heavy duty bicycle 3D model

This heavy duty bicycle has been modeled carefully ensuring the conventional standards of 4 vertices per face. There are many primitive/ objects which have been rigged to follow the main frame. The chain is rotatable by rotating the circular shape with an arrow-shape at the end. Be sure to rotate it in the appropriate axis. Likewise, the steering or so-called handle bars are rotatable. I didn't use any textures for this for I found it unnecessary. I have also made it high detail so that even the smallest and perhaps hidden parts of a bicycle haven't been left out. This is for example the braking system. It is a high poly model and thus may not appropriately match a game engine. on the contrary, this would be very cool for animation, visual effects or other such uses of 3D models that aim at achieving high quality realistic looking works.
