Are you ready to pull up stumps, take a break and embark on an off the beaten track adventure? Then the new Polygon Bend RIV Touring bike is the ride that you can depend on as you roll past beautiful vistas and secluded camping spots all over Australia and around the world.

For starters, the RIV features a super comfortable and lightweight triple butted ALX Alloy frame which was heat treated for added strength and durability, and optimized with flatmount brakes, internal routing and a tapered fork. The frame geometry sits you slightly more upright than your normal road or gravel bike, reducing stress to your lower back, neck or shoulders, with the handlebars' drops flaring outwards in an effort to reduce pressure and twist to your arms and improve comfort on long hard days on the saddle. The Polygon Bend RIV frame includes water bottle mounts, front and rear alloy racks attached to fender mounts make it easy load up and secure all of your gear.

The RIV is equipped with a durable and easy to use 1 x 11 SRAM Apex drivetrain, boosting a 11-42T cassette and a 38T chainring. This not only simplifies gear selection but offers about the same range of gears you get from a conventional 2x10 or 2x11 drivetrain ratio. The bike rolls on a set of Entity XL2 disc rims with Novatec hubs & Schwalbe Marathon Plus Tour Tyres 40c, the most sought after tyre by bikepackers worldwide who want the most effective puncture protection system on the market. Disc brakes are essential for bike touring, especially when you get caught out in a rainy day on the saddle, where rim brakes (Mountain bike V-Brakes or road Calliper Brakes) just wouldn't cut it. The Polygon Bend RIV comes equipped with SRAM Apex flatmount hydraulic disc brakes to slow you down whenever you need to take in the moment or the beautiful view from the road in all weather conditions. When it comes down to it, this is a fun and gutsy touring bike that has been well thought out with reliable and performance oriented components that won’t break the budget.

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 tools are provided with the bike.

If you are unsure of how to assemble this bike after viewing the instruction videos above, we recommend you ask for help from someone with knowledge of how to use basic hand tools.
