Nitpick: That's
not drifting. But
I do not blame you for not knowing what drifting is.
Spinning the rear wheel around a turn while steering through the turn is called a
power slide.
Sliding ALL the wheels laterally around a turn is called
drifting.
Powersliding is easy; drifting is not. I haven't ever seen anyone who could drift a bicycle without crashing, at all, ever, anywhere. And I do not expect to, either.
It should be possible to drift a bicycle, since
drifting can only be performed while decelerating--so in theory you could coast down a big hill and enter a turn with enough speed to drift. I'd suggest you have an ambulance waiting at the bottom of the hill, however.
Nearly all of the videos you will find online of real, actual motorcycle drifting are professional GP racers on tracks doing it.
99% of the home-user videos of guys with motorcycles who make "drifting" videos are full of it. They are not even close.
They do not have good-enough motorcycles, they are not on good-enough road surfaces, and they are not going nearly fast enough.
Drifting takes VERY smooth pavement, VERY soft tires and fairly high speeds, 75+ MPH. You
cannot do it going slow.
This video shows it off nicely in just the first fifteen seconds: note how the FRONT wheel slides in the turn, as well as the rear wheel.
BOTH wheels leave skid marks around the turns---
