I've had mine spin out of my hands but I was doing about 25-30mph and hit a rock on the side of the trail with the side of the tire. took a chunk out of the tire, I wouldn't expect anything different though. normal riding it's been fine for me can get a little jerky over really rough stuff but nothing out of the ordinary. I usually don't have a death grip on the wheel so going slow over really rough stuff sometimes the wheel will catch a rock and spin to the lock but only because I wasn't holding the wheel tight.
