a group of friends and a long industrial warehouse area on a weekend/evening when there is no one around. Odds are if you progress slowly you wont crash your street bike, but if you can find something cheap to use by all means. No idea how good that will actually work as a stunt bike but if all you want to learn is wheelies/stoppies personally i'd just use your street bike.
Learn to do clutch up wheelies, power up wheelies can surprise you and flip you on your ***. Clutch up wheelies come up fast but slow down once they've popped up. Always cover the rear brake and once you are able to carry a wheelie more then a few feet practice intentionally bringing them down with a little bit of rear brake (the more rear brake the faster it comes down) that way it's just a habit when you do almost go over backwards one day.
Have fun and i strongly reccomend full leathers/race boots/gauntlets in the event that you do go down.
