Why can't I animate more than one part of object in Unity Animation?

Hi,

I am trying to make a human model walk/pedal a bike, looking at Unity’s Animation module to do this. I have a model and avatar / rig assigned to it but is disabled/enabled, makes no difference to my problem it seems.

I see Unity 3D Tutorial Part 15: Basic Animation - YouTube which shows how someone was able to move an avatar , moving several parts of the body in the Animation window, which is what I want to be able to so… why can’t I do this?

I have created small video to show what I am seeing, see video:

You’ll see I am able to animate one part of the body but not others? I have Unity 4.3.4

Why can’t I animate more than one part of object in Unity Animation?
I hope someone could tell if/what I am doing wrong.

I wouldn’t even recommend animating anything in Unity. Well the basic stuff like moving cube and all that, yeah. But if you want to make a character walk animation, you wont be able to make it in Unity. What I recommend is Blender or if you can get a better, advanced one: Maya or 3Ds Max.
