I bought this mountain bike during COVID for $1800 (plus professional assembly and tubeless tire upgrade for another ~$500) but then I got into grad school right afterwards and basically never rode it. I've ridden it fewer than 10 times - its basically new.
Polygon has grown in the MTB scene in the past 3-5 years and took advantage of supply chain challenges during COVID since they are produced in Indonesia. Good quality at more reasonable prices than the dominant brands. The RockShox are great! I upgraded the pedals (Giant studded pedals) and tires (tubeless Maxxis). This bike is perfect for a beginner or intermediate level.
I am 6'3'' - bike is sized XL (height 6'3"-6'7")
