Inner Tube CST 90/60-6.5

High-Quality CST Inner Tube for Electric Scooters

Choosing a reliable, high-quality inner tube is essential for preventing punctures or air loss on your electric scooter.

At the eVolt service network, we tested many inner tube brands and selected only those that perform best on powerful scooters, featuring top-grade rubber and valve materials.

From our experience and customer feedback, CST inner tubes have proven to be the most durable and highest quality choice.

Inner tubes sized 90/60-6.5 fit tires sized 90/60-6.5, 100/60-6.5, and 110/60-6.5.

Preventing Flat Tires

The most common cause of flat tires is riding with incorrect pressure in the inner tube. Most electric scooters require at least 3.5 bar, which should be checked regularly with a pressure gauge—ideally once a week.

Using incorrect inner tube pressure can lead to:

• Damage and punctures to the inner tube
• Wear to the tire from the inside and outside
• Poor grip and a higher risk of slipping
• Longer braking distances
• Poor handling characteristics

The valve stems on scooter inner tubes can be hard to access, so we offer a valve extender that makes inflating much easier.

Service Information

Improper inner tube installation can cause issues such as:

• Damage to the motor cable
• Damage to the motor frame
• Sharp cuts on the rim
• Damage to both the tire and new inner tube

When replacing a flat inner tube, always check the condition of the outer tire. A tire damaged by incorrect pressure will quickly ruin a new inner tube.
