Inner Tube 8.5 x 2 90° Bent Valve

This inner tube is designed for electric scooters and other vehicles requiring an 8.5 x 2 tyre size. It features a 90° bent valve for easier access during inflation.

You can choose between two quality options:

  • CST - thickened: A robust option for enhanced durability.
  • Original: A standard replacement inner tube.

Compatibility and Fitment

This inner tube is suitable for tyres marked 8.5 x 2.0. It may also be compatible with tyres sized 8.5 x 3.0, 9 x 2.0, and 9 x 3.0. Always verify the full tyre sidewall marking and the valve hole arrangement on your rim before ordering.

This part is applicable to:

  • ECO Speed 9
  • Vsett 9
  • Vsett 9+
  • ECO Speed 8 (2021 – front wheel)

Installation and Safety Guidance

Proper installation and maintenance are crucial for the longevity of your inner tube and tyre, as well as for safe riding. When replacing an inner tube:

  • Inspect the Tyre: Carefully check the inside and outside of the outer tyre for any sharp objects, punctures, or damage that could compromise the new inner tube. A damaged outer tyre can quickly lead to a new flat.
  • Valve Orientation: Ensure the 90° bent valve is correctly aligned with the valve hole in the rim to prevent stress on the valve stem.
  • Avoid Pinching: During installation, take care not to pinch the inner tube between the tyre bead and the rim. Partially inflating the inner tube before seating the tyre can help prevent this.
  • Seating the Tyre: Ensure the tyre beads are fully and evenly seated on both sides of the rim before full inflation.
  • Inflation: Inflate the inner tube to the pressure recommended by your scooter or tyre manufacturer. Riding with incorrect pressure can lead to inner tube damage, premature tyre wear, reduced grip, longer braking distances, and poor handling.
  • Post-Installation Check: After inflation, visually inspect the tyre and inner tube for any bulges or signs of improper seating.
