Due to customer feedback, the latest production run of the Polygon Xtrada 5 now comes with black forks as per product images. 

“Synergy” is defined as being when the whole is greater than the sum of the parts.  Never has this been more evident than with the Polygon Xtrada 5, certainly the parts, individually, are well designed, however, when grouped together as on the Xtrada 5 they produce something remarkable. The result is a smooth rolling package combined with effortless class and good looks. It’s a bike that will be just as credible on the mountain bike trail, as it will be commuting in the city. The outcome is much greater than the simple arithmetic summation of the parts.

The Xtrada 5 is built around a lightweight, hydroformed Alutech Sport XC frame. A new curved and hydroformed aluminium top tube reduces weight and gives the bike a more refined presence. The frame comes internally routed, which provides cleaner lines to the bike and also reduces the chances of any cables getting snagged on trees or rocks while riding. Polygon is so confident in the performance of this frame that it has a lifetime warranty.

The Xtrada series utilises Polygon's new Wheel Fit Size System whereby each frame size is paired with the wheel size that best fits the rider and sets them up for optimal efficiency and power transfer. We pair 29˝ wheels with 18.5˝ and larger bikes, and more proportional, better-fitting 27.5˝ wheels for 17.5˝ and smaller bikes.

The Xtrada 5.0 is spec'd with the Shimano Alivio M4000, 18-speed groupset. Much of its technology has been trickled down from Shimano's premium high-end groupsets. Small details like the new direct mount rear derailleur, RapidFire Plus, 2 Way release and Octalink bottom bracket unit were once exclusive to XT and SLX and yet now are available on the Alivio groupset. Polygon has opted for the 2 x 9-speed setup this year based on customer feedback from the previous year model. Using a double chainring as opposed to triple chainring significantly reduces cross chaining and also means less maintenance and smoother shifting. A new wider 11-36T cassette on the rear also means there is minimal difference in gear ratio. 

The bike comes equipped with a 120mm travel SR Suntour XCM suspension fork (with a hydraulic lockout ) to give the bike greater control while descending rough terrain at high speeds. With the increased travel in the fork, the head tube and stem length have been shortened to preserve the neutral riding position that Polygons are known for. There has been no compromise on the popular handling characteristics of the bike, yet the additional travel ensures the bike is more forgiving in more technical environments. The Shimano M315 hydraulic disc brakes offer excellent modulation, fierce stopping power and yet are simple to service.

The Deli Trax tyres offer oodles of grip off road with its side knobs and a fast rolling center track. Araya double wall alloy rims laced onto genuine Shimano alloy hubs complete the sturdy wheelset for the bike.

This blend of durability and performance has made the Xtrada 5 one of our most popular bikes to ride and own, and one of our highest selling mountain bikes. Our large stocks combined with incredible delivery times means you can have this bike within just a couple of days.

We understand how important shipping is once you click "buy now", that's why we have the following policies

Australian Warehouse

All products are in stock and ready to ship from our Sydney warehouse (with the exception of preordered bikes, which have the dispatch date illustrated)

Next day dispatch

All orders received by 5 pm AEST will usually be dispatched the following business day. If an order is placed on the weekend or public holiday, please note dispatch will usually be the next working day. For tracked shipments, please allow 12 hours for tracking to begin.

Shipping of Parts, Accessories and Apparel

Economy Shipping

There is free delivery available on all small parcels Australia wide using tracked services of Australia Post or Fastway, no minimum order value required! Estimated delivery time is 4-9 business days. 

Express Shipping

We do also offer Express Shipping for a small additional fee on parts, accessories and apparel orders. Estimated delivery time on Express Shipping is 1 to 4 business days.

Shipping of Bikes

Shipping of bikes and other bulky goods is free to 85% of residences in Australia. However, some postcodes incur a surcharge starting from $29. 

Once shipped you will be issued a consignment number which can be used to track your parcel. We use Direct Freight Express for deliveries and you can track your delivery by calling 1300 347 397 or online at www.directfreight.com.au


We’re so confident that you’ll love our extensive range of bikes, that we’ll let you ride one as your own for a full 14 days and if you don’t like it, simply e-mail us at sales@bicyclesonline.com.au and we’ll pick it up from you, free of charge! Just make sure you keep the box so it can be re-used to send it back. Click here for more information. 

All of our bicycles come with a Free Pro Build valued at $99. This means that your bicycle will be pre built by our professional mechanics. For your convenience, safety and comfort all our bikes are fully assembled prior to delivery. The bike is then packaged back into a box for secure shipment.


When your bike arrives, all you have to attach is the front wheel, the handlebar and pedals, everything else has been done – the headset has been adjusted, wheels trued, pedals and seat post greased, brakes and gears calibrated, and the tyres have been pumped up (please note upon arrival, in some cases you may need to add more air to tyres).

Most companies simply sell you the bike as it comes from the factory, which will require significant know-how to get your bike on the road. Currently we are the only Australian company providing this service, and have the 14 day test ride to back it up.

All the tools required to assemble the bike are included. 

Please note, that all bicycles whether purchased online or instore, are mechanical devices and need to be serviced regularly to ensure proper functioning. New gear and brake cables, will stretch during the initial bed-in period, and will need to be adjusted after approximately 150-300km.

Whilst your new bicycle will have already gone through our Pro Build process, you will still need to complete some minor final assembly steps when you take your bicycle out of its box.

Please follow the video playlist below to correctly complete the setup of your new bike:


Assembly Time:

  • 10-15min - You have assembled bikes before
  • 15-25min - You are mechanically handy
  • 30-40min - Never assembled a bike and working with tools isn't your thing


Unboxing your bike:

Start by carefully opening the top flap to expose the contents. You will see the bike with plenty of protective packaging and next to the rear wheel, the saddle & seatpost, a small cardboard box where your pedals, tools, bell and reflectors are. If you ordered any other products with the bike, it is likely they were placed on the bottom of the box as well. Remove all the loose items before pulling the bike out of the box and gently placing it on the floor.

Keep the box and all the protective packaging found on the bike in case you choose to change frame sizes, upgrade/downgrade the bike, or return the bike for a full refund under the 14 Day Test Ride Policy.
