  • Works on my Granddaughter NIU
Made of decent quality and so far it's working great and holding air.
Reviewed in the United States on June 20, 2026 by Michael OBrien

  • Perfect for NIU KQi 100P
Got a flat in the rear tire from jumping rough pavement slab, and hitting the ground a bit hard causing a pinch puncture. Part of the problem was under inflated tires. I have only used one of these inner tubes so far, and it was my first electric scooter inner tube replacement. Pros: Excellent thickness, no leaks after a couple of months, compatible with NIU 100P, great fit and finish, and good value for money. Cons: none so far. ... show more

  • Easy to install
It's been almost two weeks since I replaced the tube, and the scooter hasn't had any issues. I'm hoping it lasts longer, but my advice to any scooter owner is to get a tubeless tire for peace of mind.

  • Low quality. Popped under heat while riding on 80 degree day.
Popped while 14 year old daughter was riding her scooter after just 1 month. It takes a lot of effort, and tire levers or spoons (which these don't come with) to change these out. I'm not happy. Do not buy for GoTrax XR Pro.
