Summary
The Polygon Xquarone stands out in the enduro category with its unique R3ACT 2Play suspension system, offering impressive traction, efficiency, and composure in rough terrain. While it excels in pedaling and descending, its unconventional design and conservative geometry may not suit all riders. The bike is praised for its ability to carry speed through challenging sections and its surprising climbing efficiency, despite some limitations in steep, technical trails.

Watch our full video review below: Jeez it’s ugly. No, it’s not really, we promise. Pictures just don’t do this bike any favours. It’s unconventional, for sure, but when you see it in the flesh it’s far more impressive than offensive. In an era where bikes seem to settling into a couple of broader frame layouts/configurations, …
Bafflingly good as an all-rounder.
More grip and momentum than should be possible.
Climbs like a demon.
No bottle mounts.
Divisive looks.
