Best advice I can give once you've got up to speed with the basics of riding a bike on the roads is to be constantly aware of your surroundings, try and anticipate everybody elses next move. Whether they be car/lorry/bus/taxi drivers, pedestrians, other cyclists, birds, dogs, or any other local wildlife about, always expect the unexpected.

i'm also always very weary of car doors opening when cycling past a row of parked cars, and never cycle too close to a black cab, they will break heavily at any moment. Make sure both breaks work well and some form of bell is always handy.

Enjoy it and have fun
