Summary
The Polygon Collosus is praised for its modern enduro geometry, providing a planted and stable ride that excels in high-speed descents and corners. It offers impressive value for money with solid build kits and efficient suspension that delivers good traction and pedal performance, though it is often noted as heavy, which can hinder playfulness and climbing agility. While the bike requires careful setup to optimize its potential, it is a capable choice for rough, gravity-focused trails.
Modern enduro geometry
Good value for money
Efficient suspension performance
Planted and stable handling
Solid build kit
Heavy weight
Requires careful setup
Limited playfulness
Draggy tires
High maintenance due to multiple pivots
It dived in and out of a snaking section of steep, supported corners in a solid, predictable manner and the dimensions felt good.
Indeed it’s a bloody good enduro bike for the money, and one that is perfectly at home riding the roughest and rowdiest gravity-fuelled descents.
Polygon once again delivered an impressive bike for the money.

The Polygon Collosus N7 is the cheapest way to purchase in new enduro mountain bike in 2023. But does that mean it's worth buying? Spoiler Alert: It's for the park rats 🐀
Extremely affordable
Relatively solid spec given the price
Great performing suspension (one you set it up correctly)
Well rounded geometry
Weight (41 lbs / 18.6 kg tested)
Weak brakes
Minimal dropper post insertion

Polygon's premier trail rig has great handling and comes in at $3k+ cheaper than rival offerings.

There's room for refinement, but it fared well against expensive competition at our trail bike Field Test.
Great value
Very capable, punches above its weight
Lots of geometry adjustments
Noticeable frame flex
Flimsy in-frame storage door (supposed to be fixed in the future)
Finishing touches aren't as refined

The latest from Polygon Bikes is the Collosus T, an aggressive new trail bike model that’s surprisingly affordable.

If you’re working with a $5k budget and seek a capable and comfortable E-Enduro rig, then the Polygon Collosus N8E is a very solid offering.

Sep 2023
Selling for well under $4,000 AUD, the Polygon Collosus N7 is one of the cheapest enduro bikes going. But is it any good?

Smooth, traction-rich suspension
Impressive pedal efficiency
Great geometry
Solid build kit
Very heavy
Draggy tyres
Noisy
Limited seatpost insertion
Lots of pivots to maintain
