Best overall mountain bike: Norco Fluid FS-1
- Specs exceed price point
- Quality frame
- Brakes are lacking
- Not the lightest
Price (RRP): $3,399
Why we chose it
The best overall mountain bike is the Fluid FS-1 from Canadian brand Norco, which is part of its enthusiast-level product line-up.
With a dropper seat post and tubeless-ready wheels as standard, it's easy to see why customers love this bike. There's a choice of 29" or 27.5" rolling stock and a 1 x drivetrain fitted too.
The alloy frame provides an impressive 130mm RockShox Revelation RC fork at the front and 120mm of travel at the rear controlled by a RockShox Deluxe R shock.
SRAM, known for its high quality and innovative manufacturing, provides the NX Eagle 12-speed gear set with a large ratio 10-50 cassette which ensures smooth transitions. The Maxxis Forecaster 2.6" 27.5" tyres on WTB STP i29 rims with Novatec hubs (thru-axle) provides a reliable ride. To finish it off the SRAM Guide T hydraulic disc brakes really do complete the all-round excellent package.
Best mountain bike under $2,000: 2021 Marin San Quentin 1
- Great trail geometry
- Easy to build
- No seat dropper
- One customer noted it needed a few upgrades
Price (RRP): $1,399Buy at Bicycles Online
Why we chose it
With an average rating of 4.8 out of 5 from 10 reviews on bicyclesonline.com.au, the best mountain bike under $2,000 is the 2021 Marin San Quentin 1.
This bike features a Series 2 aluminium frame, tapered head tubes, 3D forged dropouts and semi-internal cable routing, which gives it a sleek look.
Specifications highlights include SR Suntour XCM32 Boost 15x110mm Spacing, 120mm Travel, MicroShift Advent and Wide-Range 9-Speed Drivetrain. There are wide 29mm Rims with 2.6" tyres and Tektro M275 Hydraulic discs.
The slack head tube and seat tube are angled for both up and downhill riding. This puts the rider's weight between the wheels for impressive climbing and riding on flat surfaces. The slack front end and short rear centre also help to pull you through the rough descents and corners.
Best mountain bike under $1,000: Reid Argon 29
- Good value
- Comfortable ride
- Some customers noted the brand provides poor customer service
- Riser handlebar is not ideal
Price (RRP): $899.99
Why we chose it
The Reid Argon 29 comes in comfortably under the $1,000 budget but stacks up impressively for the price. The Reid Argon 29 stands up to other more expensive bikes and given the price you truly get your money's worth.
With a sturdy aluminium frame, it comes with a reliable Suntour XCM double crankset alongside the 9-speed Shimano Alivio groupset to provide enough gears to see you through any terrain. The wheels are 29" double-walled aluminium on 2.25in tyres.
Reid sells directly to the consumer, which means if you order a bike you can expect to complete some self-assembly, but this means that they're able to keep costs down and pass that saving onto the consumer. They are also available assembled directly from one of their retail outlets.
Best mountain bike under $500: Giant ATX 3
- Integrated mounts make it easy to add racks or fenders
- Powerful brakes deliver confident handling in all types of weather
- The hybrid tires are not ideal for single track riding
- Quick-release seatpost collar is a theft hazard for city riding
Price (RRP): $499Buy at eBay
Why we chose it
The best mountain bike under $500 is the Giant ATX 3. This stylish ride is the ideal entry mountain bike for use either on the road in the woods.
While there are full suspension mountain bikes for under $500 they are heavy and the shocks are not ideal for any real off-road use. If you're looking for value, you'd be hard pushed.
Upright positioning may make this less attractive for the seasoned rider but it comes with a huge wheel diameter to the size of frame, made from high-quality Giant ALUXX aluminum. The material is also very light but really strong, making the bike very durable.
Available in two different wheel sizes and every ATX features a quality Shimano drivetrain and a 90mm SR Suntour suspension fork to add control when heading off-road.
The ATX 3 disc comes with a flat handlebar, a typical feature of a mountain bike, which helps riders climb hills easily and ride confidently through narrow corridors and paths.
Best hardtail mountain bike: Giant Talon 2
- Good value for money
- Ideal as a first mountain bike purchase
- One critic said they prefer a tyre with a more aggressive tread pattern
- One review noted the fork felt harsh at speed
Price (RRP): $999Buy at eBay
Why we chose it
The best hardtail mountain bike is the Giant Talon 2. It is one of the best selling entry-level hardtail mountain bikes available in Australia when you consider what you get for your money.
An overhaul in 2017 included pretty generous specification additions and a welcome weight reduction. The Talon range has continued to grow in popularity since then. At once a great all-terrain commuter and fitness bike, as well as an ideal choice for those looking to experiment with racing.
For 2020, the talon 2 is kitted out with a 9-speed Shimano groupset paired with a double crankset and a wide range 11-36T cassette. The wide gear range supports a variety of terrains. An uncommon bonus is the tubeless-ready rims, which allows for lower tyre pressure to be used. This reduces the risk of puncture and increases traction. Completing the package is an SR Suntour XCM fork with 100m of travel and hydraulic lockout. Customer reviews noted the internal cable routing which gives the bike a very clean and sleek overall look.
Best dual suspension mountain bike: Giant Trance 3
- Packed with features
- Great suspension
- Narrow bar and long stem
- One reviewer noted the slack effective seat angle
Price (RRP): $3,199Buy at eBay
Why we chose it
The best dual suspension mountain bike is the Giant Trance 3. This modern trail bike is capable of handling difficult trails just as smoothly as a fast flowing singletrack.
The Giant Trance 3 features a huge 150, of suspension travel at the front and an impressive 140mm at the rear. The alloy frame, one of the reasons customers love the brand, is combined with a thru-axle-equipped Suntour Aion 35 RC fork and a RockShox Deluxe R shock.
Rolling stock comes in the form of proprietary 27.5in AM alloy wheels, complimented by the tubeless Maxxis High Roller II tyres. Shimano Deore 1x10-speed shifting, a PraxisWorks 1 x crankset and Shimano M365 hydraulic disc brakes round off the main package. A bonus treat which customers love about this model is that it comes with Giants Contact Switch dropper seatpost as standard.
