I have one a similar 50% off deal, bike feels very responsive and lively when climbing but at the end of the day it’s a hardtail but I can’t Say I’ve noticed it be be harsh. 29 ” wheels help I suppose.
The fork on the base model although plush for the travel is very heavy and lets down the bike a bit, the Crank in an SX but with a heavy steel BB. I’ve changed mine to an GX on a Wiggle Sale.
Possibly if you change the fork up to 130mm it may push the geometry too far back when climbing, possibly 110mm would be the limit.
Check out Guy Kes TV he’s done a project build and this should provide you with a better insight. https://www.youtube.com/watch?v=KSNOqCkzuBw
