Ubisoft has released a free demo version of RedLynx's racing-platformer, Trials Evolution: Gold Edition, via Steam in advance of an upcoming sale later this week.

The sale, which starts May 9 and continues through May 13, will drop the price of Trials Evolution: Gold Edition from $19.99 to $14.99, or from £15.99 to £11.99 for buyers in Europe.

Trials Evolution: Gold Edition includes all content from 2012's Xbox Live Arcade release Trials Evolution, along with all tracks from its predecessor Trials HD. The game also includes an in-game track editor and level-sharing functionality, giving players access to a treasure trove of virtual injuries and other motorcycle-related mishaps.
