Polygon Siskiu D8 - Flow MTB Review

The Siksiu D8 is Polygon’s aluminium frame 27.5″ wheel dually with 120mm of suspension travel, purchased online from Bicycles Online and shipped to your door.

Buying a bike from a website isn’t a new thing, and it sure does comes with the typical drawbacks, but Bicycles Online do their best to ensure the process is as simple and easy as possible. There are systems in place like their 14 day returns policy, assembly video tutorials, sizing guide and the option of a $99 Pro Build where the bike is unpacked built at the Bicycles Online workshop in Sydney by a mechanic, then tested and tuned before re-packing for shipping.


Polygon’s huge dual suspension catalogue is full of weird and wonderful looking bikes using advanced suspension designs and carbon frames (like this wild one), but the Siskiu keeps it pretty simple with a classic single-pivot suspension design and an aluminium frame.

The big changes to the frame for 2016 from the previous model is the hydro-formed (call it curvy) tube shapes, wider 142mm dropouts to keep up with current wheel standards and routing the gear cables internally through the frame.

The whole bike weighs only 13.3kg, we think that’s pretty good!

Riding the Siskiu was more than just a case of ‘getting what you pay for’, it showed us how far mountain bike development has come and the ‘technology trickle down effect’ is certainly working.

Polygon’s are sold online, so unless you’re able to try before you by at the Bicycles Online headquarters in Sydney’s north you’ll face the challenges of online shopping, but that’s also why this bike is such killer value.

In the end we enjoyed this bike with such solid performance and reliability from the components fitted to a sturdy and well-thought-out frame, we’d take a Siskiu D8 over a hardtail any day.
