Product Overview

Assembly

Front wheel

1. There are two springs, a lever and a nut on the quick release skewer. Remove the nut and one spring. Remember that don’t unscrew any nuts on the hub of the front wheel

2. Get the front wheel and insert the skewer from the disc side.
   From the other side, attach the spring followed by the nut.

3. The larger sides of the springs are on the outside end of the skewer.
   

4. Lift the bike, then insert the disc brake into the caliper. Make sure that the axle fits nicely in the front forks.

5. Tighten the nut on the skewer until the lever becomes firm to close. The lever should leave an imprint in your palm.

Headlight

1. Make sure the front fork brace is at the front of the bike, not at the back.
2. Place the headlight and the fender at a right position, then tighten the screw. The headlight can be adjusted up and down to change the illumination angle.

Handlebar

1. Turn the stem to the front

2. Remove the faceplate of the stem.

3. Take care to note that the cables should run cleanly from the handlebar. They should not be twisted. Don’t remove or detach the cables

4. Insert the handlebar then reattach the faceplate of the stem.
   

5. Tighten the screws. You should keep swapping between the screws to ensure that the faceplate has a consistent gap from the stem along all edges and tighten securely. The handlebar should be aligned so that the once front wheel is installed, the brake
   levers are at 45 degrees to the ground.

6. Tighten the screw under the black rubber cover where on the top of the fork.

7. Align the stem with the front wheel. Tighten the two screws on the stem.

Pedals

1. It is important to note that pedals are sided. Remember this is always from the perspective of the rider. Locate the left hand side/ right hand side pedal, which is marked “L” and “R”
2. The thread on the left hand pedal is reversed. So tighten it counter-clockwise. Install the left hand pedal into the left crank arm gently by hand. Then tighten the pedal by a 15mm wrench
3. The right hand pedal has a normal thread. So tighten it clockwise. Install the right hand pedal into the right crank arm gently by hand. Then tighten the pedal by a 15mm wrench.

Seat post
For better pedaling, safety and overall riding comfort, positioning the seat at the right height is important. The rider’s leg length is used to determine the seat’s position. When you pedal, your hips should remain level and your legs should be almost fully extended at the boom of the pedal stroke, but not over-extended
To determine the right seat height, sit on the eBike with one pedal at its lowest point and place the ball of your foot on the pedal.
Your leg should be almost fully extended with a slight bend at the knee

1. Open the quick release lever. Insert the seat post into the seat tube.
2. Adjust the height of the seat. Do not raise the seatpost beyond the minimum insertion marking on the seat post.
3. Tighten the nut on the quick release until the lever becomes firm to close. Close the quick release lever by your palm or finger.

Adjusting the Seat Position and Angle
To change the angle and horizontal position of the seat:

1. Use a 6 mm Allen wrench to loosen the seat adjustment bolt on the clamp positioned underneath the seat, above the rear wheel. Do not remove the bolt fully.

2. Move the seat backward or forward to adjust the angle. A seat position horizontal to at ground is desirable for most riders.

3. While holding the seat in the desired position, use a 6 mm allen wrench to tighten the seat angle adjustment bolt securely to the recommended torque value.

Recommended Torque Values

It is recommended that fasteners be tightened to the manufacturer’s specification found below:

Preparing to Ride

Ensure all components are properly secured before riding other wise serious harm or death could occur.All components should be torqued to the torque specified in the Recommended Torque Values section of this manual.Refer to the table of contents at the  beginning of this manual for the page number of this section. This includes but is not limited to:pedals, handlebars, handlebar clamp, cranks, seat,and seatpost clamp.
Make sure you can’t twist the seat or stem out of alignment by hand.
Check to see if your saddle is positioned at the proper height.Sit on the saddle facing forward and place the ball of your foot on the pedal at its lowest point. Your leg should be mostly straight at this point with a slight bend at the knee. You should be able to pedal  the bike without overextending your leg when the pedal is at its lowest point. Your legs may be overextended if it causes your hips to move side to side, which means the seat must be lowered.
Check that your suspension fork is properly adjusted for the terrain and your weight. The suspension fork will affect the handling of the bike, primarily when going over bumps and stopping. In some situations, it may be advantageous to lock out the suspension  so it is fully rigid.
The suspension fork can be locked out so it is rigid, and the tension is adjustable. To adjust the suspension fork use the knob. To fully lock the suspension, turn the knob clockwise towards the “lock” direction indicated until it cannot be turned further.
To increase the stiffness. turn the knob clockwise towards the “lock” direction indicated. To make the suspension softer, turn the knob counterclockwise towards the “open”direction indicated.

Operate Your E-bike

Make sure you read this entire manual before turning on and operating your eBike.
Now that your eBike is installed. It is almost time to start riding.
The EXRBYKO bikes are equipped with pedal assist, a twist throttle, and can also be used as a regular bike.
Before learning about how to operate your new eBike, it is important you know where all of the important controls are located. Below are photos showing where key controls and features are on your eBike.

Operating the LCD Display

Press the power button
Enter walk mode| Hold the down button
Enter cruise speed| Press and hold the throttle while holding the down button

Notes: The trip meter will reset when the bike is powered off.
The maximum and average speed will be calculated for a given trip, and will reset when the bike is powered off. When the bike has not been used for 10 consecutive minutes, the display will automatically shut down.The pedal assist and throttle features will no  longer work when the display is turned off.

Walk Mode
In general, electric bikes are heavier than the non-electric counterparts. This makes walking the bike a more strenuous activity. To make walking the bike easier,EXRBYKO bikes are equipped with walk mode. If you hold down the down button on the display  control pad, the motor will engage at a speed similar to a slow walk. When walk mode is engaged, a “Walk” indicator will appear on the display. To deactivate walk mode, simply pull the brake levers to engage the motor inhibitors or press and hold the down  button.

Cruise Control
Cruise control on EXRBYKO bikes work similarly to cruise control on a car. To activate: hold the down button while pressing and holding the throttle. The bike will try to maintain a speed based on the position of the throttle
when cruise control was activated. For example, if the throttle is held all the way from its resting position (to a position that would normally maintain 20km/h) and the down button is held, cruise control will be activated and set at 20km/h. Even if the bike is  currently going slower than 20mph, the bike will try to accelerate and maintain that speed because it was set based on that throttle position. To cruise at low speeds, only slightly press the throttle and hold the down button. Cruise control can be deactivated at  any time by pulling the brakes or pressing the throttle again, or holding the down button. This will also cut power to the motor as it would during normal operation.

Display Settings
To change display settings, hold the up and down button simultaneously to enter into the advanced settings menu. In this menu, clicking the power button will toggle between each numbered setting. To adjust the value of each setting, click the up and down  buttons accordingly.

Changing the Top Speed
You must check your local laws and regulations to determine if it is lawful to ride this bike on public roads before adjusting the bike’s top speed. Laws vary by trail, path, and road so be sure to check in each new location you will be riding.
To change the top speed of the bike:

1. Access the settings menu by pressing and holding the up and down buttons of the display simultaneously until the screen says “PO1″.
2. From here you can cycle through settings by hitting the power button of the display and adjust the settings by pressing the up or down buttons.
3. Please go to setting“P08″ and change this setting from 100 to 25 (Suppose you want to adjust the maximum speed to no more than 25km h).
4. Press and hold the up and down buttons on the control pad until the main screen is shown once again.
5. Power the bike off by holding the power button to save the settings you have just changed.

Battery Capacity Display
On the top of the LCD display. a battery indicator bar can be found which is labeled “energy bar” .This battery indicator shows the estimated charge left in the bike’s battery. As the battery depletes, tick marks will begin to disappear according to approximately  how much charge in the battery has been used.
The various charge level indicator states are shown below. The battery display will flash when there is no charge remaining.

Note: The energy bar will not always be accurate. The energy bar updates every few minutes based on the current voltage of the battery.

TIPS WHEN RIDING TO INCREASE RANGE
To get the maximum range out of your bike there are some simple things you can do:

• Ride in a lower level of pedal assist
• Use lower assist levels and pedal when climbing hills
• Pedal when starting from a standstill
• Set your max speed lower than 25 km/h on the LCD display

The range the bike can go on a single battery charge can vary significantly between riders, terrain, wind conditions, user input, and additional payload weight.

If you attach a seat for children to the bike,  they must also be wearing a properly fitted helmet at all times.

Pre-ride Safety Check and Inspection
Before each ride, make sure to inspect your eBike to ensure there are no loose fasteners or accessories. Make sure to specifically check that both the front and rear axles are secure.
Also, make sure both the handlebar and the handlebar stem are not loose.Check the tire pressure of both wheels before riding to ensure the tires are inflated to the recommended pressure

Riding in Wet Conditions
This electric bicycle can withstand light rain and small splashes, but is not designed to be subjected to inclement weather, extremely heavy showers, or submersion in water.
Use caution when riding in wet conditions as it will take longer to use the brakes to slow down, and also when turning as the tires may slip. The electrical components on the bike are not waterproof. The entire bike has an IP rating of 67. Water damage is not  covered under warranty.

Riding at Night
Riding at night comes with more risks than riding during the day due to decreased visibility so riders are encouraged to exercise increased caution. Before riding at night, make sure that reflectors are installed on your eBike. For increased visibility, also ensure  the front headlight and rear tail light are turned on and adjusted such that other people on the road can see them clearly. Riders should wear bright colored clothing at night.

Max Weight
The bike can safely carry a total weight of 150 kg. if the rear rack is attached to the bike, the max weight it can hold is 30 kg.
Therefore if you have a payload that is 30 kg the maximum rider weight is120kg. Failure to adhere to these weight limits may invalidate your warranty, cause damage to the bike or rack, or cause serious injury to the rider. Note range and top speed will be  affected by total weight being carried by the bike. If you are over 120 kg you should lock out the suspension fork before riding.
