Panniers - I originally bought these to go on my first ever touring trip a few years back, but found they made huge difference for day-to-day commuting and increased the amount of biking I did. No longer did I have to balance groceries on handle bars, or arrive at the office with sweaty back from carrying a laptop in a backpack. Get one's you can clip ...

Saddle Bag - It looks quite small, but there's enough space to fit everything that I used to put in my backpack in longer rides: spare inner tube boxes, cell phone, keys, money, train travel card, tire levers and small toolset. It's so much better to ride without a backpack. Larger saddle bags are also available, sometimes mounting on rails attached to ...

Cycle Computer I'd say a cylco-computer is my best accessory. I have the Sigma 1606 with cadence addon. It allows me to guage a bunch of things, speed most obviously, but tracking my cadence, average mph, and distance have really helped me grow as a casual rider.

CamelBak (or any other backpack with a water bladder in it) - I drink a lot of water, and after missing the bottle cage a few times and running over bottles, I decided I was too clumsy to keep trying to drink from a bottle and ride at the same time.

Kickstand - simple but very useful. I used to have one when I was young but it was rubbish (bike never stayed upright) and it put me off them until recently. The one I have now is great, works with fully loaded panniers, and it means I don't need to find a wall to lean the bike against. Especially useful when doing small maintenance tasks.

Cyclaire pump It's a compact pump (comes with a small bag to attach to your top tube), and really, really fast. Changing a tube at the side of the road is bad enough without having spending ages minutes inflating it again (and tiring your arms). Now I never have to. It's not as good as a track pump, but I wouldn't want to be carrying one of those with me all ...
