Flow Mountain Bike
Tested: Polygon Siskiu N9 2019

Nov 2018

What makes this bike special? It’s not just the price, though at $3699, this one is hard to beat. Even when stacked up against other direct-to-the-consumer brands like YT, this bike holds its own in sheer value for money terms. The frameset is far from revolutionary, all aluminium, with a simple faux-bar suspension system. But …

Highs
  • Smart component choices.

  • Great fork and shock.

  • Geometry that most riders will feel instantly comfortable with.

  • The price, obviously!

Lows
  • Short travel dropper post.

  • No water bottle mount.

Polygon Siskiu D5 review - MBR

Aug 2018 · Alan Muldoon

Yes, the Polygon Siskiu D5 frame is top-notch but the parts spec is lacking. If it was £750 it'd be a steal but it's outclassed by other £1k full sussers.

Highs
  • Super sleek frame design.

Lows
  • No rebound adjustment on shock.

Nov 2017

Joining a number of manufacturers who have already offered different wheel sizes for the same model, Polygon is introducing the new Siskiu …
