Your entitlement will be shown on the back of your photocard licence; you're looking for category A1.
From memory, I think you had to apply separately for A1 provisional entitlement and it was only valid for 2 years, to give time to pass the full bike test - or does a full car licence give automatic A1 provisional entitlement? They keep changing the rules!
Can't check my own licence because I've got a full bike licence which stays valid until your 70th birthday (to save User posting, it's actually the eve of your 70th birthday

).
