14. Using and Maintaining the Battery Charger
Do not use this charger in an environment of gas and corrosive substances.
Never strongly shake, slam/drop, or throw the battery—damage is likely.
Always protect the battery charger from rain and moisture!
Operating temperature for the battery charger is: 14F-104F (-10°C to +40°C). Do
NOT disassemble the battery charger.
Use only the charger provided with your electric bike. Otherwise, damage could
occur to your battery, battery charger, and void the warranty.
When charging, both battery and charger should be minimum 4 in (10cm) away
from the wall, and in a cool, well-ventilated environment. Place nothing around or
on the charger, while in use!
If the bike is ridden infrequently, or stored long term, put the battery into deep
sleep mode by pressing the battery's power button. Check the battery every
3 months.
While riding, periodically check your battery charge level on your handlebar
mounted Display Panel. If you notice the battery charge is 5% or less, charge
immediately!
Make sure you have a full charge before taking a long trip.
To check the battery charge on the battery itself: Press the button on the end of
the battery case.
If, for example, all 4 lights illuminate—battery is fully charged.
15. Maintaining the Throttle
Take care to protect the throttle from impact or damage. If your bike falls or you
are in a crash, make sure to check the throttle function before riding.
Periodically check that the throttle cable is securely plugged-in to the throttle
body. If not, check and plug it in again.
