ODK U500 Electric Bicycle - User Manual

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.
LED Status Guide
!!!! 4 Lights
The battery is between 80% and 100% charged.

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.

Understanding your electric vehicleʼs range
All electric bicycles have a riding range that can vary
greatly depending on how it is ridden, terrain, payload
and wind. After a few rides, you will get a sense of the
vehicles range.
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:
•Pedal to start instead of only using the motor
•Pedaling to help the motor up steep hills
•Reduce speed and pedal along with the motor
•Reduce payload weight
•Properly inflating your tires
•Coast to avoid sudden stops unless necessary
Notice: Riding downhill or pedaling when not using
the throttle will not recharge the battery pack. Do not
over-inflate the tires.

Taking care of your electric bicycle.
Electric bicycles will travel many more miles than
normal bicycles. The weight is heavier and average
speed is much faster than what you may be used to.
As a result, components will wear faster.
Bicycle setup
The bicycle should be lubricated and tuned up
before using it the first time. If you purchased
the bike from the dealer, they will have
performed the basic setup.
Every 100 Miles:
Have the bicycle serviced after the first 100
miles as the parts have had a chance to run-in
and may loosen.
Lubricate the chain and transmission to reduce
the wear on the chain and freewheel. The
chain needs to be lubricated after every ride in
wet conditions.
Adjust brake cable tension and brake pad
clearance.
Check spoke tension every 100 miles
especially on the rear wheel as it handles the
most load. Tighten any loose spokes to prevent
breakage.
Check tire pressure. Properly inflate the tires
within the limits of the tire pressure rating.
ODK U500 Electric Bicycle - User Manual
15

Every 500 miles:
Check for tire wear, replace the tire if the tread
appears to be worn. The rear tire will wear 3x
faster than the front tire as the motor powers
the rear wheel.
Check break pads for wear. Replace brake
pads if they appear worn.
Every 1500 miles:
Have the bicycle cleaned and adjusted by
qualified bicycle mechanic.
Battery care
Charge the battery after every use, even if only used
briefly. Partial charges are not considered full charge
cycles.
Charge the battery at least every 2 months. Storing
the battery for long periods of time will reduce the
storage capacity and/or damage the battery
completely.
Do not leave the battery outside exposed to weather
elements. Charge the battery in a sheltered
environment. Do not store battery inside a car under
direct sunlight
Discontinue the use of the battery if it is damaged for
any reason.
When the battery has reached its lifespan, completely
discharge the pack and take to a battery recycler.

Changing the Rear tire
The tire can be changed without disconnecting the motor
cable. Turn the bicycle upside down and lay it flat on the
ground.
Use a 18 mm wrench to loosen both nuts on the axle. Cut
the zip ties retaining the motor cable to the frame.
Carefully remove the wheel and mount the wheelʼs drive
side to the non-drive side dropout. This will create a work
stand for replacing the tire or tube. Change the tire or tube.
Replace the
wheel into the
normal
position. Use
a wrench to
tighten both
bolts as tight
as possible.
Use zip ties to
secure the
motor cable.
Important Notice!
The nut retaining the axle must be very secure. If
the nut is loose, the axle can spin inside of the
dropout under acceleration. This will damage the
motor wires and the dropout.
