Place bike upside down, insert assembled wheel
axle into the fork dropouts. Wind the axle nuts in by
hand at first. IMPORTANT: ensure the keyed washers
insert into the triangle holes on the dropouts.
4
Flip over, then push down firmly on the wheel
against the floor to correctly seat the hub in the
rim assembly.
3
Wind the collar off the hub. Insert the hub
assembly into the rim, valve side up (It will only fit
one way). You will need to rotate back and forth
as you push inwards to clear the inner flanges.
5
Flip back and check the hub has seated hard
against the rim assembly.
6
Wind the collar on by hand until it is against rim
assembly. Using a wrench or spanner gently
tighten 1/8 - 1/4 turn to ensure the hub is seated
firmly with no play. CAUTION: Do not over-tighten.

Pedals are marked ‘L’ & ‘R’ on the end of each
spindle. OG has a 1 piece crank and 1/2” thread
pedals, OG-PRO has a 3 piece crank with 9/16”
pedals.
NOTE: ‘L’ & ‘R’ are opposite thread to each other
so it is important to install on the correct side
to prevent cross-threading. This is not covered
by warranty.
10
Carefully insert the ‘L’ pedal on the left side and
start to wind in by hand. Then using your 15mm
spanner, (remember it is reverse thread! turn anti-
clockwise )and tighten. Make sure you do it up
nice and tight, loose pedals destroy thread fast!
Then repeat with the ‘R’ pedal on the right side,
so turn
clockwise and secure tightly.

View down the back of the disc. Align the brake
and tighten down B) the 2 x hex bolts with a 5mm
allen key. Ensure there is enough clearance both
sides so the disc does not rub. If there isn’t enough
clearance, the inside brake pad can be adjusted
back by removing the rear wheel to access
the 5mm hex adjuster on the back of the brake
closest to the wheel.
We’ll come back and hook up the brake once
the handle bars are on.
13
Position the seat at the desired height, and
tighten the clamp using a 4mm allen key.
Ensure the seat is aligned with the frame.
NOTE: Do not exceed the max height marking on
the back of the seat post.
11
Next step is aligning the brakes. This is easiest to
do before you fit the bars. Sit in a chair with the
rear wheel in your lap, front wheel on the ground.
This gives you a clear look down the back of
the disc. A) First loosen the cable clamp off with
a 5mm allen key. B) These are the hex bolts to
tighten the brake down once aligned.

Lightly tighten down two diagonally opposite until
it begins to pinch on the bars. Then rotate the
bars up and tighten slightly more to hold them in
place.
15
Undo the 4 x bolts with a 6mm allen key and
remove the stem plate. Ensuring all contact
surfaces are clean from grease or dust, place
the bars centred in the stem with the brake lever
to the right side, and hang them down in front.
HANDLE BARS

Check from the side to ensure the stem plate is
parallel with the stem, the gap both sides should
be equal. If not, back off the low side and slightly
tighten the other.

BAR ALIGNMENT / HEAD PARTS

NOTE: Stem bolts need to be tight! Work around
the bolts a few times to ensure it is securely
tightened down. Each time you tighten one bolt
it will allow you to get another partial turn on the
other bolts. A lot of force is put through the stem
when riding due to the amount of leverage on
the bars, you don’t want them to move!
19
Once you’re happy the bars are in the correct
position and the plate is level, work diagonally
opposite and tighten down each bolt.
21
First check if there is any play in the fork assembly.
You must also check the pinch bolts are secure.
However if the bars are out of alignment with the
front wheel, simply loosen the pinch bolts B) both
sides at the rear of the stem.
To tighten the fork assembly / head parts, with the
pinch bolts loose simply tighten A) the 5mm hex
bolt on top of the stem.
22
Once the bars are correctly aligned with
the wheel and there is no play in the head
parts / forks (bars must still turn freely),
secure the pinch bolts tightly with
a 6mm allen key.

IMPORTANT: Cut the cable approximately 2cm
from the clamp and replace the ferrule / cap
on the end of the cable to prevent it fraying and
causing injury. This will ensure the cable does not
get caught in the disc while riding.
29
Push the arm forwards until the outside brake
pad almost touches or lightly touches the brake
pad. Tighten the cable clamp using a 5mm
allen key. Then squeeze the brakes firmly a few
times, this will settle the cable and back the
adjustment off slightly. Before testing, spin the
wheel and check if there is any disc contact. If
so, undo the cable clamp and back the arm off
slightly then re-tighten.
31
Secure the cable to the top tube at both ends,
using the 2 x velcro ties.

Loosen the axle nuts on both sides with a 15mm
spanner.
CHANGING TYRES -
Wildcat’s split hub designs make it super easy to change tyres or access the tube to repair. No need for
tyre levers or force required. Below is the rear wheel instructions, with the Turbo wheel the easiest way is to
gain access to the tyre is through the driver side (the brake side will hold the axle assembly together). The
front is similar however minus the driver and brake making it much easier, just choose a side to open and
repeat the following steps.
3
Removing the disc is not 100% necessary, but it
does make life a bit easier when inflating and
balancing the tyre. The disc is simply threaded
onto the hub and is self-tightening when
brakes are applied. To remove insert a strong
screwdriver or similar through the disc and
carefully lever against the back of a spoke (so
as to not mark the front).
4
Once released / loosened the disc will simply
wind off by hand.

Using a 3mm allen key remove the 5 x hex hub
bolts on the driver side only.
5
NOTE: ENSURE THE TYRE IS DEFLATED BEFORE
CONTINUING. Remove the axle nut on the driver
side only.
7
Then remove the aluminium spacer. Sometimes it
is finger tight, but if required use a 17mm spanner
and a 4mm allen key in the axle for leverage. The
driver side assembly can now be lifted off the tyre
taking care to keep the driver seated in the hub.
No biggy if it comes out though!
8
Due to the internal locking system you may need
to slide the aluminium hub out of the rim, then
work around the rim pulling up firmly with your
hand to separate it. Once released both sides
can be removed from the tyre, then you have
access to change or fix the tyre.

9
Take care to replace the large spacer and
check it’s seated correctly before reassembly.
11
Replace the driver side onto the axle, again check
to see the valve slot on this side is aligned correctly.
12
If the driver did pop out, place it back on the axle
and holding the 3 x palls in gently rotate and push
it back in.
14
Replace the 5 x 3mm hex bolts and tighten down.
Replace the axle washer and nut.
13
Replace the spacer and wind down to hold the
assembly in place. Once together visually check
the large spacer between the hub halves is
correctly seated in both sides. It will have a little
slop until you tighten down the 5 x 3mm hub bolts.
CHANGING TYRES -

15
Partially inflate, just so the tyre lightly grabs the rim.
Take note of the bead line around the tyre close
to the rim edge. For balance you want the space
between this and the rim to be even the whole
way around on both sides.
16
To adjust, squeeze the tyre and position on
the rim. When you’re happy add a little air to
secure it then repeat on the other side.
To check balance,
hold up the wheel
and spin. You may
see a light visible
wobble but as long
as you cannot feel it
in your arms it will run
smooth. If it feels off
balance check the
bead line against the
rim both sides as it
spins to gauge where
you need to adjust.
Deflate and repeat.

19
Put the cap back on the valve, and wind the disc
back onto the mount firmly. Braking action will
further tighten the disc, so only needs to be tight
enough to prevent it dislodging during assembly.
20
Replace the wheel back onto the frame and loop
the chain back onto the chainwheel. Tighten axle
nuts by hand at first to align wheel and tension
chain, then fully tighten. Check alignment of disc
brake and adjust if required.
15
Once the spacing is relatively even, fully inflate to
the required pressure (40-50psi for Turbo wheel).

The disc is simply threaded onto the hub and
is self-tightening when brakes are applied. To
remove insert a strong screwdriver or similar
through the disc and carefully lever against the
back of a spoke (so as to not mark the front).
Unlike the Turbo wheel, to access the tyre and tube you must remove the disc from the wheel to split the
hub. Follow steps 1-2 for the Turbo wheel first.
