Maybe I should ask in the Mechanics subforum but I'll try here first.

My wife and I bought a pair of inexpensive BSO folding bikes from a local big box outlet. They were reeeally cheap so I can't complain about its value.

But a slightly annoying thing is that they don't track very well. I'm not sure if I'm explaining it right but if you don't pay attention, the bike wanders a bit when you ride it. You almost have to constantly make steering corrections to keep it in a straight line. It takes a bit of the enjoyment out of riding it. And for my wife, who isn't that great at bike riding, it's a bit disconcerting.

Is there anything that can be done about it or is that how folding bikes are?
