There’s quite a lot about that which I like but there are a few curious design decisions, notably the very slack seat angle and the narrow low volume tyres. With the pressfit BB and stay yokes there should be plenty of room for big tyres but it isn’t clear on the drawings. I don’t get why it has quite so much fork travel either, 165mm is a lot on a full-sus, let alone a hardtail!
I started designing my own hardtail last year but before the build got started Bird launched their new Zero AM and I realised an angleset and shorter fork would make it very close to my design:
My own design had 10mm more chainstay length, 5mm higher BB, 5mm more reach, 10mm less fork travel and the angles were within 0.3 deg. Having ridden 500 miles on it, I’ve concluded I prefer the shorter chainstays of the Zero AM, the shorter reach and the greater fork travel (130mm) but I’d rather the BB were 5-10mm higher.
My summer rear tyre is a Minion SS 27.5×2.3 Exo Silkworm, front a Minion DHR2 27.5×2.3 Exo 3C.
