Another vote for Poole/Bournemouth area.
Good enough riding (Purbecks etc), loads of people to ride with (40 / 50 on mid week evenings) if that takes your fancy, cream teas a plenty.
Southampton 30mins, Portsmouth 45mins, London hour and a half (train 2 hours), nice weather, beaches, AFC Bournemouth, ice creams, ferries to France, airport, excellent bike shops.
Good schools, not 'that' expensive for housing (sandbanks excluding) and it's still in the south, so no interpretor needed.
