I like this one because its been my avatar for years, and its usable for years as you cant reaaly tell what year/model of bike it is so wont age (of course we all know it an SD)

This one is cool, but not sure if my helmet would be too high on the frame to wrap it around the canvas:

Then there is this one, I like because no one else is on the track, almost knee down, colourful and flowing:

So please vote and will post will pic once I have it on my wall.
Might get it done in black and white.....hmmmm
