Find a big carpark with a slope. Use a bike with low gearing. Point up the slope. Pedal really hard and pull up on the handlebars to get the wheely started, then ease off the power when you reach your balance point otherwise you'll have to step off the bike to prevent sore arse or head. Once you've mastere wheelies going uphill, move on to the flat, and then downhill if you're after grand-wheelie-poohbah status.

Nose wheelies are excellent fun, especially on a road bike because the brakes are arranged to make it really hard to do without necking yourself. You need a bit of speed and plenty of brakes to get the back wheel off the ground. The trick is to ease off the brakes a little at the point of no return. If you don't you'll end up with a sore arse or head. You may even lose bark or teeth. Roll for as long as possible. Extra cred points for 5 second hang time when you finally come to a stop. Mega cred points for pulling your rear wheel thru 180deg as you nonchalently stop on the packed start line of your local crit.
