The new and improved 2018 Polygon Path i8 is your ultimate city / street bike. It is fast, stylish and a functional partner-in-crime for all your urban adventures.

The standout feature is the Shimano Nexus 8 internal rear hub. “Sealed for life” unit together with the carbon belt drive means that the drivetrain is almost maintenance free. The belt drive is the same that is used in a car’s timing belt – it doesn’t require lube and will easily outlast a typical chain with a life expectancy of over 10 years. 

The hub also has additional advantages including an impressive 302% gear range which is about the same range as a typical mountain bike, which is a tremendous help for hillier roads. With the gears being internal, you will also avoid having broken or damaged derailleurs stopping your ride prematurely.  The sophisticated unit also allows you to change gears without pedalling – very useful if you have forgotten to down shift whilst coming to a set of lights.

Path i8 also now comes fully equipped with premium spec Shimano M365 hydraulic disc brakes complimented with an Entity expert cockpit – they have been carefully chosen to match the high level components featured on the bike.

Polygon have also made refinements to the bottom bracket on the i8, this is an eccentric bottom bracket that is used to install and tension the belt.  This has been totally redesigned so that it will not slip or move unload load.

To finish off the Polygon Path i8, a trustworthy set of Araya Deep V rims will endure the everyday commuting punishment you throw at them. Polygon handpicked the Schwalbe Spicer tyres for their puncture protection and extreme range

The Polygon Path i8 is simply the most; low maintenance, smoothest and most enjoyable bikes in the Polygon range

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.

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.
