BikerumorPolygon’s Siskiu T8 is a solid reminder of how fun even low- to mid-range bikes have become.
BikeRadarThe Siskiu N9, here, is the hardest hitting bike in the Siskiu line, with 160 or 170mm travel, and angles that have strutted right off the Enduro catwalk.

Precise handling and cornering
Excellent value

Polygon have been plugging away solidly over the past few years, building up a tidy contingent of no-nonsense, sharply priced, alloy trail bikes. We’ve reviewed plenty of them over recent times, and we’ve enjoyed watching them get better and better with each iteration, ticking all the boxes that riders demand, but not sending anyone into …
Pricing is very good!
Great suspension package.
No-nonsense design.
Seems to be a bit of internal cable rattle going on.
Both wheel sizes not available in all frame sizes.

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.
Super sleek frame design.
No rebound adjustment on shock.

It’s almost 2018 and we’re still no closer to settling on one wheel size. Don’t expect that to change any time soon, but what you can expect is new options around every corner. Joining a number of manufacturers who have already offered different wheel sizes for the same model, Polygon is introducing the new Siskiu …

Cheap, flexy fork, but the Siskiu’s poised, keen and efficiently smooth ride impresses for the price. Buy if you want a poised, smooth ride and don't mind upgrading the fork
Fast-rolling tyres and efficient yet supple rear suspension, decent frame and cockpit geometry, dropper post and thru-axle ready
Serious flex and choke from the skinny QR fork, tyres are fast but very sketchy on slippery rocks and roots
