well we have these things aswell.. but if i peddle my ass off.. i can reach something below 40,.. you got hills.. (you little &^%%&*erds..) so it is plausible.. ? i say props..
That's like 54 mph (Or something around there), pretty much highway speed. Just under 40 is do-able, but 86 I'm not so sure about. Was the go-pro on your head rolling at the time?
I've gone no hands at that speed on a road bike. His HA is slack and his BB is low. It's moderately stable at that speed.
I don't know what else to tell you. The evidence is right there.
I'm not saying that riding with no hands at high speed is difficult, I'm just entertaining the idea that there could have been a car behind him.
I don't think it's completely impossible to achieve this speed, but we are on the internet after all...
