Assembly Instructions
Follow these steps carefully to assemble your RIF6 Exercise Bike. It is recommended to have two people for certain steps due to the weight of the main frame.

Operating Instructions
Adjusting Riding Position

Figure 2: Adjustable Seat and Handlebar. This image illustrates how to adjust the seat height (from 26 to 30 inches) and handlebar height (from 39 to 44 inches) using adjustment knobs for a customized riding position.
- Seat Adjustment: Loosen the adjustment knob below the seat. Slide the seat post up or down to your preferred height (26-30 inches). Ensure your leg has a slight bend at the knee when the pedal is at its lowest point. Tighten the knob securely. The seat can also be adjusted horizontally.
- Handlebar Adjustment: Loosen the adjustment knob on the handlebar post. Raise or lower the handlebars to a comfortable height (39-44 inches). Ensure your back is straight and your arms are slightly bent. Tighten the knob securely.
Tension Control

Figure 3: Tension Control. This image shows the red tension knob located on the main frame, with arrows indicating clockwise to increase resistance and counter-clockwise to decrease resistance.
The tension control knob allows you to adjust the resistance level of your workout. Turn the knob clockwise to increase resistance for a more challenging ride, and counter-clockwise to decrease resistance for an easier ride. To stop the flywheel quickly, press down firmly on the tension knob.
LCD Monitor Functions

Figure 4: LCD Monitor. This image displays the LCD monitor with its various readouts: Time, Speed, Distance (DST), Calories (CAL), and Pulse. It also shows the 'SET', 'RESET', and 'MODE' buttons.
The integrated LCD monitor tracks your workout data. Use the "MODE" button to cycle through different display functions:
- TIME: Displays the duration of your workout.
- SPD (Speed): Shows your current cycling speed.
- DST (Distance): Tracks the distance covered during your workout.
- CAL (Calories): Estimates the calories burned.
- PULSE: Displays your heart rate when holding the heart rate sensors on the handlebars.
- SCAN: Automatically cycles through all functions every few seconds.
Use the "SET" button to set target values for time, distance, or calories. Press "RESET" to clear all workout data.
Heart Rate Sensor

Figure 5: Heart Rate Sensors. This image highlights the two metallic sensors integrated into the handlebars, which are used to measure the user's heart rate and display it on the LCD monitor.
To measure your heart rate, firmly grasp the metallic sensors on both handlebars. Your pulse will be displayed on the LCD monitor after a few seconds. Ensure your hands are clean and making good contact with the sensors for an accurate reading.
Tablet Holder

Figure 6: Tablet Holder. This image shows a tablet securely placed in the holder located above the LCD monitor, alongside a water bottle in its holder, demonstrating how users can integrate entertainment or fitness apps during their workout.
The integrated tablet holder allows you to place your smartphone or tablet for entertainment or to follow guided workouts during your exercise session.
Transport Wheels

Figure 7: Transport Wheels. This close-up image shows the two small wheels located on the front stabilizer bar, designed to facilitate easy movement and relocation of the exercise bike.
To move the exercise bike, tilt it forward by lifting the rear stabilizer until the transport wheels on the front stabilizer make contact with the floor. Carefully roll the bike to its desired location.
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 and nuts for tightness. Tighten any loose fasteners.
- Lubrication: The belt drive system is generally maintenance-free. If you notice any squeaking from the flywheel or pedal mechanism, a small amount of silicone-based lubricant can be applied to pivot points, avoiding the belt itself.
- Storage: Store the bike in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LCD Monitor not displaying | Batteries are dead or incorrectly installed. Loose connection. | Replace batteries (if applicable). Check all cable connections to the monitor. |
| Squeaking noise during operation | Loose bolts or parts. Lack of lubrication on moving parts. | Inspect and tighten all bolts. Apply a small amount of silicone lubricant to pedal axles or other pivot points (avoiding the belt). |
| Resistance not changing | Tension knob not properly engaged or worn friction pad. | Ensure the tension knob is fully engaged. If the issue persists, contact customer support. |
| Pedals feel loose | Pedals are not tightened sufficiently. | Retighten pedals firmly. Remember the left pedal is reverse-threaded. |
