So are you saying you ride fairly chunky terrain but you aren’t going to be doing big jumps and drops? Needs to be all day comfy but not fast like an xc bike?
If so there are literally loads of bikes that will do that – anything from 130-160mm travel in all likelihood.
On the lower travel end I reckon:
Bird Aether 9
Nukeproof Reactor 290
Cotic Flaremax / Jeht
Vitus Escarpe (newest one)
Santa Cruz Tallboy (newest one)
Trek Fuel EX
Sonder Evol 29er
Then maybe a bit burlier:
Bird AM9
Ibis Ripmo
Canyon Spectral
Transition Sentinel
YT Jeffsy
Santa Cruz Hightower (newest version)
Privateer 141 (quite heavy)
Commencal Meta TR (quite heavy)
I’ve had good experiences with Bird bikes – had an Aeris 145LT and an Aether 7. Wanted an Aether 9 to replace the 7 but they were out of stock at the time. Was thinking about a Nukeproof reactor 290 but they were out of stock in alloy frame sets and the carbon was too expensive. Bought a 2022 alloy Transition Sentinel and I love it. Maybe on the burly end of things for your uses at 34lbs built up fairly lightly. The carbon version has a much lighter frame but it’s £££.
Thinking the Reactor 290 could be a good option for you both in downhill ability / cost to buy. The spectral is quite a lot more travel but you might find those with good spec for the money and they seem to be well liked by owners.
