Inner tube 20x1 95

Everything you need to know about the 20x1.95 inner tube: features and specifications

The 20x1.95 inner tube is an essential part of any bike tire, especially popular for kids’ bikes, BMX models, and some compact MTBs. Whether you're riding through the city, tackling off-road trails, or hitting the skatepark, choosing the right inner tube for your tire is key to ensuring comfort, safety, and performance. Here's a closer look at this specific size, its technical features, and what you need to know before buying.

What is a 20x1.95 inner tube ?

The label 20x1.95 refers to the dimensions of the bike tire:

• 20 inches: the outer diameter of the tire

• 1.95 inches: the width of the tire

A 20x1.95 inner tube is therefore designed to fit a 20-inch bike tire with a width between approximately 1.75 and 2.125 inches. This size is common on BMX bikes, folding bikes, and some junior mountain bikes.

Technical features

Here are the key factors to consider before purchasing a 20x1.95 inner tube:

Compatibility

Make sure it matches your 20-inch bike tire. Check the markings on the tire sidewall (e.g., 20 x 1.95 or ETRTO 50-406) to ensure compatibility.

Valve type

Two valve types are generally available:

• Schrader valve (car valve): wider, the same as car tires. Ideal for BMX and mountain bikes.

• Presta valve (narrow): slimmer, often found on road bikes or lightweight bicycles.

Make sure your rim is compatible with the valve type you choose.

Material

Most inner tubes are made of butyl rubber, a synthetic material resistant to air loss and temperature variations. Some brands offer latex tubes, which are lighter but more delicate.

Weight and thickness

A thinner inner tube reduces rolling resistance but is more prone to punctures. A reinforced model provides better protection against pinches and sharp objects when riding off-road.

Why replace a 20x1.95 inner tube?

You might need to replace your inner tube if:

• The tire loses air regularly

• There’s a visible puncture or pinch

• Multiple patches have weakened the rubber

Replacing the bike inner tube restores the tire’s airtightness and ensures a balanced, smooth ride. It's a small maintenance task that makes a big difference in comfort and safety.

Good to know: pressure and maintenance

The recommended pressure for a 20x1.95 tire is generally between 36 and 58 PSI (2.5 to 4 bar), depending on the type of bike and rider weight. Keeping your bike tire properly inflated helps prevent pinch flats and extends the tube’s lifespan.

Also check:

• The condition of the rim tape

• That no foreign objects are inside the bike tire

• That the tube is properly seated during installation

Conclusion

The 20x1.95 inner tube is a must-have for keeping your bike wheel in top shape. A properly fitted, high-quality tube will give you a smoother ride, better grip, and solid protection against flats. Whether you’re into BMX or equipping a child’s bike, go for quality and make sure it fits your bike tire perfectly.
