Hi guys, thank you for the advice.
I have decided to go with a Vitus Nucleus 275 VR which came in well under £500 despite having won MBR magazine Hardtail of the year award 2017(sub£500) with a 10/10 score.
Haha I had to make my mind up soon before I was accused of being some sort of pervert. Every day when picking up my teenage daughters from school I was intently watching what bikes the dozens of lads were riding as they passed our car.
It amazes me how many teenage lads ride £750+ bikes to school.
