[Closed] hardtail for around £500-£600

Good evening,
Im early 50s just been diagnosed with being at risk of being a diabetic in the future due to other medical conditions and want a hardtail to cycle to work and to go on some easyish trails. I have a Vitus dee29 which I love but wish to spend a little more (without going over the top price wise) and would like gears and front shocks/suspension. As Im tall and slim I favour the larger frame size too
Ideally I would like a 29er as Ive got used to this wheel size.
Many thanks for all your help
