My frame broke on the downtubes under the steering. No warning. It almost looked like it got pipe cuttered, just below the steering kingpin. The break was clean and shiny. I was only doing about ten mph. If I was going faster, I would have broken bones. I had the bike about eight years, but I never had a minibike, a bicycle, or a full motorcycle do that. I had about seven minis, four bicycles, and two motorcycles.
