Valve stem for tubeless tyres with right angle. Recommend replacing when renewing tyres.
This is the common PVR type used on eScooters. Essentially if the valve is bent, like this ~90 degrees, this is the size (unless of course it's a tube!).
12mm seat for 9.5-10mm valve hole, seat is measured as described by ElectricScooterParts.com.
Notes
Older Burn-e model 35Ah (Non-2) and earlier 32Ah (2 Max) and 28Ah (2 non-Max) are fitted with this PVR50 type. Newer NAMI hubs adopt TR438 type, which has a slightly larger 12.5mm seat, they all work well on NAMI hubs as they typically have a hole of 8.8-9.5mm. Much has to do with preference for straight or bent 90 degree.
Occasionally, some owners will prefer to fit straight valves rather than original bent valves, to shield the valve stem from damage - such as in the Dragon Hurricane.
PVR60 and PVR70 are larger valves, they are a 15mm seat for 11.5mm holes which are not common on eScooters.
