Polygon is well known for manufacturing not only their own brand but also producing bikes for a multitude of other brands. In doing so they are able to draw on all the best concepts and technologies and put them into their own Polygon range.

This year Polygon has upgraded the Premier 5 frame to a lighter weight, hydroformed Alutech Sport XC frame which was also used on the previous year higher spec Xtrada models. A new curved and hydroformed aluminium top tube reduces weight and gives the bike a more refined presence. The gear cables are now routed inside the frame and feature end-to-end outer cables, this makes the Premier frame more appealing to the eye and also dramatically reduces the servicing period as gear cables are protected from the elements. Additionally, the frame features rack mounts which allow you to easily attach racks or a baby seat. 

The Premier 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 Suntour XCM fork features oversized stanchions and 120mm of damped travel. When the trail or road smooths out, there is also a new Hydraulic Speed Lockout lever to stop the fork from compressing and ensures the bike can also perform as an efficient commuter.

Beautifully balancing performance and durability, the Polygon Premier 5 uses a Shimano Acera drivetrain to deliver 27 Speeds, capable of tackling even the steepest of hills. A direct mount derailleur provides added strength protecting the derailleur from bending if hit by a rock or stump on the trail. Upgraded Tektro Hydraulic disc brakes provide industry-leading braking power, especially in wet and muddy conditions. Completing this bike, the Premier 5 rolls on a set of alloy double wall rims with premium branded Shimano alloy hubs.

It’s this combination of all of these durable components that ensure the bike remains a true performer for years to come, whether it’s on rough trails, or for those trips down to park or beach.

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

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.
