Gtfo. I've landed on one rear wheel off jumps, flipped the bike down a hill, hit trees, and other dumb things that I'm sure are WAY more of a load and stress then a ratchet strap. I've broken swing arms riding and my axle hasn't bent. When I broke both my wrist I went off a 30' cliff in 5th gear. Still have that axle today.
If you bent it strapping a bike down, you need to get into contact with the manufacturer or your extremely strong and you need to somehow make money off of that and share what kind of straps your using.
