Description
Inner ring / air hub 8 1/2x2" 50-134 (8.5x2"), 90 degrees - suitable for electric scooter Zero 8, 9, 8 Pro. The inner tube is suitable for fitting into 8 1/2x3 50-134 external tyres. Also fits inside 8 1/2x2" HOTA outer tyre. The valve on the inner tube is at a 90 degree angle and the plane of the inner tube is also at a 90 degree angle (see product picture).
NOTE: The 8 1/2x2" 50-134 HOTA inner ring is not suitable for use as an inner ring for the Xiaomi electric scooter, as the outer diameter of the inner pump (but the same size as the inner ring) is larger.
The inner hub of an electric scooter is an auto-valve (AV), which can be pumped by most pumps. Because of the small size and air volume of its tyres, the electric scooter is at risk of inner tube rupture due to impact, we recommend checking the tyre pressure once every 2 weeks or before each ride if the electric scooter is ridden less frequently. When inflating tyres, we strongly recommend the use of pressure gauge pumps to ensure the exact tyre pressure recommended by the electric scooter manufacturer. If your electric scooter is in need of repair or if a self-repairis too much for you, our specialist electric scooter workshop can help. We can also carry out tyre replacements on standby. You can read more about electric scooter tyre replacement in our blog post.
