For the first ... I don't know how many years ... she kept getting flats in under 5 miles, no nails/thorns, glass ... sometimes the flats would come just sitting. Nothing in the tires and no protruding spokes. Eventually, I discovered the problem: both tires had a tiny pin holes in the sidewall, tube entered, tube blew. No more Kenda tires for me.
I do feel bad about not being able to ride it much, but, being bicycle poor, I only had 8 or 9 others I could ride.
