Inner tubes for Model 26'' fat bike, Rocket and Hammer

Ive put over 1000 miles in under 6months. One Flat, bike still runs great, battery still holds a good charge. I set it up for fishing and kayaking.

I enjoy the bike, fun to ride. The bike went together ok, the manual was lacks many steps.
But the bike itself is a solid bike. The Hammer is a tall bike almost to tall to get over. My wife and I each has one, that’s her only complaint.

Installed the new inner tube and my tire went flat later that night coming home from work. The seal around the valve is compromised and allows air to leak through so the inner tube is no good, would like to have a replaced with a new once since I just paid 29 dollars to not even be able to use my bike for a whole day

Tubes are thick and high quality better than most.

Works as expected!
