never ever ride in the door zone: that's the area within a metre of parked cars. Doors tend to fly open. Very nasty.

never ever ride up on the inside of moving vehicles near a junction. They'll turn left across you

if you're overtaking vehicles watch out for U turners

ensure your bike works...good brakes etc etc

don't jump red lights

be nice

obey traffic rules

read John Franklin's Cycle Craft and the Highway Code

don't wear headphones/earpieces. You need all your senses all the time

always behave predictably

hand-signal when turning

don't ride in the gutter...because...

assertive cycling is the key. You are traffic. Behave like it and don't hesitate to ride in the middle of the lane when necessary

always have lights at night

helmet? I don't. It's a matter of personnel choice

make eye contact with drivers of other vehicles at junctions/side roads etc

in potentially dodgy areas - like lonely canal towpaths at night, you'll feel safer on a bike. Debateable. Be careful out there

be constantly aware of what's around you

if it doesn't feel right and natural, something's wrong. Get advice

above all, love it and spread the word.
