Assembly

Before riding, ensure that all required fasteners are tightened to the correct torque. • Ensure

that the tyres are inflated to within specification (printed on the tyre sidewall), and that the

brakes are operating correctly. • Assembly may require 2 people. • Do NOT allow children to perform the

assembly. • Additional tools to those supplied (if any) may be required for assembly, such as a torque

wrench, pliers etc.

The bicycle comes with some minor assembly required, and may include some necessary tools.

Handlebars

1. Carefully place the bicycle assembly on a flat surface so that

it rests on the front fork and rear wheel.

2. The handlebar clamp (A) comes pre-assembled and should

not require any adjustment, however, may be facing the rear

of the bike (for shipping reasons). Loosen (rotate left) the 2

clamp screws (B) using a 5mm Allen key, then rotate the

handlebar clamp so it is facing forward. Note that the fork

brace (C) faces forward. Firmly tighten (rotate right) the

clamp screws.

3. Check for any forward –

backward movement in the

steering stem by holding the

forks firmly and pulling-pushing

the handlebar clamp. If any

rocking can be seen or felt,

remove the rubber cap (D) at

the top of the steering stem (E),

then using a 5mm Allen key,

tighten (rotate right) the top screw (F) sufficiently to remove

any movement. Ensure that the top screw is not so tight as to

bind the handlebar and make it difficult to rotate.

4. Remove (rotate left) the 4 handlebar yoke screws (G) using a

4mm Allen key, then remove the yoke (H).

5. Place the handlebar assembly (I) centrally into position in the

clamp. Rotate it so it is in a comfortable position and the

levers / controls are in easy reach of your fingers, then re-

install the yoke. Note that the display faces rear and the

brake levers face forward. Using a 4mm Allen key and torque

wrench, tighten the yoke screws to the specified torque.

6. Loosen (rotate left) the 2 handlebar clamp screws (B)

slightly, then rotate the handlebar assembly, as required,

so it is aligned "square" to the front fork. That is, the

handlebar will be at 90° to the bicycle frame when the

front wheel is straight, then using a 5mm Allen key and

torque wrench, tighten the handlebar clamp screws to

the specified torque.

The orientation of the front fork is correct when the

axle is facing forward. The orientation of the

handlebar is correct when the control cables and brake levers are

facing forward. It is ESSENTIAL that the fork and handlebar are

assembled correctly. The adjacent image shows correct fork /

handlebar assembly.

Seat

When setting seat height, it is important to ensure that the resulting ride position is not only

comfortable, but also safe. You should be able to remain stable and properly handle the bicycle

when at a standstill, touch the ground etc. You should also be able to comfortably reach the pedals

when riding and comfortably and safely operate the handlebars and all controls. A good reference height for

the seat is at hip height. Do NOT have the seat raised enough so you can see the maximum height marker

on the seat post. • Ensure that when the seat is clamped, you cannot rock it back and forth or rotate it.

1. Insert the seat post/seat assembly (J) into the bicycle frame and lower it to a comfortable position – do

NOT have the seat raised enough so you can see the maximum height marker (K) on the seat post.

2. Rotate the clamp lever (L) from the unlock position (AA) to the lock position (BB). If the seat post is not

clamped firmly, increase pressure by unlocking the clamp, then rotating the adjustment knob (M) right

(clockwise) a ¼ turn, then re-test and adjust as necessary.

The seat angle can also be adjusted, again for best comfort. To

adjust angle, using a 13mm spanner, loosen (rotate left) the seat

clamp nuts (CC) on either side of the seat until the front of the

seat can be moved up/down. Set the angle as required, then

tighten the nuts securely.

Note that small changes in seat position can have a substantial

effect on comfort. It is recommended to make seat adjustments in

small increments and test the position, then re-adjust as

necessary.

Front Wheel

It is ESSENTIAL that the wheel quick-release mechanism is installed and adjusted

correctly. Failure to do so will render the bicycle as dangerous. If you are in any way

unsure about installing and adjusting the quick-release, take the bicycle to an authorised service

centre or qualified bicycle mechanic. • For bicycles with disc brakes, install the quick-release so the lever

is NOT on the brake side.

1. Turn the bicycle over so it is resting on the handlebar and seat – ensure it is not resting on the

console.

2. Install the front wheel (N) by lowering it into the fork legs, so that the hollow axle (O) rests in the slots

at the bottom of the fork legs. Ensure that the brake disc (P) is on the same side as the brake caliper

(Q) and that the disc enters the caliper.

3. Remove the nut (DD) and spring (EE) from the quick-release (R) ("skewer"), then insert the quick-

release through the axle from the non-brake side.

4. On the threaded end of the quick-release, re-install the spring, small diameter first, and nut. Screw the

nut on, then rotate the quick-release lever (FF) toward the locked position – you should feel resistance in

the lever starting at about the halfway point in its rotation. The resistance is the ends of the quick-release

pushing the forks against the wheel axle. Continue rotating the lever to the fully closed position – it

should take some force to do this – if you cannot push the lever to the fully closed position, or it is very

easy to do so, adjust the quick-release nut (DD) as required until the is (a) wheel is fully secured by the

quick-release when the lever is in the closed position, and (b) the quick-release lever requires

reasonable force to reach the fully closed position.

To remove the wheel, rotate the quick-release lever to the fully unlocked position, then carefully pull the

wheel out from the bicycle forks.

Pedals

It is critical that you follow the pedal to crank arm attachment procedure carefully to ensure

correct assembly. • During assembly, do NOT use excessive force to screw the pedals into the

crank arms – this may indicate misalignment of the pedals or mis-matched threads. If the pedal does not

"feel right" when being screwed in, STOP immediately and check that it is the correct pedal and that it is

aligned properly with the crank arm. Failure to follow the instructions here or take due care may

damage the equipment and void any product warranty.

1. Starting with the right-hand crank arm (S), identify the right-hand pedal assembly (T), which is identified

by having the pedal bolt stamped "R".

2. Very carefully begin screwing the pedal bolt into the crank arm (rotate right / clockwise). If the bolt does

not "feel right" when being screwed in, STOP immediately and check that it is the correct bolt and that it

is aligned properly with the crank arm. Screw the pedal bolt in fully, then tighten to the specified torque

using a 15mm spanner and torque wrench.

3. Repeat the above procedure for the left-hand crank arm, noting that the pedal bolt and crank arm

thread is left-hand (rotate left / anti-clockwise to tighten) and that the pedal bolt is stamped "L".

Ancillary Parts

•Attach the headlight (U) and front mudguard (V) (if applicable) to the

fork brace (W) using the 6mm bolt and nut. Firmly tighten the fastener

using a 10mm spanner, then rotate the headlight to a suitable angle.

•Attach the rear mudguard bracket (X) to the rear frame brace (Y) using

the 6mm bolt and nut. Firmly tighten the fastener using a 10mm

spanner. Using a screwdriver, attach the mudguard (Z) to the bracket

using the 2 mudguard screws (A1).

Assembly is complete. The bicycle should resemble the following
