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.
