A playable demo for Trials Evolution: Gold Edition is now available, providing a test ride of the Windows edition of RedLynx's motorcycle racing game. Steam offers a version of the demo on their service, and there's a downloadable edition available on Gamer's Hell. For those who enjoy the demo, they announce the full game will go on sale on Steam on May 9th for 25% off, so buying it before then would be imprudent.
