How to use your electric bicycle
The U500 works a lot like a normal bicycle. The main
difference is the inclusion of a battery and motor
system. A twist throttle controls how much assistance
the motor provides. You can pedal along with the
motor to increase the batteryʼs range.
Preparing for your first ride
Be sure the battery is fully charged. Plug the charger
into an 110V electrical outlet and insert the round
connector into the charge terminal on the battery
pack.
The battery may need up to 6-8 hours to charge if it is
fully depleted. The charge is complete when the green
LED is illuminated and the fan stops.
Notice: Always unplug the charger from the AC
power source when not in use.

The battery should be locked to the bike and the key
removed before riding.
Notice: Put the keys in a safe place as it will be very
difficult to get a replacement.
Starting your electric bicycle
Push the red ON/OFF button once. The system will power
up and is ready to ride after about 3 seconds.
Get on the bicycle and pedal to get moving. Slowly twist
the throttle towards you and the electric motor will propel
you forward.

Speed settings
The farther you twist the throttle backwards, the faster
bike will travel.
You can select between Low, Medium and High speed
settings by pressing the MODE button. The
approximate top speeds under the three settings are
shown below.
LOW!10 mi/h (16 km/h)
MED !14 mi/h (23 km/h)
HIGH!18 mi/h (30 km/h)
Applying the brakes
There are two brake levers. The right lever controls
the front disk brake. The left lever controls the rear
disk brake.

Controlling the bike under breaking
When you squeeze the lever, the brake pad will make
contact the disk rotor and reduce the speed of the
bike.
The front brake has more stopping power than the
rear brake. However, the rear brake will give you
more control under braking.
Apply the rear brake first before applying the front
brake for maximum control.
Notice: The brake rotor will become extremely hot for
brief periods after slowing the bicycle down, do not
touch the brake rotor after braking.
When you apply the brakes, the power to the motor
will automatically cut out, the motor will freewheel until
the brake is released and the throttle is activated.
Notice: This system is required at point of sale by
law. The brake cutout system can be deactivated by
the user and will not void the warranty.

Shifting the gears
You can select a comfortable gear to pedal in using
the left twist gear shifter.
Twisting the shifter backward will select an higher
gear for moving at faster speeds. Twisting the shifter
forwards will select a lower gear used for climbing
hills and starts.
Gears can not be changed when the bicycle is
stationary. Reduce pedaling pressure while shifting for
smoother gear changes.
Notice: The motor has a freewheeling clutch which
must be "broken-in" to operate optimally. It will take
more than 100 miles (160 km) before a new rear
motor can spin completely freely when pedaling.

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. The
voltage will decrease temporarily when using the
throttle. This is normal operation.
To read the batteryʼs charge state, let off the throttle.
The display will illuminate to give an indication of the
battery level.

Notice: The batteryʼs charge state can not be read
accurately when using the throttle to propel the
bicycle.
Depleting the battery's charge
Eventually the battery will become depleted when
riding. The power and speed will feel reduced.
It is not healthy for the battery to reach a completely
flat state. The battery will automatically shut down to
protect the cells if it gets too depleted.
Notice: If the battery reaches the shutdown state, the
battery must be removed from the bike to reset the
battery management system before charging. This will
require using the key.
Tip: Use a bicycle speedometer to measure your trip
distance and plan your trips accordingly.
Turning off your electric bicycle
To turn off the electric bicycle, push red ON/OFF
button again. The e-bike will also automatically power
down if not used for 5 minutes.
Recharging the battery pack
Charge the battery after every ride to maintain the
health of your battery. The battery can be charged
even when installed on the bicycle. The battery can
also be removed from the bike and charged at
another location.
Notice: Do not activate the motor when the battery is
charging.

Plug the charger into an 110V electrical outlet and
insert the round connector into the charge terminal on
the battery pack. The battery may need up to 6-8
hours to charge if it is fully depleted.
Important Notice!
If the battery does not began charging (the fan does
not start), the charger will need to be reset. Unplug
the charger from the 110V outlet, wait 10 seconds and
try again.
The more you have discharged the battery, the longer
it will take to recharge. The charger will shut off
automatically when the battery is full.
About the Lithium battery
Your Lithium battery does not have a “memory effect”
associated with older battery technologies. It is highly
recommended to charge your battery after every ride
even if the battery is only lightly used. The battery can
not be overcharged when using the supplied charger.
Charging a partially flat battery is not considered a full
cycle.

component of the electric bicycle. Take care when
