Duše CST 90/60-6.5 pro KAABO Wolf King

High-quality CST inner tube for electric scooters

Choosing a reliable, high-quality inner tube is crucial to prevent punctures or air loss on your electric scooter.

In the eVolt service network, we have tested numerous inner tube brands and selected only those that perform best on powerful scooters, as they are made from premium rubber materials and valves.

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

Inner tubes of size 90/60-6.5 fit tire sizes 90/60-6.5, 100/60-6.5, and 110/60-6.5.

Preventing a flat tire

The most common cause of flat tires is riding with incorrect inner tube pressure. 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 of the inner tube
• Wear of the tire from the inside and outside
• Poor grip and increased risk of slipping
• Longer braking distances
• Worse handling characteristics

Valves on scooter inner tubes can be difficult to access, so we offer a valve extension that greatly facilitates inflation.

Service information

Improper installation of the inner tube can cause problems such as:

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

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

For proper, professional inner tube replacement and inspection, visit the nearest eVolt service center in our network.
