Weight figures are useful only when their definitions are clear. A brochure may list dry weight, kerb or curb weight, gross vehicle weight and payload as separate numbers.
Kerb or curb weight
This normally means the scooter ready for normal use, but the included battery, charger, fluids and accessories differ by maker. A removable battery may be included in one listing and excluded in another. Ask for the exact test condition.
Gross weight and payload
Gross vehicle weight is the maximum permitted total of the scooter, battery, rider, passenger, luggage and approved accessories. Payload is the amount the vehicle can carry above its stated ready-to-use weight. Do not add the published payload to gross weight; gross weight is the limit.
Why battery weight changes the comparison
A larger battery can increase range while also increasing loading, braking and tire demands. For removable packs, compare the scooter-only weight and the battery weight separately. A claimed range number does not prove that the frame, brakes or tires are suitable for a heavier load.
What to check before buying
- Is the battery included in kerb/curb weight?
- Does payload include a passenger and luggage?
- Is the gross limit stated by the manufacturer?
- Are tire load indexes, brakes and suspension suitable for that limit?
- Does the warranty exclude overloading?
Use the lower confirmed limit when two sources disagree, and ask the seller for the complete written specification before carrying a passenger or delivery load.
