The 2.80/2.50-4 inner tube for the Razor E-XR (Version 1+) and E300 (Version 40+) electric scooter comes with an angled valve stem which makes refilling far easier.
Note: This tube may also fit some late-production E300 Version 40 scooters. Most earlier E300 scooters used the 3.00-4 Razor E300 tire and inner tube, but those Version 40 tires made at Razor Factory #40 use the 2.80/2.50-4. If you have a Version 40 E300 scooter please look on the sidewall of your old tire. If it says "2.80/2.50-4" then this is the replacement tube that will fit your Razor.
