CST 90/60-6.5 inner tube for ZERO 11X / ECO Speed 11X

High-quality CST inner tube for electric scooters

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

In the eVolt service network, we have tested many brands of inner tubes and selected only those that perform best on powerful scooters, as they are manufactured from premium rubber and valve materials.

Based on our experience and customer feedback, CST inner tubes have proven to be the most durable and high-quality choice.

Inner tubes size 90/60-6.5 fit tires with sizes 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:

• Inner tube damage and punctures
• Tire wear from the inside and outside
• Poor grip and higher risk of slipping
• Longer braking distances
• Worse handling characteristics

Valves on scooter inner tubes can be difficult to access, which is why we offer a valve extension, which makes inflating much easier.

Service information

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

• Motor cable damage
• Motor housing damage
• 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 due to 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.
