From the manufacturer, the first and most important consideration when selecting a tube is to ensure it fits your tire. To determine the size you need, check the sidewall markings on your tire, where you'll see two numbers separated by an 'X'. The first number refers to the tire's diameter, and the second number refers to the tire's width. Select the tube that has the exact same diameter as your tire, and make sure your tire's width falls within the range of widths listed on the tube packaging.

Valve type is another crucial factor. Standard (Schrader) valves are the most common for bicycles, as they are also used on car tires and other inflatables. Presta valves, on the other hand, are typically found on performance road and mountain bikes. They have built-in valve locks that you twist to open before inflating. An easy way to remember is: 'S' is for Standard (Schrader, Short, Sturdy), and 'P' is for Presta (Performance, Premium).

All inflatable tubes are subject to deflation from improper installation and certain hazards. Therefore, you'll need to choose whether to go with a standard or self-sealing tube. Standard tubes are suitable for most riding conditions, while self-sealing tubes have liquid sealant inside that provides an extra layer of flat protection by instantly sealing holes up to 1/8 of an inch while you ride. This makes flat repairs much easier.

The Bell Kids Tires, Bell BMX Tires, Bell MTB Tires, and Bell Cruiser Tires all feature standard tire types, while the Bell Floor Pumps provide a convenient way to inflate your tires. The customer reviews for the Bell Floor Pumps are impressive, with a 4.6 out of 5-star rating based on 2,399 reviews.

The standard tire option is available for all the Bell tire models, ensuring consistent sidewall protection and preventing high-pressure blowouts. The flat defense tire, on the other hand, is only available for the Bell BMX Tires, Bell MTB Tires, and Bell Cruiser Tires, providing an additional layer of flat protection.

The high-quality, reliably tested inner tube from the manufacturer features a Schrader valve and weighs 160g, making it suitable for kid and BMX tires. The 35mm valve length with a cap ensures a secure and easy-to-use inflation experience.
