Review on 🛴 Aibiku Upgraded 8.5-Inch Thick Inner Tubes - Compatible with Xiaomi M365 / Gotrax Electric Scooter - Inflated Spare Tire 8 1/2 x 2 (Pair) by Dave Cavazos

I haven't installed any of these yet but upon visual and tactile examination they seem to be the same quality and about the same thickness as the Xiaomi M365 factory tubes. I wouldn't go so far as to say "thickening" is inaccurate as the Xiaomi tubes are also significantly thicker than other scooters I've used. The valves work and have removable cores, but I would clean the insides of the valves. a little and possibly apply some sealant to the threads to ensure maximum security.
