These tubes best accommodate 8.5" tyres (5.5" rims) where the valve needs to extend quite some distance out from the wheel, with an sharp 90 degree tilt close to the tube end of the valve (a tall/skinny "L shape"). This valve shape is well suited on scooters with relatively large and wide motor hubs, with relatively narrow width tyres such and Inokim Light 2 series (e.g. "Super Light 2 Max" or "Light 2").
This tube accompanies the official Inokim Light 2 series genuine replacement tyre which has CST 8.5x2.00-5.5 nameplate on sidewall. This tube also suits earlier Light 2 series tyres which were Inokim branded with sidewall nameplate 8½ x 2 (50-139). The 50-139 designation was phased out with the introduction of the CST, although it is assume the specific 139mm internal diameter holds and now known as 8.5x2.00-5.5.
My Mobelity suggests this tube also supports the Light (1). Note the Inokim Light 1 is also an 8.5x2" tyre, but with 50-134 tyre size designation such as this HOTA tyre, suggesting 134mm (~5.27") rim, which quite smaller than typical 5.5" rims and 5mm smaller than the Light 2 tyre (139mm / ~5.47") The Light 1 therefore likely has a higher profile tyre. For Light 1 tyre, use Zero 8.5x2 (50-134), and for tube you can try this or source one purposed for the smaller inner diameter 50-134 (which may have nameplate prefix 8.5x2 or 8.5x2.125), or if wanting to experiment with a wider tyre try an 8½ x 3.0 / 80-139 tyre which includes an relatively light 80 gram 8½ x 2 (50-134) tube, or a ULIP 8.5x3" tyre with ULIP 8.5x2" (50-134) tube.
Inokim Light 2 series adopts 90 degree valve on rear, 45 degree on front (Boardstore), typical on single motor scooters.
Typical weight 90g (a relatively thick tube to reduce pinch punctures).
This tube is often used on makes/models often have 8.5x3" tyres such as Zero 9 and VSETT 9 series due to having a favourable valve stem shape, however the tube is "thinner" than tubes specifically designed for 8.5x3" tyres such as this tube and this one. While the shape of the valve stem is favourable on some makes/models and may have less fatigue / stress, it is assumed less resilience less when used with 8.5x3" tyres due to stress under inflation. If running 8.5x3" tyres, consider the ULIP 8.5x2" (50-134) tube.
The 8.5x3 tyres on 5.5" rims are relatively small, and with large/heavier motors the valve shape is often critical for proper fitting. eScootNow stocks alternative 90 degree bend options:
The HOTA tube adopts a similar 90 degree tilt, but with bend formed further along the stem (more distant from the tube).
The 8.5x2" tube, which has similar generous length to this tube but adopts a 60 degree tilt rather than right angle tilt.
The ULIP 8.5x2, which works well with the ULIP 8.5x3 tyre.
