Traversing floods with electric motorcycles – is it safe?

Jakarta – Amid increasing flood incidents during the rainy season, electric motorcycle users should refrain from attempting to force their vehicles through deep floodwaters. Yannes Martinus Pasaribu, an automotive expert from Bandung Institute of Technology, noted that although electric motorcycles generally have water protection features, traversing floods still carries the risk of damaging electrical components and batteries.

“Based on research findings, electric motorcycles are generally relatively safe traversing floodwaters up to approximately 20–30 centimetres in depth, or equivalent to the footboard to wheel axle level, provided vital components such as the battery remain unsubmerged,” he stated when contacted from Jakarta on Thursday.

“The risk of component damage remains if forced through deeper water. Electric motorcycles are not recommended for traversing floods, particularly when water reaches electrical components or the battery, as this can damage the system and endanger safety,” he added.

The risk of damage increases if water enters electronic components, the motor, or the battery. Beyond system damage, riders also risk losing control if attempting to traverse floodwaters with a sufficiently strong current.

Should a rider find themselves already in a flooded area, they are advised to switch off the motor and push it slowly towards higher ground without forcing the throttle open.

Battery condition requires particular attention. The various battery types used in electric motorcycles – such as lithium-ion, lithium iron phosphate (LFP), lead-acid, and nickel-metal hydride (NiMH) – are susceptible to moisture. Users must ensure the charger port is tightly sealed and avoid charging whilst the motorcycle remains wet.

For those frequently forced to traverse flood-prone routes, selecting a vehicle with minimum IP67 water resistance certification from the manufacturer is recommended.

Nevertheless, Pasaribu cautioned that water resistance standards vary across brands, making it essential to always verify the water protection specification and warranty coverage for electrical components before purchasing a vehicle.
