Read This First: Safety and Compliance withtheLaw

Congratulations on your purchasing of your new e-bike. Your newe-bike is anexcellentpiece of personal transportation equipment that will give you good service for manyyears. Before you start using your e-bike, we want you to be aware of a fewimportant points. Please read this section carefully..

• Observe Laws Regarding the Use of Battery-Operated Bicycles
  Your e-bike is designed and manufactured to meet safety requirements as abattery-operated bicycle. However, state and local laws governing the use of battery-operated bicycles on public roadways, parks, and other open areas maydiffer.Please check with your local authority before using your e-bike in public areas.

• Observe Laws Regarding the Use of Bicycles
  Note that all laws regarding the use of bicycles in public areas, such as thosemandating the use of helmets and the use of infant seats, will automaticallyapplyfore-bikes. Check with your local authority on what restrictions might apply-

• The Lithium-ion Battery of Your e-Bike
  Your e-bike is equipped with the latest battery technology. The lithium- ionbatteryismuch lighter than lead- or nickel-based batteries that are being used in someoldermodels.

• Your First Ride
  Please be VERY CAREFUL when you are ready to get on your e-bike for thefirsttime because that the e-bike moves significantly faster than a regular bicycleat activepower-assisted mode. Take your e-bike to an area with a lot of open space beforeyoustart. Do not start pedaling hard as soon as you get on the e-bike (as younormallywould be with a regular bicycle), as the e-bike will accelerate under pedal-assist mode and you may be unprepared for the sudden increase in speed. However, afterafew times, you will enjoy using the pedal- assisted function.

Assembling Your New e-Bike

If you purchased your e-bike unassembled, please follow these instructions toassemble your e-bike under the guidance of an adult or a qualified technician. Assemblyis quite easy as most of the parts are already assembled; you need only to put afewlargepieces together to complete the job. For more information,please contact the shop where you intend to buy

• Name of each Part
  

• Check that the Package is Complete and Undamaged

Your e-bike comes in a carton containing the following:

• * The main body of the e-bike – consisting of the frame, the rear wheel, thegear and chain, the rear brake, the battery in the frame, the rear fender.

  • The handlebar subassembly with the battery’s keys that attachedonit-the handlebar subassembly is not really separate, as it is connectedtothemain body by the brake cables and electrical wires.
    The handlebar alsohas the brake levers and gear control already assembled. Additionally, the right handle also has an integrated control for the throttle modepower assisted, a display panel.

  • The Seat – the seat is attached to its pedestal stem. The front wheel

  • The front wheel fender with supports

  • Front light -the front light is not really separate, as it is connectedtothemain body by an electrical wire. ◊ Tools and other parts -One multi-tools, one charger, a pair of foot pedalsand this manual, they are contained in a separate box.

• Assembly – Step 1: Attach the handlebar subassembly

Stand the main body of the e-bike on the kickstand. Stand up and lock the steeringcolumn that is at the front of the main body frame, insert the stemof the handlebarsubassembly into it. Make sure that the fork (that will hold the front wheel) is pointingforward, and orient the handlebar accordingly. Insert the stemall the way andtightenfrom the top using the quick lock.

• Assembly – Step 2: Attach the Front Wheel Fender and the Front Light

Make sure that the fork from the steering column is pointing forward. Place thefront lightand the front fender within the fork: locate the small projection with a screwholeat thetop of the fender, fit it to the bolt at the back of the base of the steering column; attachthesupports (one on each side) to the base of the fork using two small bolts (supplied). Afterall three points (the dorsal point and the 2 support points) are properly attached, usethemulti-tools to tighten.

Fix dorsal point to base of steering column

• Assembly – Step 3: Attach the Front Wheel and Adjusting the Front Brake

Make sure that the fork from the steering column is pointing forward. Removetheprotective bar from the front fork, place the front wheel within the fork andthebrakediscwithin the brake block, seat the axial stem properly within the receptacles at thetipsofthe fork, and tighten the nuts with the multi-tools. Make sure that the front wheel movesfreely and does not wobble from side to side. Reposition the wheel and re-tightenifnecessary.

Test the brake by lifting the front of the e-bike and setting the wheel in motion(turnit)and apply the brake at the handlebar to stop it. If you could not set the wheel infreemotion, or if you could not stop it by applying the brake, you need to re-adjust byincreasing or decreasing the clearance. Caution: Do not operate the e-bike until you are satisfied that both the front andrearbrakes are operational.

• Assembly – Step 4: Installing the Seat and Pedals

Insert the pedestal stem of the seat into the seat column of the main body frame, usethebuilt-in lever to tighten. Attach a pedal on each side of the crank, tighten with the multi-tools. Inflate the tires to proper pressure. At this point, your e-bike is a completely functional bicycle, although without anybatteryoperated to function as yet. Check all tightening points to make sure. Take a short ride.Adjust the height of the handlebar, and the height and the tilt of the seat, if necessary, formaximum comfort.

• Assembly – Step 5: Charging the Battery

plesae note：
Remove the charger from the box, the first step is Insert the plug at the endof thesmallercable into the charging terminal of the battery，and attached the power cord,withtheaothe side insert that to any wall outlet and start charging. The charging terminal isontheside of the battery opposite to a hole on the side of the frame. The LEDonthechargerglows RED while charging and glows GREEN when charging is complete. Thebatteryshould be turned OFF while being charged. When the LED on the charger turnsGreen,disconnect the charging cord and cover the charging terminal with the rubber cap. If a battery is installed on the e-bike and turned ON, the display panel will showthecharge level of the battery when the bike turned ON. You are now ready to start using your e-bike.

Operating Your New e-Bike

The method to turn on the bike is: I, twist the battery lock counterclockwise to theendtoturnon the battery; II, press power button on the left handle bar until the display lights on; III,ride on the bike and twist the throttle bar or pedal the bike, the bike will move, youcanchange the power level with control buttons, level 1 is the slowest and level 5is thefastest,level 0 is human model. Your e-bike is driven by a motor embedded in the hub of the rear wheel. The motor ispowered by a battery. The amount of power delivered to the motor, and hence theaccelerating force on the e-bike, is controlled by you in a way according to the power-assisted mode or full power mode you choose. You can configure the e-bike to operate in the pedal-assist-only-mode or the full powermode (should check against local laws to ensure full power mode is permitted) whereyoucan also use the hand throttle to deliver power to the motor. •

• Your First Ride
  (Reprinted from the Safety and Compliance with the Law section)
  Please be VERY CAREFUL when you are ready to get on your e-bike for thefirst timebecause the e-bike moves significantly faster than a regular bicycle at activepower-assisted mode. Take your e-bike to an area with a lot of open space beforeyoustart. Do not start pedaling hard as soon as you get on the e-bike (as you normallywoulddo with a regular bicycle), as the e-bike will accelerate under pedalassist modeandyoumay be unprepared for the sudden increase in speed. However, after a fewtimes, youwill enjoy using the pedal- assisted function.

• Pedal-Assisted
  You must turn on the battery to use the e-bike in pedal-assisted mode. In the pedal-assisted mode, power assist is triggered when you pedal forward, andpowerassist stops when you stop pedaling, sometime would be delay. In other words, powerassist happens as long as you pedal. You don’t need to pedal hard. All youneedistoapply a light force to the pedals continuously to maintain the current flow. Whenyouapply one of the brakes, power assist will automatically stop, allowing the e-biketoslowdown and stop. Power assist will turn itself off when the e-bike has reachedthemaximum speed that the power level you choose. You should use the gear shifter at the handlebar to set the gears appropriatelyaccordingto road conditions and pedal, as usual, you will find that you need to exert a lot lesseffortand the e-bike travels faster and at a more steady speed.

• Hand Throttle Control
  In the hand throttle mode, amount of power assist is determined by the throttleswitchcontrolled by your hand. You control the throttle by twisting it fromits restingposition,the farther the throttle switch is from its resting position, the more power is deliveredtothe motor to accelerate the e-bike. When you want to slow down, you simplyreleasethethrottle and let it return to its resting position, and simultaneously apply the brakesifnecessary. You do not need to pedal the e-bike if you use the hand throttle. However, youcanpedalwhile commanding power assist. If you do pedal to help the movement, youconserveenergy and the charge in the battery will last longer.

• Charging Your e-Bike Battery
  Your e-bike battery is a lithium-ion battery. Lithium-ion battery requires speciallydesigned chargers. You should never charge your battery with a substitute charger thatisnot designed for this use. Use of an unsuitable charger to charge a lithium-ionbatterywillresult in overheating, fire or even explosion. If your charger is lost or damaged, contactyour dealer to order a replacement. Charge your battery while the e-bike is not in use. You should turn off the batterybeforeyou charge it. You may charge your battery while it is mounted on the e- bike, or afterithas been removed from the e-bike. Do not place either the charger or the battery near flammable substances whilechargingis taking place. Charging should not be done in the vicinity of infants and small children.It is also prudent to remove valuable objects from the immediate vicinity of thebatterywhile it is being charged. The length of charging time depends on the level of charge the battery still holds. Ifabattery is completely discharged, it will take 6 hours to be fully recharged. Whenabattery is fully charged, the LED on the charger will transition fromREDtoGREEN. Atthis point, you should disconnect the charger. Do not leave the charger connectedtothebattery for a very long period of time after charging is complete. (Leavingit connectedfor an overnight charging is OK. It is normal for the charger and the battery to be slightly hot while chargingis ongoing.• Removing the Battery from the e-Bike
  The battery is an important and costly part of the e-bike. It is designed to be lockedintoposition with a key to preventing theft. You can take further precaution byremovingthebattery while the e-bike is parked unattended. You may also have a need toremovethebattery from the e-bike to recharge it at a location where you cannot park your e-bike.The method to remove the battery is: I, open the cap of the charging port andfoldthebike; II, insert the key into the battery, hold pressing the key a bit until twist Counterclockwise to the end (Note: You can’t remove the battery until the lockbarwithdraws into the battery completely); III, slip off the battery, the battery is quiteheavyand you should take care not to drop it.

• Maximizing the Riding Range
  Many factors affect the rate of use of the electrical energy and the riding range.

  • You should fully charge the battery before a long journey.
  • Rough road conditions and hilly terrain will consume more energy.
  • Frequent change of speed will consume more energy.
  • Carrying more weight on the e-bike will consume more energy. ◊ Keeping the tires properly inflated and keeping the e-bike clean andwell lubricated will save energy.
  • Making sure that both wheels move freely when brakes are not appliedwillsave energy. You should check brake adjustments frequently.
  • Pedaling as you ride will consume less electrical energy and increasetheridingrange.
  • When the battery is turned off, your e-bike functions as a regular bicycle. Ifyouembark on a very long journey, you might want to turn off the batteryforlongstretches where the road is level or downhill and pedal the e-bike as aregularbicycle so that you can conserve electrical energy stored in the battery

Care and Maintenance for Your Newe-Bike

You should, in general, take care of your e-bike the way you would witha regularbicycle by keeping it dry, clean and the moving parts well lubricated. You shouldalsoavoidparking your e-bike in exposed areas whenever possible. You should check the effectiveness of the brakes before each use.

• For your e-Bike, you should also take note of the following:
  • Your e-bike is designed for regular country road use for a single person. Usingyour e-bike for extreme maneuvers, such as extreme off-road use, jumping, orcarrying the excessive load will damage the e-bike and could causeseriousinjury.
  • Do not use high-pressure water streams to clean your e-bike, as water mightseep inside the motor or the wiring compartment and cause rustingof electricalparts or short circuits.
  • Avoid parking your e-bike outside when there is rain or snow. At theendofatrip where there was rain or snow, bring the e-bike inside and use aclean, drytowel to eliminate any wetness.
  • Be sure you do not lose both keys. If you lost one key, you shouldimmediatelymake a copy as a back-up. If you lost both keys, you will be unabletoremovethe battery from the e-bike.
• Special Care for the Battery and the Charger
  • Use only the supplied charger to charge your battery. Do not use anunauthorized substitute. If your charger is lost or damaged, contact your dealerto order a replacement
  • Do not open or alter the battery or the battery charger.
  • Do not place the battery near fire or corrosive substances. Do not immerseinwater or other liquids.
  • Avoid subjecting the battery from high temperatures, such as directlyunderthehot sun, for prolonged periods of time.
  • Do not connect (short circuit) the two poles of the battery.
  • After much use, your battery’s charge holding capacity will decrease. If youfind that your battery does not hold sufficient charge even for short trips, youshould contact your dealer to order a replacement. Under normal use, thebattery will undergo 500 charging and discharging cycles.
  • If the battery will not be used for an extended period of time, chargeit fullyandrecharge it every 3 months. Store it in a cool place.
  • Your e-bike battery is engineered with precision for highcapacityandlong useful life. We do not recommend that you use it to power otherelectrical devices. Improper use of the battery will damage the batteryandshorten its useful life and may cause a fire or an explosion.
