Quick Summary
This is a 2-pack of 18 inch bike inner tubes with Schrader valves, marked 38/50-355 and 18 x 1.50/1.95. The tubes are described as heavy duty and intended for bikes that use this size range, including mountain bikes, road bikes, cruiser bikes and e-bikes.
The main buying check is size and valve type. The tube must match the wheel size and the valve type used on the wheel rim. The pack quantity also matters if you are replacing more than one tube or keeping a spare.
