Duše CST 90/60-6.5 pro ECO Speed 20X

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.

Based on our experience and 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 tires of size 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 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 to the inner tube
• Wear of the tire from the inside and outside
• Poor grip and increased risk of skidding
• Longer braking distances
• Poorer riding characteristics

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

Service information

Incorrect inner tube installation 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 changing 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 correct, professional inner tube replacement and inspection, visit the nearest eVolt service center in our network.
