For those interested, I promised one my riding buddy I would make the time when at Eurobike to hunt out the Litville stand & take a tape measure to check the BB height.
Luckily, they had a large 301 with 160mm plates & a 160mm Fox 34 on it along with a set of 650B wheels on the stand.
The BB measured ~357mm on it. The tyres were a Schwalbe Magic Mary 2.3 front & a Rock Razor 2.3 rear (which incidentally are MASSIVE compared to the First Ride samples of the same tyres I have been using. They utterly dwarf a Hans D by comparison)).
Considering the size of the tyres, and that being a near on real life measurement, that's actually pretty low compared to other actual measurements in my experience, rather than some of the make believes you see.
Bear in mind if you run it with 140 plates, it's an extra 10mm lower again.
Looking at them as well, it's a nicely thought out design, with a lot of good features. The suspension looks a bit odd under compression, but having known nothing about them, it looks like a cool bike.
