How to charge the battery
Charge the battery fully before the first use. The longer you
ride using the battery, the longer it will need to charge.
•Be sure the bike is powered off.
•Plug the 4-pin plug into the rear charger port. It can only
be inserted one way.
•The charger light will turn red while the battery is
charging.
•It takes between 1 and 6 hours to charge depending on
the battery's initial charge level.
•When the pack is full, the charger's light will turn green
and automatically stop charging.
Notice: The charger can get warm during charging. Do not place
anything over the charger while it is charging. Do not use the charger in
wet areas.

Turning the bicycle ON and OFF
The electric bicycle can be ridden like a normal bicycle with
the power turned ON or OFF. However the throttle will be
active only if the power is turned on.
•Locate the power switch on the front face of the battery.
•Flip the power switch to the "ON" position.
•The lights on the display panel will illuminate to give an
indication of the battery’s charge level.
•The bike can now move with the battery power alone.
•The power should be turned off after every ride to avoid
draining the battery.

Using the twist throttle
The motor speed is controlled with a twist throttle similar to a
motorcycle. The farther you twist the throttle backwards, the
faster the bike will travel.
•Sit with a comfortable position on the bicycle's seat.
•Slowly turn the throttle backwards towards you.
•The front wheel will began turning and the bike will move
forward.
•You can pedal along with the motor to increase the riding
range of the battery. However pedaling will not directly
charge the battery.

Using the brakes
The bike comes equipped with front and rear brakes. You
can use the brakes to slow the bicycle down.
•The front brake lever is located on the left-hand side of
the handlebar.
•The rear brake lever is located on the right-hand side of
the handlebar.
•The front brake provides the majority of the bicycle's
stopping capability.
•When slowing down on slippery surfaces, use the rear
brake first before applying the front brake.
•If you use the throttle and the brakes at the same time,
the power to the motor will be automatically disconnected.

Shifting the gears
You can change the gears to find a more comfortable
pedaling cadence when going up hills or riding at a fast
pace. If your bike comes equipped with a 3-speed internal
transmission, the gears can be shifted at anytime.
•The shifter is located on the left side of the handlebar.
•Twist the shifter completely backwards to enter the first
gear.
•Twist the shifter forwards to enter 2nd and 3rd gears.
When starting and going up hills, use the 1st gear.
When pedaling at higher speeds, use the 2nd and 3rd gears.
The power to the bike does not need to be turned on to
change gears. The gear shifter system is a separate system
from the motor and will not alter the motor’s performance.
Notice: Twist shifters are normally mounted on the right side of
the handlebars. On electric bicycles with right-side twist throttles,
the shifter must be mounted on the left and the numbers may
appear inverted.

Using the cruise control
The cruise control system can be used to maintain a
constant speed. It works similar to a cruise control in an
automobile. The cruise control will deactivate if the brakes
are applied, if the throttle is moved, or if the CRUISE button
pushed again. The bicycle will return to normal operation.
How to use the cruise control feature:
•Hold the throttle constant to achieve your desired speed.
•While the throttle is held at a fixed position, push the
"CRUISE" button.
•The LED light will illuminate to indicate that the bike is in
cruise mode.
•The bike will now maintain a constant speed until:
!1. The brakes are applied or
!2. The throttle is moved or
!3. The CRUISE button is pushed again or
!4. The battery is completely depleted

How to read the battery level
There are 4 LED lights on the display panel which will give you an
indication of the batteryʼs voltage. Because the battery gauge
measures voltage, only an approximate estimation of the battery's
state can be obtained. The battery’s voltage can vary greatly
depending on a variety of conditions.
The voltage will decrease temporarily when using the throttle. It
may drop to only 1 light when going uphill regardless of the charge
state. This is normal operation. The voltage will be lower if the
battery has been in a cold environment.
To more accurately read the batteryʼs charge state, let off the
throttle. The display lights will stabilize after 1 second to give an
indication of the battery’s level.
Use this guideline to estimate the battery's charge level:
Let off the throttle to read the Lights
 4 Lights
The battery is between 80% and 100% charged.
3 Lights
The battery is between 40% and 80% charged. Speed will feel reduced.
 2 Lights
The battery level is low and should be recharged soon.
 1 Light
Stop using the throttle, recharge the battery pack.

Understanding the battery's range
All electric bicycles have a riding range that can vary greatly
depending on how it is ridden, terrain, tire pressure,
temperature, payload and wind. After a few rides, you will get
a sense of the electric bicycle’s range capability.
Factors that will decrease your range:
• Rapid accelerations using the motor
• Uphill riding
• Heavy payloads
•Headwinds
• Under-inflated tires
• Extreme hot or cold weather
How to increase your range:
• Start by pedaling instead of only using the motor
• Avoid rapidly accelerating using the throttle
• Pedaling to help the motor up steep hills
• Reduce your average speed and pedal along with the
motor
• Reduce payload weight
• Properly inflating your tires between 40-50 psi
• Coast to a stop and avoid rapid decelerations.
Notice: Riding downhill or pedaling when not using the throttle will not
recharge the battery pack. Do not over-inflate the tires.

Battery Safety Information
About the Lithium battery
Your Lithium battery does not have a “memory effect”
associated with older battery technologies. It is highly
recommended you charge the battery after every ride even if
the battery is only lightly used.
An on-board circuit prevents the battery from over-charging.
The battery can achieve between 500 to 700 charge cycles.
As the battery receives more charge cycles, the capacity will
become decreased. Charging a partially flat battery is not
considered a full charge cycle.
Notice: The battery must be recharged at least once every
month. A battery left unused for several months may result in
permanent capacity loss.
The battery’s capacity will be temporarily reduced in cold
environments. Avoid using the electric bicycle in very hot
weather. Store the electric bicycle in a sheltered place.
Battery Safety Information
• Use only the charger supplied with the bicycle.
• Improper usage can cause explosion or fire.
• Do not short-circuit the battery’s terminals.
• Do not use if the temperature is over 60 C (140 F)
• Do not disassemble the battery pack.
• Do not submerge the battery in liquid.
• Do not set flame to the battery.
• Do not expose battery to freezing temperatures for an
extended period.
