My little lad Eoin aged 6, has been to the Adrenalin club at Brands Hatch, really well run.
  A guy called Chris, a racer himself, is so good with the children, I even brought she who must be obeyed last time and he managed to put her mind at rest about falling off etc. 
 it's £50.00 to cover ACU insurance bike hire and helmet and protection for 2 hours  
 hope it helps
