Compatibility:This 9.5x2 inner tube is custom-engineered for Niu KQi3 Sport/Pro/Max electric scooters as a direct replacement for the original part, ensuring a seamless fit
Material & Performance: Crafted from thickened butyl rubber, it effectively absorbs impact to reduce bumpiness during rides; compared to traditional rubber inner tubes, it offers superior air retention, significantly minimizing air leaks and saving you from frequent inflation troubles
Straight Nozzle Reminder:This inner tube comes with a straight nozzle—before purchasing, please confirm that your rim has sufficient space for the nozzle to perform inflation operations smoothly
Critical Inflation Guide:For optimal performance and to prevent tire bursts, maintain pressure at 36 PSI! Inflate the inner tube to this pressure to ensure the best riding experience and extend the tube's service life
Installation & Leak-Check Instructions:During installation, slightly inflate the inner tube first, then place it into the pre-cleaned outer tire; continue inflating until the inner tube fits tightly against the outer tire wall. Before use, be sure to check for air leaks—if a leak is found, please leave a message and provide relevant proof photos so we can resolve the issue for you more effectively
