SAFETY FIRST

If you are unfamiliar with any aspect of this manual, it is advised that you take your SYNERGY KAHUNA and this manual to a local bike shop for inspection, assembly and instructions.

It is extremely important that you follow the safety guidelines contained in this manual in order to ensure maximum safety for you as well as maximum durability of your SYNERGY KAHUNA.
Before you ride your SYNERGY KAHUNA for the ﬁrst time, please be certain that it has been correctly assembled. You will ﬁnd step-by-step instructions in this manual. If for any reason you are not certain, please bring it to your nearest bike shop.
Key assembly steps that much be completed with absolute certainty (including secure fastening) are pedals, saddle height, handlebars (both rotation and height) and wheels.
Please ensure all safety latches, including quick releases and rings, are locked in place and snug without any movement.
Please ensure all bolts (including the front/rear wheels, saddle bolt and brake rotors) are properly tightened. Certain components must be tightened to exact speciﬁcations using a torque wrench for safety assurance. Fixed front wheel axle nut: 28-32Nm, Fixed rear wheel axle nut: 30-35Nm, Handlebar bolts: 6-8Nm, Handlebar stem bolt: 13-15Nm, Bar end bolts: 4-5Nm, Saddle bolt: 22Nm.
Test your brakes prior to using the SYNERGY KAHUNA every time. In wet or icy conditions, use extra caution.
Check your tire pressures frequently. They should be pumped to speciﬁcations stated on tire. This will range from as low as 5 psi up to as high as 35 psi. Low tire pressure will result in damage to the tires and rims. CHECK TIRES FOR SPECIFIC PSI.
Always wear a helmet when riding any bike or e-bike.
Please observe all trafﬁc regulations and other applicable laws.
Don’t drink and ride. Even a small amount of alcohol can impair your judgment and lower your ability to remain safe.
SYNERGY KAHUNA are not toys. All riders must be at least 16 years old.
The SYNERGY KAHUNA is meant to be ridden by a single person. The total recommended weight of a rider, including all items such as a backpack, is 150 kg (330 1bs).
Your SYNERGY KAHUNA is intended for riding on both street and light off-road. Be extra
careful if you decide to use it on other surfaces.
It is advisable to be extremely cautions when riding in trafﬁc. Cars are not used to the speed at which a SYNERGY KAHUNA can travel, as compared to a regular bike.
Since it is impossible to anticipate every situation or condition which can occur while on the SYNERGY KAHUNA, this makes no representation about the safe use of the SYNERGY KAHUNA under all conditions. There are risks associated with the use of any transportation vehicle like a SYNERGY KAHUNA. These risks cannot be predicted or avoided; hence they remain the sole responsibility of the rider.
When you need to replace the battery, please either dispose of it properly or send it back to us or your local bike shop to ensure that it is properly recycled.
Warning: Do NOT take apart OR repair parts by yourself. Please send our service team an email at [email protected], or give us a call for assistance!

ASSEMBLING YOUR SYNERGY KAHUNA

FOR THE FIRST TIME VINTAGE-IRON-CYCLES-2020-Synergy-Kahuna-Cycle-
fig-1

Front Wheel Assembly

Remove the ﬁxed axle by unscrewing the nut on both sides and removing the axle from the wheel. If it is tight, it can be loosened with a 15mm crescent wrench.
Lift the frame/fork and place the front wheel in the bike’s fork.
Make sure that the disc brake is well placed in the middle of the brake caliper.
Because you have hydraulic brakes, be sure NOT to squeeze the brake lever.
Insert the axle all the way through.
Screw the nuts back onto both sides and very securely tighten the wheel using an 15mm crescent wrench. Using a torque wrench, tighten to 28-32Nn. Be sure to also tighten the ﬁxed rear wheel axle nut to 30-35Nm.

If something appears to be wrongly assembled, even if you have followed the instructions, please contact us before riding your SYNERGY KAHUNA.

IMPORTANT: Attach the wheel securely. A loose or detached wheel can cause you to lose control of your SYNERGY KAHUNA and fall and could cause serious injury.

Handlebar Assembly

Straighten the handlebar until is it perpendicular to the ground and lock the handlebar stem safety locking mechanism in place.
Insert the loose handlebar into the handlebar stem with the brakes facing outward and push down. You may raise and lower the handlebar as you wish until you ﬁnd a height comfortable for riding. This means that you can easily reach the brakes for safe control of the SYNERGY KAHUNA. When this is complete, simply pull the handlebar rotation quick release (shown above) backward to secure the handlebars in place. Please ensure the lever is snug and there is no movement.
For safety assurance, tighten the handlebar bolts using a torque wrench to 6-8Nm, handlebar stem bolt to 13-15Nm and end bolts to 4-5Nm.

IMPORTANT : Make sure the handlebar ﬁts tightly into the handlebar rotation quick release, and that the handlebar height quick release and handlebar stem locking mechanism are securely fastened. Failure to do so could result in loss of control of your SYNERGY KAHUNA and could cause serious injury.

Saddle (seat) and Seat Post Assembly

Remove the seat post wrapping.
Loosen the seat post quick release.
Insert the seat post to the desired height before securing it in place with the quick release.
For safety assurance, tighten the saddle bolt to 22Nm with a torque wrench before you ride.

IMPORTANT: Do not raise the seat post above the “minimum insert” line clearly printed on the backside of the seat post. Raising the seat post above the minimum insert line can cause the seat post to fall, which could in turn result in loss of control of your SYNERGY KAHUNA and could cause serious injury.

Assembling the Pedals

Each pedal has an “L” sticker or “R” sticker to indicate left or right side of the SYNERGY KAHUNA. Otherwise, please check the external edge of the pedal body or inside of the pedal axle where the pedal inserts into the crank arm for the imprinted “L” or “R”.
The left pedal is already pre-assembled for you. If you need to remove it, keep in mind that it is removed by turning clockwise, and re-tightened by turning counter clockwise.
To install the right “R” pedal, carefully hand-screw it in, clockwise direction. Use the largest of the allen keys (6mm) provide to tighten the pedal in place. Do this by sticking the allen key into the pedal via the backside of the crank arm and turning counter clock-wise. Alternatively, you can use the 15mm crescent wrench to tighten pedal, turning clockwise.

IMPORTANT: If the pedal does not turn smoothly into the crank, do not force it. Take it back out and try again until it goes in smoothly. In addition, make sure the pedals are tightly attached to each crank arm. Failure to tightly attach the pedals could result in the pedals becoming loose while riding. A loose or detached pedal can cause you to lose control of your SYNERGY
KAHUNA, and fall, potentially leading to serious injury.

How to Adjust Frame-Folding Lever

If your folding-frame lever does not strongly snap into place when locked, or is not ﬂush against the frame, you will need to adjust locking mechanism and/or lever-to-frame distance.
Locking Mechanism
To adjust locking mechanism (perform ONLY if your frame-folding lever does not strongly snap into place when locked or appears to come loose to allow frame to fold):

Slide the mini knob on top of the silver frame-folding lever that releases this handle to open it.
Once opened, locate the very small black pin that protrudes upwards. It is close to the round silver battery-release button.

Now that you’ve located the pin, close the frame-folding lever by pushing it back against the frame.

Grab a small 3mm size allen key and stick it into the tiny hole on the underside of the small black pin. Turn it clockwise. You’ll know it is the correct direction if the pin protrudes upwards.
Keep turning until the pin reaches the lever. You’ll know you’re there when you can no longer turn the pin.

Lever-to-Frame Distance
To adjust lever-to frame distance (perform only if your level is protruding a bit too far out-ward or feels loose):

Slide the mini knob on top of the silver frame-folding lever that releases this handle to open it.
Once opened, locate the large silver button socket cap screw.
Grab a 3mm allen key and stick it into the screw. Turn counter clockwise one-quarter of a turn to bring lever closer to bike and eliminate that loose feeling of the lever.
If you ﬁnd the lever still feels loose or is not ﬂush solid against the frame, try another one-quarter counter clockwise turn and repeat until you get there.
If you ﬁnd lever will no longer close easily, tighten the screw with one-quarter clockwise turns until it’s perfect.

Note: as the folding mechanism is crucial for your safety on the bike, please have a qualiﬁed mechanic double check it for you to ensure that it locks securely especially if you have adjusted it.

FOLDING YOUR SYNERGY KAHUNA

Pull up the handlebar stem vertical locking mechanism on the handlebar safety locking mechanism to fold the handlebar towards the right side of the front wheel.
Remove the key underneath so it is not damaged during the folding process.
- Slide the safety button on the locking mechanism’s folding handle located on the middle of the frame and pull the handle to fold the frame. Hint: you may use your knee to help easily fold the frame.
- Open the seat post quick release lever to lower the saddle, ﬁrst making note of its height using the handy numbered lines on the back of the sear post shaft. Once lowered, re-tighten the quick release so the seat post stays in place.
- Push the pedals inwards to fold them.

IMPORTANT: When folding your SYNERGY KAHUNA, be careful to always turn the front wheel to the left and do not pinch the cables, as this may damage the cables. Damaged cables can result in loss of control of your SYNERGY KAHUNA and could cause serious injury.

UNFOLDING YOUR SYNERGY KAHUNA

Pull up the handlebar stem safety locking mechanism, located on the handlebar stem, to unfold it back to its riding position.
Next push the safety button on the metal folding handle on the frame and pull the handle to unfold the frame so that it locks into place.
Open the seat post quick release lever to raise the saddle to its original height. Once raised, re-tighten the quick release so the seat post stays in place. If it needs to be more ﬁrmly secured, open quick release lever, tighten nut on opposite side lever, then re-close lever. Test to conﬁrm that it’s secure before hopping onto the saddle.
Pull the pedals back into riding position. You will hear a click when they are securely in place.

IMPORTANT: Do not raise the seat post above the “minimum insert” line clearly printed on the backside of the seat post. Raising the seat post above the minimum insert line can cause the seat post to fall, which could in turn result in loss of control of your SYNERGY KAHUNA and cause serious injury.

BATTERY

The battery is the main energy source of your SYNERGY KAHUNA, so be sure to treat it with care at all times. We recommend that your recharge it only with the charger provided with your SYNERGY KAHUNA.
Battery Functions

There are three key positions – on, locked and unlocked.
When the key is turned to the unlocked position, the battery ready to be removed.
In the locked position (which can be found by turning the key one click from the unlocked position), the battery cannot be removed, and motor cannot be switched on.
In the on position (which can be found by turning the key two clicks from the unlocked position), you have full use of your bike’s electronic components. When the key is in the on position, turn the motor and LCD screen on and off by pushing the power button on the display.

IMPORTANT: When parking a SYNERGY KAHUNA, we recommend you lock your battery by setting it on locked position, then remove the key.

Inserting the Battery

Open the SYNERGY KAHUNA frame.
Insert the battery with ignition side facing down.
Close the SYNERGY KAHUNA’s frame.
Insert the key and turn it to locked position.

Removing the Battery

Turn the key to the unlocked position.
Remove the key from the battery/frame.
Open the frame, do not allow the battery to fall out).
Slide the battery out of the frame, using the small ﬁnger hook.
Close the SYNERGY KAHUNA’s frame again.

CHARGING THE BATTERY

IMPORTANT: Do not charge the battery with any chargers other than the one supplied with your SYNERGY KAHUNA. Failure to do so may result in battery damage and will void battery warranty. Follow all instructions provided with the charger supplied with your SYNERGY KAHUNA. Failure to do so could result in damage to your battery or could create a ﬁre hazard that could cause serious injury.
There are TWO ways to charge the battery:
Directly from the bike

Make sure that the key is in the locked position when charging directly from the bike.
Plug the charger directly into the battery first, then diretly into the electrical socket.

Removing the battery to charge

Simply remove the battery from the bike as explained above and plug the charger ﬁrst into the battery, then directly into the electrical socket. For further charging instructions, please refer to enclosed spec sheet inside your charge’s box.

NOTE: For both charging methods, make sure the charger light turns green when plugged into socket, then red when plugged into battery. Once light returns to green, your battery is fully charged. You can then unplug the charger.

CHARGE TIME (FOR BATTERY)

With the provided battery charger,it takes 6 to 8 hours to fully charge 14.5Ah from empty to full (depending on your current battery usage level, climate conditions and earlier charging cycles).
IMPORTANT: If your SYNERGY KAHUNA will be kept for a long period in extreme temperatures (below 0°C/35°F or above 35°C/95°F), remove the battery and keep it in a place where the temperature is between 4°C/40°F and 32°C/90°F.
Do not charge the battery when the air temperature is below 0°C/32°F or above 40°C/ 104°F. Serious damage to the battery could result.

BATTERY USAGE

To reach the furthest distance on one charge, it is recommended to pedal the SYNERGY KAHUNA while the Pedal Assist System is turned ON. It will help save the battery.
When battery power is low while riding your SYNERGY KAHUNA, it is recommended to pedal as much as possible to minimize battery usage so you can get to your destination on the charge that is left on the battery. Charge it as soon as possible if the battery is dead.
Turn off the power when parking. If you decide to push your SYNERGY KAHUNA for any reason, make use of the “walk-assist” option.

SYNERGY KAHUNA BATTERY: IMPORTANT INFO
Type: Lithium battery.
Voltage: 48V.
Capacity: 14.5Ah
Battery lifespan: between 600 and 1000 charges

NOTE for THROTTLE USAGE:

Once the SYNERGY KAHUNA is powered ON and in any level of pedal-assist higher than “0”, when the rider twists the throttle, the SYNERGY KAHUNA will move forward. Do NOT power ON until you are ready to go.
Squeezing the right/rear hand brake, or releasing the throttle, will automatically cut the power to the motor.
When walking with the SYNERGY KAHUNA, you can turn it to “walk-assist” by pressing the assist level arrow down for more than 3 seconds so you don’t automatically turn the throttle on and make the SYNERGY KAHUNA start suddenly.

WARNING: Do not take the battery apart. Do not burn, puncture, submerge in water or damage the battery in any way. Do not use the battery if it appears to be damaged. In case of any noise, irregular heat or leakage from the battery, seize all use immediately. Keep the battery stored in a ventilated place and out of direct sunlight. Keep the battery store above 0° C to avoid excess loss of battery power.

SETTING UP THE SYNERGY KAHUNA

FOR YOUR PERFECT FIT

Saddle Height
To adjust saddle height, open the seat post quick release lever located on the frame where the seat post enters. Once loose, adjust saddle to desired height, then straighten saddle so that it is
centred (parallel to the SYNERGY KAHUNA’s frame). When the desired height is set, ﬁrmly tighten the quick release so that the saddle is securely in place. Try to manually move the saddle from left to right to be sure it is ﬁrmly secured.
IMPORTANT: Do no raise the seat post above the “minimum insert” line clearly printed on the backside of the seat post. Raising the seat post above the minimum insert line can cause the seat post to fail, which could in turn result in loss of control to your SYNERGY KAHUNA and could cause serious injury.
Saddle Position
To move the saddle more forward/backward or adjust the nose of the saddle to point slightly upward/downward, loosen the bolt located under the saddle, at the top of the seat post. You can use one of the allen keys provided. Once loosened, move the saddle to its ideal position. When
the desired position is set, ﬁrmly tighten the bolt to 22Nm for safety assurance. Try to manually move the saddle up/down as well as forward/backward to be sure it is ﬁrmly secured.
Handlebar Height
To adjust the height of the handlebar to match your comfort and riding style, ﬁrst loosen the handlebar height quick release located next to the front end of the frame. Adjust the handlebar to the desired height, making sure to centre the handlebar so that it is perpendicular to the frame. Securely tighten the quick release. Once tight, try to manually move the handlebar from side to side to make sure it is securely in place.

CAUTION : You must slide the handlebar stem connecting the handlebar to the frame in far enough that the series of parallel grooves that mark the minimum insertion level in the tubing are hidden (NOT exposed). DO NOT raise the handlebar higher than this height. If the handlebar stem is not inserted, at minimum, to this line, serious injury can occur to the rider.
Brakes
Disc brakes are pre-installed on both the front and rear wheels for baking control of the bike.
Brake adjustment
Note: Before making any adjustments, double-check that the screws fastening the brake rotors are very tight.
As you ride, your brake pads will start to become thinner. When you notice that braking power
decreases, check the status of your brake pads. Always keep an eye on them so you can replace them the moment they are worn out. If you are unsure of anything relating to your brakes, please take your bike to your local dealer for their expert advice.
CAUTION:

Note which brake lever controls which wheel: left brake lever controls front wheel, right brake lever controls rear wheel.
Be sure to avoid abrupt or strong braking as it can cause you to fall off the bike.

Gears
All SYNERGY KAHUNA’s come equipped with 7 gears. To change gears, simply click the
shifter (one click per gear change) – the higher the gear, the higher the resistance. Change gears to match your peddling comfort level. Be sure to pedal when shifting gears to ensure a smooth gear change. In addition, when climbing steep hills, be sure to lower your gearing. These recommendations will also prolong the life of your drivetrain components.
Pedal-Assist
There are 5 pedal-assist level options with the computer display. When switched to “0”, there is zero pedal assist – complete human power. 5 is the highest level of pedal assistance on the SYNERGY KAHUNA.
Some countries require bikes be equipped with a bell. Be sure to check with your local authorities to learn if you need to install one.

MAINTENANCE

Tire Pressure

Be sure to check it twice a month. We suggest to keep it at 1.4 bar (20 psi). Riding with too low pressure can result in:

Lowered travel range per battery charge
Increased wear on the tires
Increased risk of a puncture
Compromised steering as fat tires with inadequate pressure tend to oversteer.

Squeaking Brakes

The rotor needs to be thoroughly cleaned with a rag dipped in rubbing alcohol to remove any oil or residue.
Pads need to be ﬁled down, usually glazed over from debris on the road. NOTE: When using hydraulic brakes, be sure NOT to pull on the lever while wheel or pads are removed.
If the pads are worn out and less than 0.5mm thick, it’s time to buy new ones.

No Braking Power
This usually occurs because there is not sufﬁcient brake ﬂuid in the braking system. This can be caused by:

A system leak causing ﬂuid to escape. To ﬁx this, please take your bike to your local dealer to ﬁx the leak and replace the ﬂuid.
Bike was turned upside down, causing ﬂuid to migrate to overrun chamber in brake lever. To ﬁx this, return bike to normal position with both wheels on the ground. Then repeatedly pull brake lever until ﬂuid returns back down to the brake calliper.
Brake ﬂuid was contaminated by air, which blocks the braking power to be trans-ferred from lever to calliper. To ﬁx this, please take your bike to your local dealer to either
“bleed” the ﬂuid or replace it.

PRODUCT REPLACEMENT

It is always good to keep spare tires, inner tubes, lube, chains and brake pads on hand as these items are worn out most quickly.
If a product is in need of replacement and you are not completely certain how to do this, it is recommended to take it to your local bike dealer. This includes cables/housing, bearing adjustments, brake adjustment and wheel adjustments. Be sure to replace parts with original SYNERGY KAHUNA bike components to ensure optimal level of performance.
WARNING: As with all mechanical components, the SYNERGY KAHUNA is subject to wear and high stresses. Different materials and components may react to wear or stress fatigue in different ways. If the design life of a component has been exceeded, it may
suddenly fail, potentially causing injury. Any form of cracks, scratches, or change of coloring in highly stressed areas indicate that the life of the component has been reached and it should be replaced.
Failure to repair or replace worn components could reduce your ability to control your SYNERGY KAHUNA and could cause serious injury.

GENERAL TIPS

While our SYNERGY KAHUNA bikes are splash-proof, their electrical components should not be submerged in water. Water damage is NOT covered under the manufacturer warranty, so we strongly discourage any use in the rain..
When washing your bike, use ONLY a damp cloth. Do not spray any water directly on your SYNERGY KAHUNA as it could result in water damage.
To prevent corrosion, dry the SYNERGY KAHUNA and its components after every wet ride. Store bike and battery in a dry location.

IMPORTANT! Do not attempt to open the casings of the battery, motor, or controller. This can be dangerous and will void any warranties by doing so. If you experience a problem, please contact our service department or your local bike shop.
