Setup and Assembly
Follow these step-by-step instructions to assemble your DS25 Indoor Fitness Bike. It is recommended to have two people for assembly to ensure safety and ease.
Step 1: Attach Stabilizers
Secure the front and rear stabilizers to the main frame using the provided bolts and washers. Ensure all fasteners are tightened firmly to provide a stable base for the bike.
Step 2: Install Pedals
Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Thread them carefully into the crank arms by hand first, then tighten with the provided wrench.
Step 3: Mount Saddle
Insert the saddle post into the frame and adjust to your desired height. Secure it firmly with the adjustment knob. Attach the saddle to the post, ensuring it is level and comfortable.
Step 4: Attach Handlebar
Insert the handlebar post into the frame and adjust to your preferred height. Secure it with the adjustment knob. Attach the handlebar assembly, ensuring all connections are tight.

Operating Instructions
Proper adjustment and operation will enhance your workout experience and ensure safety.
Adjusting Seat and Handlebar
For optimal comfort and performance, adjust the seat height, fore/aft position, and handlebar height to suit your body. The seat post features CP treatment for anti-corrosion properties, ensuring smooth adjustments over time.

Adjusting Resistance
The DS25 features a magnetic resistance system for smooth and quiet operation. Turn the graduated adjustment knob clockwise to increase resistance, making pedaling harder. Turn it counter-clockwise to decrease resistance, making pedaling easier.

Emergency Stop
To stop the flywheel quickly in an emergency or at the end of your workout, press down firmly on the resistance adjustment knob. This will engage the emergency brake.
Using the Workout Display
The integrated workout display provides real-time feedback on your exercise session. It typically shows metrics such as time, distance, speed, and calories burned. Refer to the display's specific instructions (usually found on the display itself or in a separate mini-manual) for navigation and mode selection.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your BODYTONE DS25.
Regular Cleaning: After each use, wipe down the bike with a damp cloth to remove sweat and dust. Avoid using abrasive cleaners or solvents, which can damage the finish.
Check Connections: Periodically inspect all bolts, nuts, and moving parts for tightness. Tighten any loose fasteners as necessary to maintain structural integrity.
Lubrication: The magnetic resistance system is generally maintenance-free and does not require lubrication. If you notice any unusual noises from moving parts, contact customer support.
Belt Inspection: Annually, or if you notice any issues, inspect the Poly-V belt for signs of wear, cracks, or damage. Belt replacement should be performed by a qualified technician.
Storage: Store the bike in a dry, cool place away from direct sunlight, extreme temperatures, and high humidity to prevent corrosion and material degradation.

Troubleshooting
This section addresses common issues you might encounter with your DS25 Indoor Fitness Bike.
Squeaking/Unusual Noise: Check for any loose bolts or parts, especially around the pedals, crank arms, and stabilizers. Ensure the bike is placed on a completely level surface. If the noise persists after checking all connections, contact customer support.
Resistance Issues: If the resistance feels inconsistent or does not change when adjusting the knob, ensure the adjustment knob is functioning correctly and not obstructed. Verify that no foreign objects are interfering with the flywheel or the magnetic resistance mechanism.
Workout Display Not Working: Check the battery compartment for proper battery insertion and ensure the batteries have sufficient charge. Replace batteries if necessary. If the display still does not function, contact support.
Pedals Feel Loose: Re-tighten the pedals firmly. Remember that the left pedal is reverse-threaded (tightens counter-clockwise), while the right pedal tightens clockwise.
For issues not listed here, or if troubleshooting steps do not resolve the problem, please contact BODYTONE customer support for assistance.
