If it's for less than two hours, I just have my normal breakfast (eaten about 45 mins before I leave) of muesli, bran flakes and milk, and take a banana in my back pocket, plus two water bottles.
If it's for longer, then a bowl of porridge, then my muesli, bran flakes and milk. Then I'd take a couple of bananas and some energy bars, but would call into a caf or petrol station for a cuppa and piece of cake or choccy bar.
Cycling on a full stomach isn't to be recommended.
