  • Terrible, awful product
This is a terrible product. Stay away and order from someone else. The order comes with x2 tube's. The 1st one didn't even last as long as it took to put the tire back onto the bike and it was already leaking air. The 2nd one lasted long enough for my 10 yr old to ride his bike to the end of the street and back to the house and it was flat. There's nothing heavy duty about them, they're just basic tube's. I'm more about of the fact my son is out of a bike for about a week because now I have to buy another tube, wait for it and reinstall. ... show more

  • Cheap and horrible fit.
These inner tubes are absolutely horrible to say the least!!!. It didn't pop or have a leak as others described. My problem is they just don't fit right. I know my bike tires are 16" and I bought that size before from another manufacturer and they worked perfectly. With these I feel like I'm on a train riding my scooter because it seems like I have a bubble in my tire. I will never buy this brand again! ... show more
