(1) CONDITIONS THAT EFFECT BATTERY RANGE
Ambient temperature: Extreme cold and heat can deplete the battery's charge more quickly.
Number of charges/discharges: The more charge/discharge cycles the battery has undergone, the less capacity it will
have.
Headwinds: Riding into a strong headwind will cause the motor to use more energy.
Road conditions: Hilly and rough terrain will cause the motor to use more energy.
Luggage: Carrying extra luggage on the carrier or in a backpack will cause the motor to use more energy.
Rider weight: A heavier rider will cause the motor to use more energy than with a lighter rider.
Acceleration from a standing stop: Since more energy is used during initial acceleration, riding in conditions that force
you to start and stop often (i.e. city traffic) will cause the motor to use more energy.
Proper gear usage: Pedaling in the correct gear for the terrain will help save energy for both you and the battery.
Poor maintenance: A dry or dirty chain and under-inflated tires can cause the motor to use more energy.
(2) To help maintain maximum range
Charge the battery under room temperature 0 ~ 40 degrees C. ( 32~104 degrees F )
Discharge the battery as much as possible before recharging.
Refresh-charge (Twist 2.0) after every 15 normal charges, but at least once every 3 months.
Use the gears while accelerating or riding uphill.
Don't ride with under inflated tires and keep the chain clean and well lubricated.
(3) Battery Tips Approximate life
Twist 1.0 is equipped with Li-Ion batteries. If used and maintained properly they should last at least 600 charging
cycles.
Twist 2.0 is equipped with Ni-MH batteries. If used and maintained properly they should last at least 500
charging cycles.
If the range per charge becomes too short, even after refreshing the battery (Twist 2.0), the battery's life may
have come to an end. Replace the battery with a new one.
(4) For extended storage
Charge the battery to full level.
Recommended storage temperature: -20 ~ 30 degree C. ( -4 ~ 86 degree F )
Charge the battery every 3 months.
