GENERAL WARNING
All sport involves risk of injury or death. In choosing to ride a Stealth Bike, you accept that risk and take responsibility to
learn and practise safe and responsible riding.
This e-bike is sold with a limited warranty against defective workmanship. In some countries it does not conform to federal
motor vehicle safety standards and operation on public roads, streets or highways may be illegal. Before operating this
vehicle, first determine that its use is legal in that given area. It’s your responsibility to familiarise yourself with the laws of
the areas where you ride, and to comply with all applicable laws.
The bike is designed and constructed as an operator only model. The load limit and seating configuration do not safely
permit the carrying of passengers.
This Manual contains several “Warnings” and “Cautions” concerning the consequences of failure to maintain or inspect
your bike and of failure to follow safe riding practices.
In this manual, the WARNING sign indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
Because it is impossible to anticipate every situation or condition which can occur while riding, this Manual makes no
representation about the safe use of the E-bikes under all conditions. By choosing to ride a Stealth Bike, you are assuming
the responsibility for the risks associated with riding. Proper use and maintenance will reduce risk of injury.
WARNING

SAFE OPERATION
Even if you have ridden a bike for years, it is important you read this manual in full before you ride your new bike. Make
sure that you fully understand each section and refer to your dealer if you have any questions.
BATTERY CARE
1. Charge after every use.
2. Exercise caution when removing the battery pack. Always ensure that hands are dry and never insert any object
into the ends of the battery connectors.
3. Do not drop, or throw the battery and avoid puncturing or subjecting the battery to excessive shock loads when not
inside the bike.
4. Do not subject the battery pack to temperatures above 45˚C or below -5˚C.
5. Never leave the battery unoccupied whilst charging.
6. Always disconnect charger when the battery is fully charged.
7. Do not leave the charger connected and switched on for prolonged periods. i.e. days at a time.
BEFORE RIDING YOUR BIKE
1. Always wear an approved helmet when riding and follow the helmet manufacturer’s instructions for fit, use and
care. Stealth Electric Bikes strongly recommend the use of a motorcycle helmet due to the extreme speeds which
can be reached on our bikes. Always wear sturdy footwear which grips to the pedals. Ensure shoe laces and other
loose clothing is safely secured.
2. Obey the local laws. E-bike laws can vary from country to country and from state to state. Please make sure that
you understand the laws regarding the use of electric vehicles in and around your local area.
3. Make sure tyres are properly inflated according to manufacturers’ standards. See page 12
4. Riding with an improperly secured wheel can result in wheel wobble or disconnection to the bike, which can cause
serious injury or death. Therefore, it is essential that you check the wheel fasteners prior to every ride.
5. Not all accessories are compatible with your Stealth Bike. The unique engineering on your e-bike means that only
specially designed and approved accessories should be used. An improperly modified frame, fork, or component
can cause you to lose control. Changing or modifying components without the assistance of a dealer is undertaken
at your own risk.

WHILST RIDING YOUR BIKE
Even though your Stealth Bike has been constructed using the highest quality materials, if you exceed the limit of strength
of your bike or a given part, it may fail. After any high force load, thoroughly inspect all the parts of your bike. High force
loads include crashes, but you don't necessarily have to crash to put a high force load on your bike.
1. Do not ride beyond your limits or the design limits of the bike. If you are unsure of the limits of the bike, consult
your dealer.
2. Avoid improper braking by understanding and practicing proper application of your brakes.
3. Do not ride while intoxicated or while using medications which might affect your ability to ride.
4. Never ride barefoot or in sandals. It is also important to consider the use of gloves, eye protection and body armour
during operation.
5. Do not ride with loose objects attached to the handlebar or any other part of the bike.
6. Do not carry passengers.
7. Never ride your bike whilst holding onto another vehicle.
OFF ROAD RIDING
1. Ride only on designated trails. Avoid large rocks, branches, or depressions. When approaching a descent, reduce
speed, keep your weight back and low, and use the rear brake more than the front.
2. Always respect private property and remember you may be sharing the trail with others. Respect their rights. These
bikes allow you to access many places that are not usually accessible by conventional modes of transport. The high
torque and smooth power delivery helps to minimise the footprint left on loose and slippery surfaces. In some
instances however, there is the potential for the tyres to break traction or slide. Please help to preserve
environmentally fragile areas and help to keep trails open for future use by riding sensibly and avoiding
unnecessary brake slides and wheel spin where possible.

STEALTH BIKE CARE
Stealth Electric Bikes can be ridden in a multitude of environments and weather conditions. While these bikes are water
resistant, care must be taken in exceptionally wet conditions and the bikes must never be submerged in water in any way.
Rain or snow may cause the metal on your e-bike to corrode and also affect the electrical system.
CLEANING
High pressure washers should not be used for cleaning. While the bikes are very well sealed, water ingress may occur as a
result of high pressure water being forced past seals and into electronic components. The preferred method for cleaning is
with a sponge and warm soapy water.
STORAGE
If the bike is going to be stored for periods of more than 3 weeks, it is preferred that the battery is disconnected from the
bike. During prolonged periods of inactivity, the battery should be connected to the charger for 1 hour every month in
order to prolong the life of the battery.
Before storage spray CRC 5.56 into
the motor through the breather
hole (shown on left). Very carefully
lay the bike on its side and rotate
the wheel spraying the CRC into
the motor for two full revolutions.
Once complete, spin the wheel by
hand 10-15 rotations.
Do not expose your bike to extreme highs or lows of temperature. Ideally the bike should be stored at temperatures
between 10˚C and 40˚C.
Avoid storing the bike in wet or damp areas or areas that are prone to extended periods of direct sunlight.
If you have to ship your bike, make sure it is properly packed and protected to avoid damage.
TRANSPORTATION
WARNING: Excessive water exposure will void your warranty. This is an electric bike and all care should be taken to
avoid excessive water exposure.
WARNING: Riding your Stealth Bike in sand will void your warranty. Due to the demands of deep sand on the power
train of the bike, we advise that this bike should not to be ridden in sand.

STEALTH ELECTRIC BIKES 2013 OWNER’S MANUAL

5. Inflate the tires
Tyres should be inflated to no less than 25psi and no more than 40psi. Check the wear and tear on the tyres and replace if
damaged.
6. Charge the battery (Battery charging procedure)
Your battery has been pre tested and will last around 700 charge cycles or 2 years. Performance and mileage of the battery
varies depending on battery temperature, terrain, rider weight, tyre pressure, etc. As with any battery, it has a limited
lifetime however there are some things you can do to increase battery life.
•Ensure battery is fully charged before use.
•Use only the specified Stealth battery charger at all times.
•Recharge at any opportunity (rather than completely discharging battery when not necessary).
•Disconnect the charger when battery is fully charged.
WARNING: Do not disassemble the battery case under any circumstances. Tampering with the battery will void
warranty and could lead to explosions causing serious injury or death.
Check that the seat post does not
collide with shock under full
compression before riding
Loosen rear bolt
Fit clamp to seat rails.
Tighten bolts to get desired
seat angle.

STEALTH ELECTRIC BIKES 2013 OWNER’S MANUAL

Stealth battery packs have no memory effect. This means that they can be recharged or discharged from any state of
charge. Wherever possible keep your battery fully charged.
CAUTION:
The battery charger for your Stealth Bike can operate on dual voltages (120V/240V). Before charging the bike for the first
time, make sure that the red switch on the back of the charger is set to the correct mains power supply voltage for your
region.
i. Ensure the bike is switched off and the charge port is clean and dry.
ii. Connect the charger to the wall socket. A red and a green light should illuminate.
iii. Now connect the charge plug to the charge socket located on the front LHS of the bike. The charger should then
display 2 red lights, and the charge cycle should commence.
iv. The complete charge period should last approximately 2-2.5 hours. At the end of the charge cycle the charger will
illuminate 1 red and 1 green light. This indicates that the battery is fully charged and the charger can be
disconnected.
WARNING: Only use the charger specified by Stealth Electric Bikes. Failure to do so may result in serious injury or
damage to property.
Ensure bike is turned off
Ensure charge port is clean
and dry
A red and green light is
displayed when charger is
disconnected from bike or
battery is fully charged
Connect charger to charge
port
Two red lights are displayed
when battery is charging.
You should also be able to
hear the fan running

STEALTH ELECTRIC BIKES 2013 OWNER’S MANUAL
V 1.2 PAGE | 17
NOTE: It is not unusual to see the red and green lights cycle on and off toward the end of the charge period. This indicates
that the battery is balancing and it is best to wait until the cycling has stopped to get the best from your battery pack.

STEALTH ELECTRIC BIKES 2013 OWNER’S MANUAL
V 1.2 PAGE | 18
YOUR FIRST RIDE
BATTERY BREAK IN
For the first 2-3 cycles, avoid heavy and sudden acceleration in order to minimize the load placed on the battery cells. This
“break in” will help to prolong the life of the battery pack and at the same time help the cells to operate at their full
potential.
THROTTLE
When the power to the bike is switched on, the throttle (located on
the right hand handle bar as shown) can be used to regulate the
electrical power delivered to the rear wheel. The throttle is a split-
twist grip type and provides an increase in power and speed
proportional to the amount that the grip is twisted.
BRAKES
The brakes are sealed hydraulic units. The standard configuration is the same as found on
modern motorcycles with the front brake actuated by the right hand lever and the rear
actuated by the left hand lever – unless requested.
The position of the brake lever may be adjusted to suit personal riding styles.
1. Loosen the torx screws (circled) on the handlebar clamp.
2. Adjust lever to the desired position.
3. Re-tighten the torx screws on the clamp to 4Nm.
4. Check the lever function by squeezing the lever towards the handlebar and ensure the
brake moves freely to stop the bike. If the brake can be pulled to the handle bar, the
brake needs adjustment or servicing.
CAUTION:
Applying sudden or excessive stopping force with the front wheel brake may cause the rear wheel to lift off the ground, or
the front wheel to slip out from under you.
Know the limitations of your brakes. Learn to use your brakes accordingly for every riding surface.

STEALTH ELECTRIC BIKES 2013 OWNER’S MANUAL
V 1.2 PAGE | 19
REGENERATIVE BRAKING
The regenerative braking switch is a red button located between the brake
lever and the gear selector on the left hand side of the handlebars. This can
be used to slow the bike while riding and will increase the range of the
battery.
Note:
The regen braking button can also be used to cut the power to the motor
in case of emergency.
GEAR SELECTOR
Bomber
For pedalling, the Bomber uses a 9-speed sequential gearbox. To shift
gears, the left hand grip may be twisted forward for a lower gear
(when climbing hills) and rearward for a taller gear (for higher speeds).
WARNING: Using regen braking on slippery or loose surfaces such as
gravel, wet grass or wooden bridges could cause the rear wheel to lose
traction and loss of control. Using the regen braking system on this
type of surface is not recommended
WARNING: The pressure on the pedals must be released when shifting gears. Failure to do so may damage your
transmission.

STEALTH ELECTRIC BIKES 2013 OWNER’S MANUAL
V 1.2 PAGE | 20
Fighter
The Fighter is fitted with a 2-speed internally geared bottom bracket. To
shift gears, kick the button found on the cranks to the right for high range
and to the left for low range.
CYCLE ANALYST
The Cycle Analyst displays important real-time information such as
power consumption, battery level, speed and distance.
It can also be used to limit your maximum speed and maximum power
output.
Refer to the Cycle Analyst manual for detailed instructions of how to
use the Cycle Analyst functions. As Cycle Analyst is turned on it
displays its version number, refer to corresponding manual.
How to read your Cycle Analyst (basic version)
After every charge, reset the display by holding down the right button for 3 seconds. "Reset" or “Trip Reset” will flash on to
the screen, depending on CA version, and this will reset the trip statistics from your previous ride.
Assuming that your CA is on the main screen, here's what you need to know.
Once you begin to ride you will see the Watts (W) on the bottom left hand corner of the screen begin to increase. This is an
instantaneous reading of how much power you're using (discharge rate). The more the throttle is turned, the higher the
Watts will be.
The bottom, right hand side of the screen will alternate between Amp-hours (Ah) and distance (m or km) every few
seconds.
WARNING: The pressure on the pedals must be released when shifting gears. Failure to do so may damage your
transmission.
