In Australia, which is filled with outback areas striped with single-track, owning a mountain bike has become more of a right of passage rather than a recreational activity. The best mountain bikes are designed for off-road conditions — meaning they have bigger component parts in order to provide better adhesive friction when riding through steep slopes or trudging on uneven terrain.

From mossy Tasmanian forests to the single-track at Mount Kosciuszko, mountain bikes are one of the best ways to enjoy the best that Australia has to offer.

 If you’re new to the sport, here are a few reasons why you should invest in your own mountain bike:

1. Mountain bikes have more pedal power

The best mountain bikes feature efficient designs that push your pedaling into a more forward motion. This is particularly important when you’re going downhill, so you can get as much forward motion without putting too much stress on your legs.

2. Mountain bikes have more stability

Because mountain bikes have larger components, they allow for more stability in order to handle rougher terrain. They also come with suspension units that do an excellent job at absorbing shock, leading to less bumpy rides.

 3. Mountain bikes have more traction

Because both wheels absorb bump force, your tires stay more firmly planted on trail and provide better traction especially on slippery surfaces.

 4. Mountain bikes are easy to control

More traction also means you have better control over the mountain bike. Since the tires don’t lose contact with the trail easily, you can dart left and right or stop quicker.


Choosing the best mountain bike for your needs is vital if you want to get the most out of your outdoor adventure.

We’re here to take some of the stress out of buying a new mountain bike. Here are are a few factors to consider when making your choice:

  1. Type of Mountain Bikes
  • Rigid Mountain Bikes — These bikes have no suspension on the front fork or rear. They are great for riding on pavements are recommended for beginners.
  • Hardtail Mountain Bikes — These bikes have suspension shocks on the front fork, but not the rear. They are lightweight and affordable, making them great for cross country riding.
  • Full-suspension Bikes — These bikes have suspension on both the front and rear, making it more comfortable. They are generally heavier and more expensive, and are typically used for more technical trails.


Hard Tail


  1. Wheel Size

 The standard wheel size is 26 inches, but lots of biking enthusiasts prefer larger sizes, ranging up to 29 inches. But for beginners, a good entry level wheel size should be somewhere in the middle — 27.5 inches. These have the advantage of carrying momentum better and providing more traction.

  1. Bike Frame

There are many options when it comes to bike frames, the most popular being: aluminium, steel, and carbon fibre.

As a general rule, aluminium is the ideal choice because it offers a good balance of strength, weight, and cost. It also has a reasonable amount of shock-absorbing power especially for hardtail bikes. Carbon fibre, on the other hand, gives you more control over the bike but lacks durability.
