5. Persediaan dan Pemasangan
Follow these steps to properly install your EBIKELING 8 Speed Freewheel:
- Remove the Old Freewheel (if applicable):
If replacing an existing freewheel, use a compatible freewheel remover tool and a large wrench or vise to unscrew the old freewheel counter-clockwise from the wheel hub. Ensure the wheel is securely held during this process.

- Prepare the Wheel Hub:
Clean the threads on your bicycle's rear wheel hub thoroughly. Apply a thin layer of grease to the hub threads to prevent seizing and facilitate future removal.
- Install the New Freewheel:
Carefully align the internal threads of the EBIKELING freewheel with the threads on the wheel hub. Begin threading the freewheel onto the hub clockwise by hand. Ensure it threads smoothly without resistance. If you feel resistance, stop, unthread, and re-align to avoid cross-threading.

Once hand-tight, use the freewheel remover tool and a wrench to tighten the freewheel securely. It does not need to be excessively tight, as pedaling forces will naturally tighten it further. However, ensure it is firm enough to prevent wobbling.

- Check Derailleur Alignment:
After installation, re-install your wheel onto the bicycle frame. Check your rear derailleur alignment and adjust it if necessary to ensure smooth and precise shifting across all 8 gears. Improper derailleur adjustment can lead to chain skipping or dropping.
6. Operating Your Freewheel
The EBIKELING 8 Speed Freewheel is designed for optimal performance with 8-speed drivetrain systems. When properly installed and adjusted, it will provide:
- Smooth Gear Transitions: Experience seamless changes between gears, enhancing your riding efficiency.
- Reliable Engagement: The internal mechanism ensures consistent power transfer from your pedals to the rear wheel.
- Operasi Bunyi Rendah: Designed for quiet performance during cycling.
Always shift gears gently and avoid shifting under heavy load to prolong the life of your freewheel and chain.
7. Penyelenggaraan
Regular maintenance will ensure the longevity and optimal performance of your freewheel:
- Pembersihan: Keep the freewheel clean from dirt, grime, and old lubricant. Use a degreaser specifically designed for bicycle drivetrains and a brush to clean between the cogs. Rinse thoroughly and dry.
- Pelinciran: After cleaning, apply a light bicycle chain lubricant to the freewheel cogs and the chain. For the internal bearings of the freewheel, it is recommended to apply a small amount of bicycle-specific grease during installation or if you notice any stiffness or noise. Note: Some freewheels may arrive with minimal internal lubrication; adding a small amount of grease can improve longevity.
- Pemeriksaan: Periodically inspect the freewheel cogs for signs of wear, such as hooked teeth or excessive thinning. Worn cogs can lead to poor shifting and chain skipping. Also, check for any lateral play or wobbling of the freewheel on the hub.
- Penggantian Rantai: A worn chain can accelerate wear on your freewheel. Replace your bicycle chain regularly according to manufacturer recommendations or when a chain wear indicator shows it is stretched.
