Hi, I am looking to pick up a beginners mountain bike, predominantly for casual cycling on roads, in woodlands and along footpaths etc. My preferred budget is around £300 but I could stretch to £400 depending whether the extra money would be worth it. I'm really not looking for anything flashy at all. I'm 23, around 5"7 and 14 stone. I've found a few online - see links below. Are these decent beginner bikes? Struggling to decide as I know nothing about bikes so don't really understand the specs at all. https://www.gooutdoors.co.uk/calibre-saw-mountain-bike-p414114 https://www.gooutdoors.co.uk/calibre-slab-mountain-bike-p446506 https://www.cyclerepublic.com/carrera-vulcan-27-5-mens-mountain-bike-2019.html Any help would be much appreciated - feel free to post suggestions etc!
