i did it when we where 18, put her on a bike with out suspension and wide tyres and bars, in a light gear, had her ride along holding a wall a bit, then with me holding the saddle, then just let her go. once she got stright lines I had her do figure eights to pratice turns, making them smaller and smaller. all this took about two hours, in a parking lot behind a coffe shop. she was not perfect at the end of it, but was good enough she could ride, and pratice her self.
A month later she rode the 60 or so miles from her town to my house in the city, to show me her new bike.
