So this is a cheapo I got for daily abuse, and unexpectedly I got three flats in the back tire in a row. Any idea why is that? I have never got frequent flats on my other (expensive) bikes.

If I want to keep this bike, would changing the back tire and tube make it better? The tires that came with it don’t seem to be very quality.
Tube might need to be replace?
Does the wheel have a tube liner to protect it from the spokes?
are there any bald spots on the back tire?
You might have left the thing that flattened the tube in the tire or the rim. Determine where the flat occurs on the wheel and the tire. Check the rim for burrs around the valve stem or protruding spokes….. Is there rim tape around the rim? Check the inside of the tire for glass or metal protruding inward towards the tube.
Forgot to mention, that the first time I have replaced it with a brand new tube, and the second time I checked the tube carefully and then patched it. There’s nothing left inside the tube.
So, the first question is: ¿What cause the holes? ¿nails? ¿thorns? ¿it was damaged in the internal side of the tube or external? ¿What about the place were you bike?
When you say “in a row”, is that how the holes look in the tire or three different times?
So many questions.
I had a quick series of flats like that recently. The tube damage was always rim side, turns out the rim tape was worn out and slipping around and letting the tube expand into the spoke holes and pop. The problem can be hard to detect depending on the rim tape used, sometimes it can move back into place one you take off the tire.
If the hole is two small holes or slits within an inch of each other, it’s underinflation (pinch flats, tube pinched between road and rim). If it’s one hole on the inside it’s a spoke sticking out inside or an uncovered or rough spoke hole. If it’s on the perimeter it may be a very small wire coming through from outside–rub your finger everywhere around the inside of the tire feeling for something sharp grabbing it. If you don’t feel anything look for a piece of glass stuck in the tread on the outside that only pokes through to the inside under pressure up from the road. I think that about covers the possibilities.
Check your tires and rims and see if theres a Thorn or other sharpness in there
Also, loading up your rear crate is going to immediately crank up your probability of getting flats, especially if you do not have your tire pressure high enough (or too high!)
Get pair Conti Ride Tour. Cheap and good, not light. Problem solved.
What causes repeated, sudden, catastrophic release of air from containment within vulcanised rubber pressure vessel? (ie flat tyre)
1. Low quality, unarmoured, worn &/or soft tyres.
2. Underinflated tyres causing pinch flats.
3. Debris from previous puncture not cleared causing subsequent flats.
4. Fresh debris on the same road/surface.
5. Poor quality rim tape exposing inner tube to the spoke nipple/rim.
6. Poor repair from previous puncture.
Hope you can narrow down the cause!
Rim tape for sure.
I had an issue when I used electrical tape for rim tape and it would dry up and put holes my tubes. My bike shop friend scolded me for that. Gary I quit that shit a long time ago
could be a spoke , that is protruding into the inner tube, the type of bicycle is not the issue nor the type of tube or tire , possible under the tape that protects the tube from the spokes has a culprit, or just very bad luck
A similar problem happened to me, I decided to take my bike apart and investigate, found nothing wrong and I didn’t want to wait for a tube to arrive and wanted to support a local business as well. So I took the wheel down to a bike shop and had them replace the tube, as the guy was doing that he found a small metal piece used in car tires stuck in my wheel. It would’ve kept popping my tubes had he not found that. So run you hand along the inside of your wheel SLOWLY to see if you find anything stuck in it
