3. Operating Instructions
3.1 Adjusting the Bike for Your Comfort
Proper adjustment ensures an effective and comfortable workout while minimizing the risk of injury.
- Seat Height: 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.
- Handlebar Height: 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 Resistance Adjustment
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.
- Increase Resistance: Turn the resistance knob clockwise. This increases the magnetic force on the flywheel, making pedaling more challenging.
- Decrease Resistance: Turn the resistance knob counter-clockwise. This reduces the magnetic force, making pedaling easier.
- Emergency Stop: 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: Automatically cycles through all display functions every few seconds.
- TIME: Displays the duration of your current workout session.
- SPEED: Shows your current cycling speed.
- DISTANCE: Indicates the distance covered during your current workout.
- ODOMETER (ODO): Displays the total accumulated distance since the monitor was reset or first used.
- CALORIES: 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.

4. Maintenance
Regular maintenance ensures the longevity and safe operation of your exercise bike.
- Cleaning: Wipe down the bike with a damp cloth after each use to remove sweat and dust. Avoid abrasive cleaners or solvents.
- Inspection: Periodically check all bolts, nuts, and moving parts for tightness. Re-tighten as necessary.
- Lubrication: The magnetic resistance system and belt drive are generally maintenance-free. Do not apply lubricants to the belt or flywheel unless specifically instructed by WENOKER customer service.
