You don't need mountains for mountain biking but you do need off-road trails. These include easy riding on wide trails with gentle gradients through to extreme adventure trails with very steep gradients, rough and slippery surfaces and big, unavoidable obstacles.
Mountain bikers identify a number of different disciplines of the sport. Most opportunities in parks are for XC (cross-country) riding. This includes both point-to-point and loop trails with ascents and descents on existing forestry tracks, former railway formations (rail trails) or purpose-built single track (trails wide enough for just one bike). There are also an increasing number of DH (downhill) trails, which are generally in more steep and difficult terrain and require more technical cycling ability and, are one-way only.
In Western Australia we use the International Mountain Biking Association Trail Difficulty Rating System that includes an indication of the level of skills and fitness required to ride the trail, and the type of bike that you’ll need.

For cycle touring enthusiasts, the Munda Biddi Trail is a long-distance cycle touring trail that traverses a number of parks on its route between Perth and Albany. Over 1000km in length, it includes a variety of XC trail types and a number of sections of sealed and unsealed roads in between parks.
Whatever trail you ride, your bike must be in good working order and suitable for the difficulty rating of the trail. You should have access to a first aid kit, toolkit and spares and know how to fix your bike out on the trail. Lots of extra protective equipment is available. You must wear a helmet and gloves and glasses are recommended. On more difficult trails you should consider a full-face helmet and body armour.
Mountain bike clubs throughout the state run social and competitive rides, maintain existing trails and develop new ones. Details are available from WestCycle.
