we all sooner or later get flat tires on our motorized bicycles and they are a pain to fix whether you ride an e-bike or a gas powered bicycle. something i learned today that maybe a lot of you already know however i am sure a few of you like me did not know, i could not find what kept puncturing the tube, so i checked real good with a magnifying glass and could not find anything, i turned the tire inside out so i could check from the other side, bad mistake, it did something to the bead and ruined a $50.00 schwalbe big apple tire. i guess i will mark it down as another lesson learned the hard way. word of advice is never turn a tire inside out, the damage is not repairable.
