting to operate the bike.
06 / Getting back out
Return to riding: only after clearance
- Follow the bike and battery manufacturer's instructions. A submerged lithium battery is not cleared just because it has dried.
- Have a qualified service provider determine which parts need repair or replacement and when the vehicle is safe to use.
- Once cleared, check brake function and controls and take a short low-speed test ride in a safe area.
- Watch for delayed corrosion or electrical faults and arrange follow-up inspection as needed.
07 / Prevention
Keep the adventure above water.
Check the manual
Follow the specific bike's water depth and IP-rating guidance. Never assume the whole bike shares one component's rating.
Know what's below
Do not enter water if you cannot see the bottom or judge depth and current safely.
Skip deep crossings
Water can rise around batteries, controllers, and vents as the bike moves. When uncertain, take another route.
NEED A HAND? / BLACKOUT MOTO
TOOK A SWIM? TALK TO US FIRST.
Tell us your bike model, roughly how deep it went, how long it was underwater, and whether the battery got wet. We'll help you identify a sensible next step. For smoke, heat, or other emergency warning signs, call 911 first.
