Inflating the Tire
The front tire is inflated when shipped, but it invariably may lose some pressure between the point of manufacturing
and your purchase. Always inflate tire to the correct PSI before first time use.
Lower air pressure can result in a shorter ride time.
Periodically check front tire. Reinflate when needed.
1 Using a bicycle-style tire pump equipped for a
Schrader-type valve, inflate the front tire to the correct
PSI indicated on the sidewall of the tire.

WARNING:
Do not use the electric scooter for
the first time until you have inflated
the tire to the correct PSI. Failure
to do so may damage your electric
scooter and void your warranty.
WARNING:
Do not overinflate, as this could
damage the tire or wheel.
Note: The pressure air supplies
found at gasoline stations are
designed to inflate high-volume
automobile tires. If you decide to
use such an air supply to inflate your
electric scooter tire, first make sure
the pressure gauge is working, then
use very short bursts to inflate to
the correct PSI. If you inadvertently
overinflate the tire, release the
excess pressure immediately.
