Wanted - 'Standard' Men's MTB with hydro brakes and lockout forks (Size L or XL)

I'm looking for a Men's MTB for my son, who's now 6' 1". He's outgrown his current MTB and simply needs something standard (i.e. doesn't have trick bits that attract attention) to ride to school for now until next year. He'll be getting a decent ride for his Birthday later next year. The only requisites are hydraulic brakes and lockout forks, and size L or XL, to suit a tall kid.

I'm in Cheshire and can drive a bit to collect. Thanks.
