Assembly 1
Assembly 2
Visit https://www.youtube.com/watch?v=CZBbdOkz_Pw&t=93s for additional help with
assembly, including a step-by-step video walk-through.
If you do not feel comfortable assembling the bike yourself we recommend taking your new bike to a bike shop for
assembly and inspection. If you are willing to assemble the bike yourself be sure to follow all instructions, properly
adjust gears and brakes, and set tire pressure.
1. Be careful not to position your fingers between the latch
and the frame. Doing so may result in injury.
2. Unfold the rear wheel/ section and hold your e-bike
upright with the kickstand. Push the latch closed so that it's
parallel with the bike's frame then turn the latch lock down
towards the latch to lock it in place.
3. Open the kick stand and place the entire bike.
1. Take out the stem and insert it
into the front frame.
4. Fold the headtube
perpendicularto the ground.
2. Adjust the handlebar to
perpendicular to the tire.
3. Push the button on the latch so
that release it and unlock the
folding mechanism.
5. Tighten the screws to fix
the headtube.
6. After the adjustment, fold the
tube back and lock the latch.

Assembly 3
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 bottom of the pedal stroke, but not over-extended.
To determine the right seat height, sit on the E-bike with one pedal at its lowest point and place the ball of your foot on the
pedal. Your leg should be almost fully extended(not lockedout) with a slight bend at the knee.
Assembly 4
（
1）
NOTICE: Ensure the seatpost and seat are
properly adjusted before riding. DO NOT raise
the seatpost beyond the minimum inserbon
marking etched into the seatpost tube (as
shown at right). If the seatpost projects from
the frame beyond these markings (shown far
right), the seatpost or frame may break, which
could cause a rider to lose control and fall.
Ensure the minimum inserbon markings on the
seatpost are inside the seat tube of the frame.
Open the quick release lever by swinging the
lever open and outward fully.
Move the seat up and down by sliding the seatpost in
or out of the seat tube. DO NOT raise the seatpost
beyond the minimum insertion marking etched into
the seatpost tube.
Adujst the seat and the head ofthe seat is
parallel with the top tube. After that close
the quick release lever using your palm or
finger.
(2) Before using the bike, always check to ensure all latches, levers, and quick releases are
properly secured and undamaged. Check that they are correctly secured before every
ride and after every time the bike is left unsupervised, even for a short time. Otherwise,
the handlebar stem and/or seatpost may come loose and can result in loss of control,
damage to the bike, property, serious injury, and/or death.

Assembly 5
Adjusting the Suspension Fork
The suspension fork can move up and down up to 80mm to
cushion bumps in the riding surface, which can make riding on
a rough road or trail smoother and more comfortable.
Depending on a rider's preference, the suspension fork can be
locked out as a rigid fork, which will typically yield higher
efficiency while pedaling.
The lockout lever (1), located on top of the right side of the
suspension fork, can be turned counterclockwise until it stops
to completely lock out the suspension fork's travel. To unlock
the lockout lever, turn the knob clockwise until it stops. When
the lockout lever is unlocked, resistance can be adjusted by
turning.
The preload adjustment knob (2), located on the top of the left side of the suspension fork. To
soften the ride, subtract resistance by turning the preload adjustment knob
counterclockwise, in the direction of the small on the knob. To make the suspension stiffer
when going over bumps, add resistance by turning the preload adjustment knob clockwise,
in the direction of the small on the knob.
Note: If the pedal/ chain doesn't run smoothly or something seems misaligned, please contact Rundeer
Support.
Assembly 6
Thread the right pedal onto the right crank gently by hand,
turning clockwise. Then tighten pedal by alien wrench.
Locate the right-side/ left side pedal, which is
marked "R ： "L/should have an Wsticker
attached.
Thread the left pedal onto the left crank gently by
hand, turning counter-clockwise. Then tighten pedal
by alien wrench.
Check the chain alignment. Rotate the right pedal and
crank toward the back of the bike as though pedaling
backward. Watch the chain and ensure the chain runs
through the drivetrain (the rear cog, chain tensioner; and
around the front chainring) smoothly.

Battery Key Positions
Start-up procedure
Familiarize yourself with the key port and key positions before riding the bike. The photo below
shows the key port aligned in key position 1, in line with the ON icon. In key position 1, the battery is
in the "on" position, with the battery locked to the frame, and the key can't be removed.
• If the battery is in key position 2, (OFF,unlocked to the frame) no buttons or controls can be activated, the bike will
remain off, and the battery can be removed.
NOTICE: You have to press the key then you can switch to unlock position After the bike has
been properly assembled according to the assembly video, all components are secured correctly, a certified,
reputable mechanic has checked the assembly, and you have read this entire manual, turn on the bike and
select a pedal assist level following the steps below:
1. Test the battery lock security. Ensure the key port is aligned with the OFF icon, which indicating the
battery is off and locked onto the frame mount. Carefully use both hands to pull up on the battery to test
that the lock is secure.
2. Ensure proper handlebar and seat adjustment. Note that lowering the seat so the rider can put one or
both feet flat on the ground without dismounting from the seat may offer a safer and more comfortable
Introduction to operating the bike. Ensure the handlebar faceplate bolts and seatpost quick release are fully
and properly secured.
3. Turn the bike on. Insert the key and turn clockwise to the ON positon. Locate the LCD Display (near
the left handlebar grip). Hold down the center M power button for approximately 2 seconds until power is
delivered to the LCD Display.
4. Turn on the headlight and taillight if needed or desired. Once the LCD Display is on, long press
buttons to turn on the lights,
5. Select the desired level of pedal assistance (PAS) between level 0 through 5 using the + and - on the
display remote. Level 1 corresponds to the lowest level of pedal assistance, and level 5 corresponds to the
highest level of pedal assistance. Level 0 indicates pedal assistance is inactive. Start in PAS level Oor 1 and
adjust from there.
6. Begin riding carefully. With the proper safety gear and rider knowledge, you may now operate your
bike. On a flat surface, in a low gear (1 or 2), most riders should be able to begin pedaling the bike with
pedal assist level 0 or 1. You may also use the throttle to accelerate and maintain your desired speed.
7. The throttle is used by slowly and carefully rotating the throttle backward toward the rider. Do not use
the throttle unless you are on the bike.
NOTICE:
Do not use the throttle while dismounted. Avoid accidental application of the throttle while
dismounted; anytime you are moving the bike while dismounted^ ensure the bike is powered
off to prevent accidental application of the throttle.
