Inner tube 10x2.125 with right valve

Size

10x2.125 inner tube, inner diameter 6.5 inches (165 mm). This size fits the Ninebot F series, the Xiaomi Mi4 and machines with the same fitment. The rubber adapts to a range of widths around 2.125 inches.

Straight valve

The valve is perpendicular to the rim, with no bend. This is the simplest and most common fitment: it works whenever nothing obstructs access to the valve — no brake disc or motor facing it, and enough clearance under the mudguard.

On rims where access is restricted, an angled valve is required. Check the angle of the original tube before ordering: this is the leading cause of error on this product family.

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.
