What Causes the Clicking Sound in the Rear Wheel of a Scooter?
2 Answers
The causes of clicking sound in the rear wheel of a scooter are as follows: 1. Damaged rear wheel bearing: If there is abnormal noise in the rear wheel of the scooter, it could be due to a damaged rear wheel bearing or long-term wear of the pulley sleeve. However, the noise caused by the pulley issue is usually not very loud. If the problem lies with the pulley, it can only be resolved by replacing it with a compatible part of the same model. 2. Extent of damage: In cases of minor damage, you may feel a consistent bumping sensation, as if going over a bump every full rotation or every few rotations. When the damage is moderately severe, a clicking sound may occur just by sitting on the scooter. In the most severe cases, the rear wheel may lock up completely, making it impossible to rotate and requiring the scooter to be dragged.
I often repair my friends' scooters, and a clicking noise from the rear wheel is mostly due to chain or transmission issues. If the chain is too loose or rusty, it will creak while riding, sounding like a clicking noise. Another common cause is gear wear, especially when starting or going uphill—worn gears can produce a grinding sound. It could also be a bad bearing, such as rusted or deformed ball bearings in the rear wheel, which make noise when the wheel turns. For CVT transmissions, clutch slippage or wear can cause similar sounds. I remember once, during an inspection, I found a small stone stuck in the brake disc—it made a clicking noise when rubbing. This needs immediate attention, as riding with such issues is dangerous; a broken chain could lead to a crash. It's best to clean the chain and lubricate the gears regularly, and a monthly check can prevent these problems.
