- Insert Seat Post and Seat: Insert the seat post into the main frame and adjust to the desired height. Secure it with the adjustment knob. Attach the seat to the seat post.
- Montering af styrstolpe og styr: Sæt styrpinden ind i hovedstellet. Fastgør styret til stolpen, og fastgør det.
- Mount LCD Monitor: Connect the sensor wires from the main frame to the LCD monitor. Mount the monitor onto the designated bracket on the handlebars.

3.1 Adjusting the Bike for Your Comfort
Proper adjustment ensures an effective and comfortable workout while minimizing the risk of injury.
- Sædehøjde: Stand next to the bike. The seat should be approximately hip height. When seated, your knee should have a slight bend at the bottom of the pedal stroke. Adjust using the vertical adjustment knob on the seat post.
- Seat Fore/Aft Position: When pedals are horizontal, your front knee cap should be directly above the pedal spindle. Adjust using the horizontal adjustment knob beneath the seat.
- Styrhøjde: Adjust the handlebars to a comfortable height that allows for a slight forward lean without straining your back or shoulders. Use the adjustment knob on the handlebar post.

3.2 Modstandsjustering
The WENOKER JC312 features a "MAGPOWERΣ" magnetic resistance system, providing a quiet and smooth workout experience. The resistance is adjusted via a red knob located on the main frame.
- Øg modstanden: Turn the resistance knob clockwise. This increases the magnetic force on the flywheel, making pedaling more challenging.
- Reducer modstand: Turn the resistance knob counter-clockwise. This reduces the magnetic force, making pedaling easier.
- Nødstop: Press down firmly on the resistance knob to engage the emergency brake, bringing the flywheel to a rapid stop.

3.3 LCD Monitor Functions
The upgraded LCD monitor tracks your workout data in real-time. It is powered by batteries (not included).
- SCAN: Skifter automatisk gennem alle displayfunktioner med få sekunders mellemrum.
- TID: Viser varigheden af din aktuelle træningssession.
- HASTIGHED: Viser din aktuelle cykelhastighed.
- AFSTAND: Indicates the distance covered during your current workout.
- KILDTÆLLER (ODO): Displays the total accumulated distance since the monitor was reset or first used.
- KALORIER: Estimates the total calories burned during your workout.
To operate the monitor, ensure batteries are correctly installed. The monitor typically activates when you start pedaling or press a button. Consult the monitor's specific instructions for detailed operation and reset procedures.

The integrated tablet stand allows you to place a mobile device for entertainment or guided workouts during your session.
4. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer din motionscykels lange levetid og sikre drift.
- Rensning: Tør cyklen af med annonceamp en klud efter hver brug for at fjerne sved og støv. Undgå slibende rengøringsmidler eller opløsningsmidler.
- Inspektion: Periodically check all bolts, nuts, and moving parts for tightness. Re-tighten as necessary.
