What do you mean by "copy?" Are you looking to re-create the animated cyclist from scratch?
The first thing would be to build the individual pieces: the cyclist and a wheel.
You should build the wheel in more of a circle so you can animate it by rotation, then scale it disproportionately in only the Y dimension to flatten it down a little. (Otherwise it will rotate from wide to tall and back.)
Once you've got the cyclist drawn, you can animate his or her motion with the Puppet tool.
