I'm 6'1 and ride an XL – it's high at the front, and not massive standover, but it feels bob on as a cross country bike. The large would be jumpier/more chuckable but this is a bike that suits shorter stems.
For reference, I ride a large Blur Classic and an Ellsworth Moment in a medium.
If you're anywhere near Preston, I've just rebuilt mine and you're more than welcome to pop over and swing a leg over it…
I was planning on selling it, but after a couple of rides, it's so much fun, I might hang on to it for a while…
