Tighten the screws to hold the bar in place, ensuring all brake cables is clear, the suggested torque is 13-14N.mThe stem must be inserted to the Minimum depth or lower as indicated on the steer post to insure the safety, see the picture. Tighten the stem screw located on the top of the handlebar stem.

• You may adjust the handlebar stem angle by loosening the Allen key screw located underneath the stem. Tighten the stem, and adjust the screw securely after positioning the stem angle. The tightening torque between the handlebar and the frame stem should be bigger than 18-20N.m
• Check that the forks and the handlebars are facing forward and straight. Stand at the front of the handlebar, vise the front wheel by your legs, and hold the handlebar, adjust the handlebars and the body of the bicycle to form an angle of 90 degrees, see the picture.

Some models have a light/power meter console that attaches to the handlebar. Attach this with the plastic brackets and screws provided.

The adjustment of the wheel:
After loose the wheel, please adjust it according to the recommended torque. The fasten torque should be no less than 30Nm for the rear wheel. The fasten torque of the front wheel should be no less than 25 N.m

Check and adjust the DISC BRAKES
Left for rear brake, right for front brake.

1. Check the tightness of the six disc mounting bolts holding the brake rotor onto the wheel. If you need to remove these bolts, be sure to us a thread-locking compound when re-installing them.
2. Make sure the two bolts securing the caliper adaptor bracket to the fork are tight.
3. Thread the brake cable through the caliper as shown and secure it with the cable fixing bolt.
4. Loosen the two caliper mounting bolts enough to allow the brake caliper to float freely.

Adjust the Saddle

• Your seat will tip forward for easy battery removal on most models.
• Your seat height is adjusted by a quick release. Pull the quick-release lever, Insert your seat post to at least the minimum insertion line marked on the post. Tighten the adjusting nut by quick release lever, then push the quick release lever to the closed position, the suggested torque is no less than 19.5N.m.
• The seat angle is adjusted with the nuts that attach the seat to the seat rail. Ensure that the nuts are tightened firmly and that the seat does not move forward or back while you are sitting on it.

Adjustment of the seat post
The adjustment method is as follows
Lose the hand release of the seat post, take out the seat post; Adjust the screw, Take the seat post back the frame tube as a former station, and tighten the clamp of the seat position.

Attach the Pedals

Pedals are marked „L‟ and „R‟ on the axle end, Screw the pedal marked „L‟ into the left side of the crank and „R‟ to the right.

1. The right pedal attaches to the chain side crank arm with (clockwise) thread
2. The left pedal attaches to the other arm and has a left-hand (counterclockwise) thread.

Check your pedals before each ride to ensure that they are tight. If you ride your bike with loose pedals, you may strip the threads that hold the pedal to the crank.

Operation of Your Electric Bike
Your e-bike is driven by a motor embedded in the hub of the rear wheel and can not be driven directly by throttle. The motor is powered by a battery. The amount of power delivered to the motor, and hence the accelerating force on the e-bike, is controlled by you in a way according to the power-assisted mode you choose.

Electric -Assisted:

• You must turn on the battery to use the e-bike in Electric-Assisted mode.
• In the Electric-Assisted model, power assist is triggered when you pedal forward, and power assist stops when you stop pedaling. In other words, power assist happens as long as you pedal. You don’t need to pedal hard. All you need is to apply a light force to the pedals continuously to maintain the current flow. When you apply one of the brakes, the power-assist will automatically stop. allowing the e-bike to slow down and stop. Power assist will turn itself off when the e-bike has reached the maximum speed of 25km/h.
• You should use the SHIMANO gear shifter at the handlebar to set the gears appropriately according to road conditions and pedal as usual, you will find that you need to exert a lot less effort and the e-bike travels faster and at a more steady speed.
• Note that the Battery level indicators on the handlebar will show the correct level only when power is not being drawn from the battery.

Charging Your Battery

• Fully charge your battery before your first ride and then after any operation, especially after long-distance riding
• Your charger plugs directly to your battery pack with either a round (RCA or XLR) connector or the same 3-prong plug as your bike’s power cord.
• You must plug your charger to the bike first and then to the wall outlet.

NEVER PLUG A POWER CORD FROM A WALL OUTLET DIRECTLY INTO THE BATTERY!YOU MUST USE YOUR CHARGER!

• The light on the charger will be red while charging and turn green when finished. When the charger‟s light turns green, please keep on charging the battery for 1-2 hours to ensure that the battery has a longer usage life. Then unplug your charger from the battery and the wall.
• Always charge your battery before it gets too low. If you let your pack run completely dead, it may not recharge. It is a good idea to turn the key to the position OFF and remove your key after any ride so that it will not be left on accidentally.
• Your lithium battery pack switch has three positions. To the left is “off”. Turn the key to the right to turn the bike on.
• To unlock the pack, push the key in slightly and turn to the left. It can then be removed. Push in and turn right to lock it on.
• The red button on top of the pack shows the power level when pushed. The first light only comes on when the battery is too low to run the bike. The next lights indicate low, medium, and full. The lights on the handlebar also show the level.
• Remember: the sooner you charge after riding the longer your pack will last.
• The Lithium battery is built with circuitry that prohibits over-charging and excessive discharging.
• The battery charger is designed specifically for the bike; connecting the battery to any other charger will void the warranty

Operation of Your Display

• This LCD can show the speed, battery power, ODO, and 1-5 levels PAS ASSIST
• The bike speed is around 6km/h to 25km/h in the 5 levels.Press the “M” to switch on the power of LCD, and press “+” PAS grade +1. Press “-” PAS grade-1 .

Derailleur The gears or derailleur should only be shifted as you pedal to keep the derailleur in adjustment.The derailleur/shifting and pedaling are completely independent of the motor.

Best Practices

• Please observe the traffic regulations.
• Keep both your hands on the handlebars ready to brake while riding.
• Always charge your battery after riding.
• Don’t run your battery dead or extremely low. If you do, charge as soon as you can. Remember to turn off the key when you stop.
• Always remove the key when you are riding. If left on, the battery will slowly drain.
• Running distance per charge of King Sports E-bike
• Under standard road conditions (concrete and cement road without wind resistance and with temperature around 25°C, the battery capacity attenuation≤5% ), the running distance per charge is up to at least 30 Km.
