Summary
The Polygon Siskiu trail bike series is praised for its modern geometry, competitive pricing, and improved specifications, making it a strong contender in the affordable trail bike market. Reviews highlight its effective rear suspension and trail-ready handling, though some models suffer from subpar fork performance and component limitations. The Siskiu stands out for its value, offering features like dropper posts and quality drivetrains at lower price points than many competitors.
Modern, well-considered geometry
Competitive pricing with improved specifications
Effective rear suspension with good progression
Dropper post included at affordable price points
Quality drivetrains and brakes in higher models
Subpar fork performance in some models
Component choices limit the bike's potential
Uncomfortable stock saddle and grips
Limited water bottle mounting in some frames
Heavy weight with 29in wheels in certain builds
The bike seemed to offer more performance than the price would imply, and it seemed like a platform worthy of future upgrades.
Putting together well-appointed bikes for less money than its big-name competitors is a game that Polygon plays exceedingly well.
The potential that's unrealized with this bike is both impressive at the price and depressing at the same time.

Possibly the best $2,500 bike we've ever ridden.
Fully capable, modern trail bike geometry
Excellent parts spec for the price
Internal cable routing
Resin-only brake rotors create weak braking
Suspension platform isn't very sophisticated

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 …
Smart component choices.
Great fork and shock.
Geometry that most riders will feel instantly comfortable with.
The price, obviously!
Short travel dropper post.
No water bottle mount.
