Overview

Is the EVO 20" Schrader Tube the Right Fit for Your Ride?

The EVO 20" Bicycle Tube covers the most common wheel size in kids' and youth cycling, 20-inch wheels running 1.5 to 1.75-inch tires. The 48mm Schrader valve adds extra stem length for easier pump access on bikes with aero or deeper rims, while the standard Schrader interface means any floor pump or gas station compressor gets you sorted without adapters. Whether it's a BMX, a youth road bike, or a first mountain bike, this tube covers the spec.

EVO tubes are built to consistent wall tolerances, so installation is clean and the tube seats without folding or pinching under the bead. Keep one in your kit bag and one on the shelf at home . 20-inch flats are a matter of when, not if, and being stocked means a flat stays a five-minute fix. Compatible with 20 x 1.5 to 1.75-inch tires with Schrader valve rims, sold individually.

What bikes use a 20-inch tube?

20-inch wheels are common on BMX bikes, youth mountain and road bikes, and some folding bikes. Check your tire sidewall for the size marking before purchasing.

Why does this tube have a 48mm valve instead of 35mm?

The 48mm stem length provides better pump access on bikes with aero rims or narrower valve cutouts. It works fine on standard rims as well.

Can I use any pump with a Schrader valve?

Yes. Schrader valves work with any floor pump, hand pump, or gas station air compressor that has a Schrader fitting. No adapter needed.
