4. If misaligned, use a wrench to adjust the bolts.
5. Tighten the bolts securely after adjustment.

A properly aligned flywheel ensures smooth operation. Always check alignment if you notice unusual noises or resistance issues.

Flywheel Cleaning

Dust and debris can accumulate on the flywheel over time. Regular cleaning helps maintain performance. Follow these steps:

• Unplug the bike and remove any covers.
• Use a soft cloth to wipe the flywheel surface.
• Avoid using water or harsh chemicals.
• Check for any debris in the flywheel housing.
• Reassemble the covers securely after cleaning.

Keeping the flywheel clean extends the life of your bike. Clean the flywheel every few weeks for the best results.

Adjusting The Resistance

Adjusting the resistance on your Sunny Health & Fitness SF-B901 bike is essential for an effective workout. Proper resistance ensures you challenge yourself and meet fitness goals. Follow these steps to adjust the resistance accurately.

Cable Tension

The cable tension affects how smoothly your bike operates. Ensuring the right tension helps maintain the bike’s functionality.

• Locate the tension cable under the bike.
• Check for any signs of wear or damage.
• Use a wrench to adjust the cable if it feels loose.
• Ensure the cable is tight but not overly stretched.

Proper cable tension prevents unnecessary wear and tear. It also ensures a smoother ride.

Resistance Knob

The resistance knob allows you to control the difficulty level of your workout. It’s located on the main frame of the bike.

1. Turn the knob clockwise to increase resistance.
2. Turn it counterclockwise to decrease resistance.
3. Test the resistance by pedaling slowly.
4. Adjust until you find a comfortable yet challenging level.

Regularly check the resistance knob for any stiffness or looseness. Keeping it in good condition ensures a consistent workout experience.

If the knob feels stuck, apply a small amount of lubricant. This helps maintain its smooth operation.

Component	Action
Cable Tension	Adjust using a wrench
Resistance Knob	Turn clockwise or counterclockwise

These simple steps keep your Sunny Health & Fitness SF-B901 bike in top shape. Ensure you regularly check and adjust both the cable tension and resistance knob.

Addressing Noise Problems

Is your Sunny Health & Fitness SF-B901 bike making noise? Noise can ruin a good workout. Let’s fix it with some simple steps. We will focus on loose parts and lubrication.

Loose Parts

Loose parts can cause noise. Check all screws and bolts. Use a wrench to tighten any that are loose. Make sure the pedals and seat are secure. A loose pedal can be noisy and unsafe. Inspect the flywheel and make sure it is tight. If the flywheel is loose, it can wobble and make noise.

Part	Tool Needed	Action
Screws and Bolts	Wrench	Tighten
Pedals	Wrench	Tighten
Seat	Wrench	Tighten
Flywheel	Wrench	Tighten

Lubrication

Lubrication helps moving parts glide smoothly. Use a bike lubricant or WD-40. Lubricate the chain, flywheel, and pedals. Be careful not to over-lubricate. Wipe away any excess oil with a clean cloth. Check the resistance knob and lubricate it if it feels stiff. Proper lubrication can make your bike quiet and smooth.

• Chain: Apply lubricant and wipe off excess.
• Flywheel: A light coat of oil will suffice.
• Pedals: Lubricate the pedal threads.
• Resistance Knob: A small amount of lubricant can ease stiffness.
