Battery Basics & Care:
NOTE: Never charge your battery when it’s temperature or the space it is stored in is below freezing. Failure
to follow this rule could result in serious injury, death, and property damage.
The chargers do stop charging when the battery is fully charged. When charging your battery, do not charge
near any potentially flammable material. Charge in a safe fire-resistant space. If you are storing the e-bike
for more than a day, do not leave it plugged in. It is best to leave it charged to 80% but unplugged. The button
on the top of the battery works as a charge gauge. It is not an on-off button. When riding always plug the
charger port with the rubber cover. If moisture gets in, the battery can be destroyed. Everyone is encouraged
to learn a little bit more about the basics of lithium ion battery care and proper treatment. For extended life,
charge your battery to 80% and use it until it is at 20%. Depending on the charge level when plugged in, it
takes 3-6 hours for the battery to fully charge when using the standard charger supplied with the bike.
Charging for 1-2 hours will keep it near 80% depending on last usage. You can check the charge percentage
on the display. If storing for longer periods, it is a good idea to store your battery with a 40-80% charge.
Check the battery once a month. If the battery drops to 25% or lower, charge it up to 40-80%. Recommended
storage temperatures are 50°-77°F and will provide the best performance out of the battery. Storage should
be done in a dry area.

• It is best practice for safety, to only turn on your electric bike once you have lifted your leg over
the bike and are straddling the frame. You should turn it on before you begin riding, but only once
you are ready to ride.
• It is also best practice for safety to turn off the bike when you are done riding after you dismount
from the seat, but before you lift your leg over the bike to get off. If you stop to look at something
or talk with someone, please turn off your bike for safety.
