I raced bicycles when I was younger. I enjoyed it greatly. The tactics of the different races fascinated me. I was actually a terrible rider. Whether on the velodrome, a closed course criterium, open road race or time trial, I was not very good, terrible in fact. My only bright spot was mountain climbing. Steep hills I could climb in a barely adequate fashion.
I do miss the race tactics though, so I look for games that let me re-live the racing vicariously through plastic or cardboard figures. I found quite a few games that are about bicycle racing here on BGG. Most are simple roll and move type games. Quite a few are from very small publishers, some from long ago, making actually seeing most of these games impossible. I know A LOT of games published are not even listed here on BGG. Maybe people will enter any they have that are not here, as I, and apparently many others, am very interested in games on bicycle racing!
I have also included some bicycle touring games as some do have a race element. Mostly, the games here have bicycles in them!

Anki Toner from Barcelona, Spain and Ludo Nauws from Belgium are responsible for many of the pictures and descriptions of obscure cycling games that are posted here on BGG. A big thanks to both of them!

Edit: Searched BGG for more game and added them Sept. 2007 and again in November 2007.
Edit: Added many games May, 2009
