You can download Rider here.
Quoting dess:
it’s a motorcycle sim where you try to get your package to its destination on time without breaking any traffic laws (when cops are watching). reminds me of tokyo bus guide, but better since it involves motorcycles (and you don’t have to observe crazy bus codes). it’s a pretty nice chillout game. videogame sunsets!
There are some crazy rides to unlock if you play long enough.
EDIT: Options on the main menu, from left to right, are: records (for this playthrough), options, play and quit.
