Inner tube 16x3.0 valve 0x90°

Size

16x3.0 inner tube. This wide size is mainly found on electric unicycles. The rubber adapts to a range of widths around 3 inches.

Beware of the two meanings of 16 inch

The 16 inch designation covers two rim diameters: 305 mm and 349 mm. Check the inner diameter of the original tube before ordering — the outer size alone is not enough to guarantee the fit.

0x90° valve

The valve is straight on its first segment and angled at 90 degrees on the second. This angle gives access to the valve from the side of the rim, where a straight valve would be hidden.

On an electric unicycle this access is often the only one possible: the wheel is enclosed between the shells and the footrests. The angle is dictated by that geometry — check the one on the original tube before ordering.

Fitting

Sold individually. Inflate the tube slightly before inserting it into the tyre to avoid folds, and make sure it is not pinched between the bead and the rim before bringing it up to pressure.
