Safety & Warnings
Cycling can be a hazardous activity even under the best circumstances. Providing proper maintenance to your electric bike is your responsibility as it helps to reduce the risk of injury.
This manual contains many warnings and cautions concerning the consequences of failure to maintain or inspect your electric bike. Many of the warnings and cautions say, “You may lose control and fall” and that can result in serious injury or even death.
The warning of possible injury or death will not be repeated whenever the risk of falling is mentioned.
Important Safety Information
There are many things you can do to protect yourself while riding. Recommendations and safety tips are offered throughout this manual including the following:
Always Wear A Helmet
Helmets can significantly reduce the possibility and severity of head injuries. Always wear a helmet that complies with your state laws when riding the Electric Bike.
Check with your local police department for requirements in your community.
Do not wear loose clothing that can become tangled in the moving parts of the Electric Bike. Wear sturdy shoes and eye protection. Check your state laws concerning other protective wear that may be required when riding the Electric Bike.
Know Your Electric Bike
Your new Electric Bike incorporates many features and functions that have never been built into a bicycle before. Read this manual thoroughly to understand how those features enhance your riding pleasure and safety.
Ride Defensively
One of the most common cycling accidents is when the driver of a parked car opens his door into a rider's path. Another common occurrence is when a car or another cyclist moves suddenly into your path.
Always be aware of other vehicles around you. Do not assume that drivers or other cyclists see you. Be prepared to take evasive action or stop suddenly.
Make Yourself Easy to See
Make yourself more visible by wearing bright reflective (high visibility) clothing. Keep your reflectors (not included) clean and properly aligned. Signal prior to turning so that drivers and other cyclists can anticipate your actions.
Ride Within Your Limits
Take it slow until you are familiar with the conditions that you encounter. Be very careful in wet conditions as traction can be greatly reduced and brakes become less effective.
Never ride faster or beyond your riding abilities. Remember that alcohol, drugs, fatigue and inattention can significantly reduce your ability to make good judgements and ride safely.
Keep Your Electric Bike in a Safe Condition
Follow the inspection and maintenance guidelines beginning on page 12. Check critical safety equipment before each ride.
Know the Law
Cyclists are required to follow the traffic rules. Additionally, some communities regulate the use of motorised bicycles regarding minimum age requirements and necessary equipment. Check with your local police department for specific details.
Correct Frame Size
When selecting a new bicycle, the frame size is a very important safety consideration. Most full-sized bicycles come in a range of frame sizes. These sizes usually refer to the distance between the centre of the bottom bracket and the top of the frame seat tube.
For safe and comfortable riding, there should be a clearance of not less than 3-5cm between the groin area of the intended rider and the top tube of the bicycle frame, while the rider straddles the bicycle with both feet flat on the ground.
The ideal clearance will vary depending on the type of bicycles and rider preference. This makes straddling easier when off the seat and safer in situations such as sudden stops.
Checking the Battery Pack Before Using for the First Time
The battery pack is partially charged. To ensure full battery pack capacity, completely charge the battery pack before using it for the first time.
Battery care:
- Even with proper care, rechargeable batteries do not last forever. Every time the battery is discharged and subsequently recharged, its relative capacity decreases by a small percentage. You can maximise the life of your battery by following the instructions. Battery should be fully charged till recommended charge times immediately when they are received.
Li-LON recommended charge time: 5-6 hours
- For a complete, 100% charge, leave the battery on the charger for one full hour after the charger indicator light turns green.
- Never charge batteries for more than 18 hours straight.
- Li-ion batteries do not have a “memory”. Partial discharge/charge cycles will not harm the batteries' capacity or performance.
- The rated output capacity of the battery is measured at 25°C. Any variation in this temperature will alter the performance of the battery and shorten its expected life. High temperatures especially reduce overall battery life and run time.
- Always be sure to turn the bike power switch to “OFF” after every use. If you leave the power switch in the “ON” position or your product has not been charged for a long period of time, then the battery may reach a stage at which they will no longer hold power.
Many Electric Bike service and repair tasks require special knowledge and tools. Do not begin to perform any adjustments/modifications or services on your Electric Bike if you are not qualified or authorised to perform them. Improper adjustment or service may result in damage to the Electric Bike or an accident which can cause serious injury or death.
Helmets
Always wear a helmet fitted properly, which covers the forehead when riding a bicycle.
Many states require specific safety devices. It's your responsibility to familiarise yourself with the laws of the state where you ride and to comply with all applicable laws, including properly equipping yourself and your bike as the law requires.
Bicycle safety helmet should always be worn while riding your bicycle.
The correct helmet should:
- Be comfortable
- Be lightweight
- Have good ventilation
- Fit correctly
- Cover your forehead

Assembly
Pedal Installation
The pair of pedals will have “R” and “L” markings (picture 1), “R” for right, “L” for left. Tighten the pedals onto the bike by turning them clockwise (R) or anti-clockwise (L). (Picture 2)

Front Wheel
- Make sure that the brakes are loose enough to allow the wheel to pass through the brake pads easily.
- Place wheel into fork dropouts.
- Install retaining washers with the raised lip pointed towards the fork and insert them into the small hole of the fork blade.
- Install the axle nut and tighten it. Make sure the wheel is centred between the fork blades.
- Spin the wheel to make sure that it is centred and clears the brake shoes.
- Tighten the brakes if necessary.
Saddle Position
Correct saddle position is an important factor to get the best performance and comfort from your Electric Bike.
If you find the saddle not positioned comfortably, then there are two adjustments to make it right.
Up and Down Adjustment
Your leg length determines the correct saddle height.
The saddle position is said to be at the correct height, if you can just reach a pedal in the lowest position with one heel when you are seated and if the crank arms are parallel to the seat tube. To check for correct saddle height, perform the following:
- Sit on the saddle and place one heel on a pedal.
- Rotate the crank until the pedal with your heel reaches the lowest position and the crank arm should be parallel to the seat tube. Your leg should be straight and just touching the centre of the pedal. If this is not the case, your saddle height needs to be adjusted.
Saddle Tilt Adjustment
Most people prefer a horizontal saddle, but some riders prefer the saddle nose tilted slightly up or down.
You can adjust the saddle by loosening the saddle quick release and then tilt the saddle to the desired position and re-tighten the saddle quick release.
Tighten it enough so that you cannot move or jiggle the saddle. Very small changes in saddle position can have a substantial effect on performance and comfort. Consequently, whenever you make a change to your saddle position, make an only one-directional change at a time and make the changes in small increments until you find the position you are most comfortable.
How to Fold the Bike
- Turn the key switch to OFF.
- Unlock the handlebar quick-release lever (A, Picture 1) and push down the handlebar to the lowest position, then lock the handlebar quick-release lever.
- Unlock the handlebar quick-release lever (A, Picture 2) and rollover the handlebar.
- Rotate the pedal upward so it is perpendicular to the ground. (A, Picture 3)
- Release the lock lever from its clasp on the right side of the Electric Bike. (A, Picture 4)
- Rotate the lock lever (A, Picture 4) clockwise until it points backward, pull the lock nut and rotate the locknut (A, Picture 4) out from the Electric Bike until the nut clears the lock plate (B, Picture 4).
- Grasp the seat and the handlebar. Pivot the front half of the frame rearward around the hinge until the front wheel is beside the rear wheel.

Operation
Please read and understand these instructions completely before operating your Electric Bike to prevent serious injury to yourself and others and to prevent damage to the bike.
Important notices:
- Always recharge the battery immediately after each use. Failing to do, may damage the battery.
- When stored over 1 month, the battery should be checked and fully recharged before riding.
Riding Method
Be familiar with all the spare parts of the Electric Bike and test all the electric functions before riding. Make sure all the spare parts for the bicycle are in good condition. Check the power of the battery and the pressure for tyres.
Starting Up
Insert the key into power switch at the right side of the battery box, turn to “ON” status, the power display will turn on, meaning the power supply is normal.
- Start-up with Accelerator: Turn the accelerator from outside to inside (anticlockwise) and the rotation angle should be from small to large for starting, then you can adjust the speed by turning the accelerator slowly. The speed can increase to 25km/h; however, actual speeds depend on the weight, the road, tire pressure and other factors.
- Start-up with Pedal Assist: After turning on the power, you can also turn the pedals for one and a half cycles to start-up the Electric Bike, then you can control speed of the bicycle by pedalling, if you pedal faster the speed of the bicycle increases, but do not pedal too hard, it can cause damage to the components of Electric Bike.
Riding Safely
Riding on the road:
- The speed should be increased slowly after start-up, to prevent wasting of energy and damage to electrical components, it is much better to start-up using the pedal assist method.
- Ride using the pedals when climbing inclines, in order to extend the service life of the battery and the motor.
- Try to reduce frequent braking and start-up while riding, in order to save energy.
- To stop the Electric Bike, you can release the accelerator by turning it clockwise, the speed will decrease and stop.
- Do not accelerate and brake together while riding, you can release the accelerator first and then brake. If the motor overloads by accelerating and braking at the same time, it can damage the other components of the Electric Bike.
- The load standard weight is 75kg (including the rider weight), please do not overload with more weight.
- A rear brake system has been installed to the Electric Bike, it will automatically cut off the power supply to the motor and slow down when you pull the brake and then the rear brake in the back tyre stops the Electric Bike.
Parking:
- Shut off the power switch after you get off, in order to prevent accidents by accidentally turning the accelerator and starting up the bicycle abruptly.
- Do not start bicycle frequently while resting, to ensure the service life for the battery, motor and electric switch.
- Shut off the power after parking and remove the key.
Battery charging:
- When the ride is over or the battery is running out, charge the battery immediately.
- Charging can be performed in two ways:
- Remove the battery from the bike and then charge it
- Charge the battery while it is connected to the Electric Bike.
- Attach the charger connector to the bike and the AC connector to a wall outlet.
- There is an LED indicator on the battery charger unit. The LED glows red when the power is connected and the battery is charging.
- When the LED turns green, it means the battery is full.
- For Li-ion battery, the recommended charge time: 5-6 hours.
- Do not charge continuously for more than 18 hours.
- After charging, unplug the input socket first (from the outlet), then unplug the output socket (from the bike).
- The battery charger must provide a constant voltage. A fluctuating voltage or fluctuating power supply may damage the battery storage cells.
Inserting, Unlocking and Removing the Battery
- Insert the key into the keyhole.
- Turn the key switch to ON when using the Electric Bike. (C, picture 5)
- Turn the key switch to OFF after using the Electric Bike. (B, picture 5)
- Turn the key switch to unlock position (A, picture 5), then the battery unlocks and becomes removable.
Picture 5
Power Indicator
When the throttle or sensor is engaged (Powering the motor) and the bicycle is in motion, the LED on the battery gauge (on the throttle or separate unit) indicates instantaneous line voltage as measured at the battery terminals and not the available energy in the battery pack.
The line voltage will wing out on a dead stop or going up a steep hill, the motor will be under a high load and may show a reduced number of LED indications or show the “Yellow” or even “RED” LED.
When the throttle is disengaged (i.e. no power to the motor as the bicycle is stationary or coasting) the LED on the throttle will indicate the voltage of the battery pack. The voltage of the battery pack will rise when no load is on the motor. The best way to know the remaining battery life is to check the throttle LED after reaching cruising speed on a flat straight road, as this will allow the battery voltage to stabilise and give a much more accurate reading.
Pedal Assist System
The bike has an electric pedal-assisted driving system.
The driving assisted system consists of a driving unit, a battery, a controller and various electronic components (harness wires, sensors and switches). It is important to know that when the assistant system is turned on, the driving unit engages to provide power only while you are pedalling.
The amount of power provided by the drive unit depends on your pedalling force and the assistance model/level you set on handlebar control unit at any time, if you stop pedalling, the drive assistant will disengage. In all levels, the driving assisted system power reduces progressively and cuts off as the bike reaches a speed of 25km/h or sooner if you stop pedalling. The drive assist re-engages when speed drops below 25km/h if the pedals are turning.
The Electric Bike is equipped with multi-function display, which has 3 levels of PAS speed and power indicator light on/off.
Keep pressing '-' button to turn off PAS; you can pedal the bike normally. The drive system is not activated.
Holding the '+' button on the meter can get higher PAS speed level. Each level of assist corresponds to a maximum motor speed; at level 3, the motor runs at full power. Overall range decreases at higher power levels.
Throttles
- The throttle is operated by rotating the throttle towards the rider much like a motorcycle.
- They are the inner half of the right handlebar grip.
- The more you twist the throttle, the faster the motor system will propel the bicycle.
Cleaning & Care

Battery Storage
When storing your batteries for a long period of time
- Charge your batteries every 30 days to avoid loss in battery capacity. Batteries will slowly self-discharge when left unused for a long period of time. If the battery cells are allowed to reach a critically low voltage, their life span and capacity will be permanently reduced.
- Always disconnect your charger from the wall outlet and battery before storing the battery.
- Avoid storing your batteries in extreme temperatures, whether it is hot or cold.
- Batteries are to be kept in a cool, dry place. Do not allow batteries to accumulate condensation, as this could cause shorting or corrosion.
- The recommended storage temperature for Li-ion batteries is between 0-25 °C.
- Avoid exposing the battery to extreme heat (40°C or higher) for long periods of time.
Service & Maintenance Schedule
Some service and maintenance should be performed by the owner and require no special tools or knowledge beyond what is presented in this manual.
The following are examples of the type of service you should perform by yourself. All other services, maintenance and repair should be performed in a properly equipped facility by a qualified Electric Bike mechanic using the correct tools and procedures specified by the manufacturer.
Break-in Period
Your Electric Bike will last longer and work better if you break it in before riding it fast. Control cables and wheel spokes might stretch or sear when a new Electric Bike is used for the first time and may require readjustment. Your mechanical safety check will help you identify some things that need to be readjusted.
Before every ride:
- Perform the mechanical safety check-up.
- Clean the Electric Bike after every long or hard ride or if the Electric Bike has been exposed to water or grit or at least every 150km.
- Lightly oil the chain and freewheel cogs. Wipe off excess oil. Lubrication depends on the climate.
After every long or fast ride or after every 10 to 20 hours of riding:
- Squeeze the front brake and rock the Electric Bike forward and back. Does everything feel solid? If you feel a clunk with each forward or backward movement of the Electric Bike, you may have a loose headset or brake.
- Lift the front wheel off the ground and swing it from side. Does it feel smooth? If you feel any binding or roughness in the steering, you may have a tight headset.
- Make sure all bolts, nuts and mounting hardware are tight.
Caution:
Since the right pedal on your Electric Bike folds up, grasp the crank arm when performing this check on the right side.
Warning:
Like any mechanical device, an Electric Bike and its components are subject to wear and stress. Different materials and mechanisms wear at different rates and have different life cycles. If a component's life cycle is exceeded, then the component can suddenly and catastrophically fail, causing serious injury or death to the rider. Scratches, cracks, fraying and discolouration are signs of stress-caused fatigue and indicate that a part is at the end of its useful life and should be replaced.
Flat Tire
If you get a flat tire, remove the wheel. Depress the tire valve to let all the air out of the tube. Remove one bead of the tire from the rim by grasping the tire at a point opposite the valve stem with both hands lifting and peeling one side of the tire off the rim.
If the bead is too tight for you to unseat it with your hands, use tire levers to lift the bead carefully over the tire rim. Push the valve stem through the wheel rim. Remove the inner tube.
Carefully check the outside and inside of the tire for the cause of the puncture and remove the cause if it is still there. If the tire is cut, line the inside of the tire in the area of the cut with something handy - tape, a spare patch, a piece of inner tube, whatever will keep the cut from pinching the inner tube. Either patch the tube (Follow the instructions in your patch kit (sold separately)) or use a new tube.
Reinstall the tire and tube. Slip one tire bead over the rim. Insert the tube valve through its hole in the rim. Feed the tube carefully into the cavity of the tire. Inflate the tube just enough to give it some shape. Starting from the valve stem, please use your thumbs to set the tire bead inside the rim.
Work your way around both sides of the wheel until the entire bead is seated in the rim. Be careful not to pinch the tube between the tire bead and the wheel rim. If you have trouble getting the last few cm of bead over the edge of the rim with thumb pressure, use a tire lever and be careful not to pinch the tube.
Caution:
If you use a screwdriver or any tool other than a tire lever, you are likely to puncture the tube.
Check to make sure that the tire is evenly seated around both sides of the rim and that the tube is inside the tire beads. Push the valve stem into the tire to make sure that its base is seated within the tire's beads. Inflate the tube slowly to the recommended pressure, all the while checking to make sure that the tire beads stay seated in the rim. Replace the valve cap and install the wheel onto the Electric Bike.
Warning:
Riding your Electric Bike with a flat or underinflated tire can damage the tire, tube and Electric Bike, and can cause you to lose control and fall.
Broken Spoke
A wheel with a loose or broken spoke is much weaker than a fully tensioned wheel.
If you break a spoke while riding, you will have to ride much more slowly and carefully because the weakened wheel could break additional spokes.
Warning:
A broken spoke seriously weakens the wheel and may cause it to wobble, striking the brakes or the frame. Riding with a broken spoke can make you lose control and fall.
Twist the broken spoke around the spoke next to it, which prevents flopping around and getting caught between the wheel and the frame. Spin the wheel to see if the rim clears the brake pads.
The wheel will not turn if it is rubbing against a brake pad. Try turning the brake cable by adjusting barrel(s) clockwise to slacken the cable and open the brakes. If the wheel doesn't turn, open the brake's quick release and secure any loose as best as you can. Walk with the Electric Bike or you must ride it with extreme caution because will have only one working brake.
Basic Maintenance
Properly maintain the batteries by keeping them fully charged when not in use.
Do not ride your electric bicycle in the water (damp roads, puddles, rain, streams, etc.) and never immerse it in water as the electrical system may be damaged.
Check the wiring and connectors periodically to ensure there is no damage and the connectors have good continuity.
Store your bicycle under the shelter. Avoid leaving it in the rain or being exposed to corrosive materials.
Riding on the beach or in coastal areas exposes your bicycle to salt which is very corrosive. Wash your bicycle frequently and wipe or spray all unpainted parts with an anti-rust treatment. Make sure wheel rims are dry so braking performance is not affected. After rain, dry your bicycle and apply anti-rust treatment.
If the hub and bottom bracket bearings of your bicycle get submerged in water, they should be taken out and re-greased. This will prevent accelerated bearing deterioration.
If paint gets scratched or chipped to the metal, use touch up paint to prevent rust. Clear nail polish can also be used as a preventative measure.
Regularly clean and lubricate all moving parts, tighten components and adjust as required.
Storage
Keep your bicycle in a dry location away from the rain and sun.
Direct sunlight may cause the paint to fade or rubber and plastic parts to crack. Before storing your bicycle for a long period of time, clean and lubricate all components and wax the frame.
Deflate the tires to half pressure and hang the bicycle off the ground. Charge your batteries and make sure they are protected from water.
Batteries should be charged every 30 days to avoid loss in battery capacity. Don't cover the bicycle with plastic as “sweating” may cause rusting.

Q: Is it normal that the batteries get warm when recharging?
A: Yes, it is normal that the batteries will become warm to the touch during the recharging process. This is because of the increase of internal resistance and less energy conversion efficiency from electric energy to chemical energy.
Q: How long will my batteries last before needing replacement?
A: Average battery life depends on use and conditions. Even with proper care, rechargeable batteries do not last forever. Li-ion batteries will typically last more than 800 cycles. A partial charge/discharge counts fractionally against those numbers; running the battery down halfway then recharging it completely uses up one half of a charge cycle.
“End of useful life” refers to the point at which a battery can no longer supply 60% of its original rated capacity in ampere-hours. After this point, the ageing process will accelerate, and the battery will need to be replaced.
