Frame durability ?
Hello, does anyone have any information or experience regarding frame durability?
I mean, I’ve seen people posting about bent swing arms (tube version) and broken ones (full aluminium), apparently after just months or years of high-G manoeuvres. I’ve also seen some lightweight trikes breaking a front wheel, while more rugged/heavier trikes I've seen rear wheel failures (idk if due previous hard landings).
Since PPG foot-launch and trike frames have been on the market for many years now, has anyone collected any real-world data or statistics about frame fatigue and failures?
I’m not talking about the usual checks like loose bolts, but specifically about things like crack inspections, fatigue damage, or recommended replacement intervals — for example, is there any manufacturer or community data suggesting that a frame should be inspected or replaced after 400 hours, 600 hours, etc.?
