NAKTO Discovery User manual

Discovery

Let’s start assembling your NAKTO Discovery ebike!
(Please read this entire assembly manual before assembly as it will save
you a lot of time!)
Step One: Unpack the ebike.
1.Pull the frame and all parts (charger, seat, toolkit, keys & fuse, nut caps,
manual and pedals) out of cardboard box. Separate bike from foam
padding. Cut off all zip ties with scissors while being extra careful as not
to damage the paint or cut any wires or cables.Notice: Keep the spare
fuse in a safe place. It is not used for assembly and will be used for the
replacement if the original fuse were damaged.
Ensure all the following pieces are included with the Nakto Discov-
ery.
Assembly Instructions: Discovery
Tools included: Screwdriver, Phillips & Slotted 2 in 1
Double open-end wrench, 13mm/15mm
Allen wrench, 4mm
Allen wrench, 5mm
Tools needed: Scissor
Bike pump

2.Now stand the bike upright. Place some foam padding under the front
fork if placed on the ground or put it on bike assembly/repair stand if you
have one. We want to keep your bike looking new!
Step Two: Assemble the front wheel.
1.Loosen axle nuts on front wheel to make room for the front fork.
2.Lift the front of the bike and lower the fork onto the wheel axle. Notice:
The brake rotor should go into the brake caliper in between the brake
pads and the axle should enter the fork dropouts fully. The front rotor
orientation should be to the left of the fork.

3.Line up the axle lock washers (These are the metal washer with a bent
tab on one side) with the hole at each fork. Notice: These two special
fork lock washers keep the wheel from falling off if the axle nuts ever
loosen up! Tighten the axle nuts by hand.
4.Tighten both axle nuts with the supplied double open-end wrench.
Notice: Before doing the final tightening of the axle nuts，make sure the
wheel is square and true with the forks.

5.Push the black plastic nut caps onto the axle nuts.
Step Three: Install the handlebar.
1.Loosen the bolt on the top of the stem with the supplied allen wrench.
Remove the stem bolt and washer and set aside.

2.Remove and discard plastic spacer.
3.Install the handlebar onto the steer stem.

4.Pass the bolt through the washer mounting point and the stem mount,
tighten with the supplied allen wrench part away.
5.Align the stem so the handlebar is perpendicular to the front wheel. Use
the allen wrench to tighten the stem clamp bolts evenly (a half turn at a
time alternating between the two bolts).

6.Tighten the bolt on the top of the stem with the supplied allen wrench.
7.Perform a twist test.
(1).Brace the front wheel between your legs.
(2).Switch hands so the opposite hands are pushing and pulling with
about 20 pounds of force make sure the handlebar and front wheel are
still properly aligned.
(3).Repeat the twist test pulling/pushing with the opposite hands.

Step Four：Adjust the front brake system.
NOTICE: The The adjustment of the front brake system is not easy. The
following steps are only a general guide to assist in the adjustment of the
front brake system. Consult a certified, reputable bike mechanic to assist
with it.
The end goal is a caliper that is parallel to the rotor, with even gap
(2mm-3mm) on each side, and an adequate lever feel. Before adjusting
the front brake system, make sure the axle nuts in Step One have been
tightened.
1.Alignment procedure of the front brake.
Notice: Usually, all bike's rear brake were adjusted in the good condition
at factory. If not, alignment procedures are the same for front and rear
brakes. The end goal here is to keep 2mm-3mm clearance on either side
of the disc brake rotor so that the pads do not rub on the rotor when they
are not applied.

On the front disc brake caliper there are two bolts mounting it to the front
fork. Loosen the mounting bolts until the caliper body is able to freely
move side to side. Then squeeze the brake lever（this centers the caliper
body over the rotor）. While holding the lever, tighten the bolts. Release
the brake lever, spin the wheel and check for pad rub. If there is no
rubbing, the pads are aligned. Secure the mounting bolts to full torque
and your work is complete.

If the pads are still rubbing, we need to do some fine-tuning. Loosen one
bolt at a time and adjust until there is a gap on either side of the rotor.
Once the pads are not rubbing, fully secure each mounting bolt and the
process is complete.
To achieve proper gap, it is sometimes necessary to move pads by pad
adjusters. Calipers are equipped with pad adjusters that move the brake
pads in or out from the rotor. Notice: Turning the mounting bolt clock-
wise will move the pad closer to the rotor. Turning it counterclockwise
will move it away from it. Adjust the mounting bolt with the supplied
allen wrench.
2.Check and adjust the travel at the brake lever at the handlebars.
Typically, the pads should feel like they are contacting the rotor at a
minimum of 1/2 the lever travel. We will get it by adjusting the brake
cable tension.
Loosen the bolt on the end of the disc brake caliper arm with the supplied
allen wrench to adjust the brake cable tension. Once achieve the required
tension mentioned above, fully secure the mounting bolt and the process
is complete.

2.Attach the headlight to the fork arch. Pass the headlight mounting bolt
through the headlight mount and the fork arch mounting point. Thread
the locknut onto the bolt and tighten with the supplied screwdriver.
Step Five: Install the headlight.
1.Remove headlight mounting bolt from the fork arch with the supplied
screwdriver and set aside.

3.Center the headlight and adjust the angle slightly downwards to illumi-
nate the road ahead and not blind oncoming traffic. Use the supplied
Phillips-head screwdriver to loosen the headlight angle adjustment bolt,
tilt the headlight to the optimal position, and then tighten in place
securely.

Step Six: Install the seat.
1.Open the quick release lever by hinging it open fully.
2.Insert seat post into seat tube. Adjust the seat post up or down to a
comfortable height, while ensuring the seat post is inserted into the
frame past the minimum insertion point.

3.Close the quick release lever to secure the seat post and check that it
cannot move. If needed, use the thumb nut to add tension to the clamp
so there is some resistance when the lever is in line with the clamp bolt.

Step Seven: Install the pedals.
1.Locate the pedal with an “R” stamped into the end of the pedal axle,
which indicate it is the right pedal. The right pedal goes on the crank on
the right side of the bike. The remaining pedal with an “L” stamped into
the end of the axle, is the left pedal. The left pedal goes on the crank on
the left side of the bike.

2. The right pedals threaded to tighten by turning clockwise. The left
pedals reverse-threaded and tightens counterclockwise. Carefully thread
the pedal onto the crank by hand slowly.
3.Further tighten with the supplied double open-end wrench. Do not
cross thread or damage the threads.
Step Eight: Inflate the tires.
Check that the tire beads and tires are evenly seated around the rims. Use
a pump with a Schrader valve and pressure gauge to inflate each tire to
the recommended pressure indicated on the tire sidewall. Do not overin-
flate or underinflate tires.
Step Nine: Charge the battery.
Operate the electrical system when the battery has been adequately
charged and the battery is secured to the frame mount.
Your Nakto bike comes partially charged. We recommend you Connect
the charger input plug (110/220-volt plug) to the power outlet for 3 to 4
hours. The charger light will go from red to green when it is fully charged.

Step Ten: Ensure all hardware is tightened properly
following recommended torque values.

Quick Start Guide
This ebike is equipped with two ways for a rider to use power assistance
from the motor to propel the bike forward:
The pedal assist system (PAS) ⸺The rider can engage the pedal assist
system (PAS) while pedaling, and it will call up assistance from the motor
to help propel the bike forward.
The twist throttle⸺The throttle is located on the right side of the
handlebar. The rider can use it with a twist of the throttle grip to propel
the bike forward without pedaling.
Warning: The throttle is active whenever the bike is turned on. Do not use
the throttle unless you are on the bike.
Start-Up Procedure
1.Sit on the bike.
2.Turn on the electrical system⸺Press and hold the start button on
LCD display panel for approximately 3 seconds until power is delivered to
the LCD Display.
3.Turn on the headlight if needed or desired. Once the LCD Display is on,
press “CUR” button to turn the headlight on. Press it again to turn the
headlight off.
