Remove the bike from the packaging. DO NOT dispose of the original packaging until
assembly is complete. Check all packaging to ensure all necessary components are found
before beginning assembly.
Step 1: Front wheel
1. Tu r n t h e f o r k u nt i l t h e fork plates are facing the front of the bicycle.
2. Insert the wheel into the fork.
3. Secure the wheel in place using an axle nut on either side of fork plates. Tighten the
axle nuts by hand.
4. Ensure the wheel is centred equally between the fork before tightening the axle
nuts using the M15 spanner.
ASSEMBLY

Step 2: Front and rear fenders
1. Attach the front fender hanger and the front reflector to the fork crown.
2. Attach the rear fender hanger to the mid tube of the frame.
3. Make any necessary adjustments to the fenders and front reflector, then tighten
the screws to secure them in place.
Step 3: Front brake adjustment
Note: The front V-brakes have been pre-installed at the factory, however they will need to be
adjusted after assembling the front wheel and fender.
1. Use the M5 Allen key to loosen the brake cable bolt and adjust the tension in each
brake arm. Ensure both sides are equally and properly tensioned.
2. After ensuring that the clearance between both brake pads and the rim is between
2-3mm, tighten the brake cable bolt.
Note: Do not ride the bike unless the brakes have been properly tested.

Replacing brake pads:
When the brake pad wear grove is no longer visible, the brake pads will need to be replaced.
1. Use the M6 Allen key to release the brake mounting bolt on the brake pad.
2. Replace the brake pads and ensuring they are properly adjusted to fit the rim
perfectly.
3. Use M6 Allen key to tighten the bolt.
WARNING: If the brake pads are not replaced it can lead to an accident,
serious personal injury and cause permanent damage to your wheels.

Step 4: Handlebar & stem
1. Insert the stem into the fork tube to the minimum insertion line, as indicated on the
stem pillar.
2. Face the handlebar stem forward directly in line with the front wheel. Torque the
handlebar stem pillar bolt to 12-15 ft. lb. or 17-19 N m.
3. Use the stem quick release to lock the stem in place.
4. Adjust the handlebar position and ensure that the stem minimum insertion mark is
completely inserted into frame and not visible. Lock the handlebar in place using
the handlebar quick release clamp.
WARNING: If the handlebars can forward or backward, the quick release
clamp bolts are not tight enough and should be adjusted.
WARNING: Overtightening the quick release bolt can cause damage to the
handlebar stem assembly and lead to potential injury of the rider.

Gear adjustment:
The right shifter controls the 7 speeds (freewheel) of the bicycle. Turn the shifter to switch
between different gear ratios in order to change pedal speed.

Step 5: Seat post
1. The seat has been pre-assembled to the seat post by the factory.
2. Insert the seat post into the bicycle frame. Ensure that seat post minimum insertion
mark is completely inserted into the frame and not visible.
3. Adjust the seat position and tighten the quick release clamp at the desired height.
Note: Rotating the quick release nut clockwise while keeping the cam lever from
moving will increases the clamping force. Rotating the quick release nut counter-
clockwise while keeping the cam lever from moving will reduce the clamping force. Less
than half a turn of the nut can make the difference between a safe and unsafe amount
of clamping force.
4. Adjust angle of seat so that top of seat is parallel to the ground and comfortable to
the rider.
Note: Te s t t h e s e a t to p e d a l d i s t a n c e b y h a v i n g t h e r i d e r s i t o n t h e s e a t . W h e n t h e
rider’s leg is slightly bent, the ball of the foot should rest on the pedal when it is in its
lower position. If not, adjust the seat height accordingly.
WARNING: If the seat is able to twist, the quick release nut is not tight enough
and should be adjusted.

Step 6: Attaching the pedals
1. Attach the pedal marked “R” onto the crank arm on the “chain side” of the bike.
Securely tighten the pedal in a clockwise direction.
2. Attach the pedal marked “L” onto the crank on the left side of the bike. Securely
tighten the pedal in a counter-clockwise direction.
3. Torque the pedals to 18-20 ft-1bs or 20-26 N m.
Note: To a v o i d s t r i p p i n g t h e t h r e a d s , s t a r t t i g h t e n i n g e a c h p e d a l b y h a n d b e f o re
using hand tools.
WARNING: For safe operation, the pedals must be securely tightened onto the
crank arms.

Step 7: Rear reflector
1. Loosen the screws on the rear reflector bracket and attach the rear reflector to the
seat post.
Note: It is important to check and adjust the position of the reflector. The reflector
must always be vertical (perpendicular to the ground) and pointed toward the rear
of the bike.
2. Check there is at least 7.62 cm of clearance between the top of the seat and the
top of the rear reflector. Tighten the screw on the rear reflector bracket.
Step 8: Bell
1. Loosen the screw on the bell and attach it to right side of the handlebar in the
position shown below.
2. Secure the bell in place by tightening the screw.

Release the clamp and open the frame quick
release.
