I doubt it is caused by outside object.. twice in two days and i find nothing from outside.. I suspect is factory defect where the tire's wire came off and cut the inner tube.. a very little 1 is more than enough to cause puncture as when the first time puncture, the hole on the tube is hell small.. so small that we couldnt detect where the hole until we felt it.. Will take it back to the seller and let him check since I have yet ride for more than 5 times in total.. there should be a replacement for me.. just hope they will replace 1 for me
normal road.. not dare to ride it to off road.. I couldnt find anything that possible to cause puncture from outside.. not even a cut on the tire.. so i suspect should be from inner.. the tire's wire perhaps.. that's why now try to look for good tire with puncture resistant..
y i asked, cos this is what happened to me.....
few days after i got my bike, the tyre was flat..
so i remove the inner tube, tube had a patch
who patched it?? i duno...

i got the bike frm rodalink...
then i run my fingers across the rim surface an inside of tyre which are in
contact with the inner tube, many times, could not detect anything sharp
or poking out that can cause the puncture...
then i discovered this...

inside the hollow space of the rim, were many tiny metal shavings...
i shake shake,,, it fell out from the valve hole...
i suspect during manufacturing when they drill the holes for spoke,
these are the debris from the process, and they never clean it properly,
i have to use vacuum to suck it out,, and after more than 1 year,
still can suck out more...

oso the inner tube, even tho it is schwalbe, the thickness is half of the ones
sold separately...
