EXTRA INFORMATION
Size
18x2.50 inner tube, ETRTO 64-355: 64 mm wide, 355 mm rim diameter. This size fits 18 inch electric unicycles, notably the KingSong KS-18 and the Gotway MSuper.
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.
