I don't want to sound alarmist but I'd think twice before buying a second-hand bike
Back in my cycling club days I was out for a leisurely ride with my teenage mate when SNAP his downtube broke clean as a whistle; here's a stock pic off the net to show the break in red.
The bike held together- just- and luckily we were only a couple of miles from home so he was able to limp slowly back.
Guess what? Yup it was a second-hand bike that his dad had bought him and looked good under a nice paint job which was probably covering a few metal fatigue cracks.
