This 200x50 inner tube for the Razor A5 Air kick scooter has the metric dimensions of 200 mm x 50 mm and the nominal inch measurements of 8" x 2". A small tire inner tube, it is a popular size on many top brands of electric scooters.

The Schrader valve stem is angled at 45 degrees to keep the tip away from the wheel's hub. Anyone who has ever experienced the skinned-knuckle pain and frustration of trying to get the air-fill chuck onto a straight stem will certainly appreciate the angled valve stem.
