3. Using the bike
3.1. Riding the bike
Before each start, make sure that your bike is technically sound and check the
following items in particular:
• Properly tighten the screws.
• Fasteners or any parts of the bicycle are not damaged.
• Is the ride position adequate?
• Proper steering wheel alignment.

• Wheel adjustment.
• Appropriate tire pressure.
• Pedal adjustment.
• Derailleurs are adjusted appropriately.
• The lighting is properly set.
After checking all the above items, make sure that the cables in the bike are not
damaged and are in the correct position. Every 6 months, the bike should be
provided with a comprehensive service at any service point to ensure that the
user is completely safe while using.
3.2. Self-assembly
Below you will find useful information about the installation of our bicycles,
especially those that require self-assembly:
Step 1: Preparation:
Pull the bike out of the carton with all the components in it. Be careful not to
scratch your bike and be careful not to damage any cables or other
components. Make sure your bike does not miss any items.
Step 2: Assemble the seat
1) Unscrew the clamping nuts (on both sides).
2) Insert the seat into the frame.
3) Tighten the seat bolts on both sides.
4) Unscrew the saddle on the saddle yoke and then slide the seat end up or
down so that it is parallel to the ground.

Step 3: Pedal mounting
1) The pedals on the axle are marked with the letter "R" or "L".
2) Tighten the pedal by the letter "R" clockwise in the clockwise direction. Then
tighten it with key # 15 with a force of 34 Nm.
3) Tighten the pedal by the letter "L" on the left counterclockwise. Then tighten
it with key No. 15 with a force of 34 Nm.
Step 4: Adjust the brakes
The brakes should be set up already at the factory, but the cables tend to
deregulate, so they need to be checked after the first test drive. Adjustments
should also be made during use of the bicycle in case of necessity. If you need
additional consultation, please contact a professional cycling center.
Step 5: Install the front wheel
The front wheel is disassembled, so after opening the carton, remove the
protective foil and fit on the front fork.

Then, use the pin.
3.3. How to adjust the saddle height to suit the rider.
3.4. Precautions required prior to each use
Verify that the brakes and the front & rear lights are all working properly. Also,
check the pressure of the tires.
On derailleur geared bicycles the rear derailleur automatically tensions the
chain.

Make sure that the hinges on your bike are properly locked. Indeed, when
using the bike on a regular basis, the tension of the hinges’ adjustment and
locking systems can change slightly. Whenever necessary, adjust the tension
once again.
This bike is not designed for rough usage condition, such as jumps, riding up or
off of pavements, and riding on unpaved roads. For your own safety, do not
modify the bike.
Please note: if you use the bike frequently, it is recommended that you
inspect the state of the fork, the frame, the suspension and the fasteners. The
materials and components may be subject to different reactions to usage and
wear.
If you have any doubts, contact your dealer, who will proceed with the
necessary inspection.
