Electric Bike Inner Tube 26x4.0 Schrader Valve Premium Quality

Electric Bike Inner Tube 26x4.0 with Schrader Valve

This inner tube is sized for 26x4.0 tyres and fitted with a Schrader valve. The declared wheel diameter is 559 mm, corresponding to 26 inches — the standard used on many electric bikes and fat-tyre builds. The photos form part of the description; please review them alongside the specifications below.

Why this inner tube is specified for 26x4.0 fitments

Fat-tyre electric bikes run at lower pressures than standard city machines, and the inner tube has to match both the tyre section and the rim diameter exactly. Here the numbers are explicit: 26x4.0 tyre size, Schrader valve, and a 559 mm rim seat diameter. Confirm the marking on your current tyre sidewall before ordering — 559 mm and 26" are the same interface, stated two ways.

• Tyre size: 26x4.0
• Valve type: Schrader
• Wheel diameter: 559 mm — 26"
• Manufacturer part number: 0000

Matching the tube to your wheel

Two references settle the question: the tyre sidewall (26x4.0) and the rim diameter (559 mm). A Schrader valve also determines which rim drilling the tube will pass through and which pump head you will use. If you are working on a classic machine rather than an electric one, our wheels section lists rims and wheel components by diameter, and the MAVIC MODULE E 700c rim, 36H shows how a clincher rim is described when the size matters more than the badge. For a touring build in progress, the 50mm steel mudguards for 650B touring bikes pair with this kind of wheel work.
