Whether he breaks the record isn’t really the point of what he’s doing.
It’s about questioning existing thinking and having a go.
People laughed at his original pursuit bike when he rode against Chris Boardman – he beat Boardman and became world champion breaking the world record twice. Indeed he changed cycling to the point where the governing body banned his design.
He may well be bonkers but many people who have changed history have had the same thing said about them.
I think he’s brilliant – he thinks/obesses about what he does, makes his own equipment, uses his imagination and does it on his own on a very small budget.
