What I Love and Don't Love About My Polygon Siskiu D5

When I bought my 2021 Polygon Siskiu full suspension mountain bike, I chose the lower equipped D5 over the better equipped D6 and D7. Cost was a minor factor. The big issue was that I loved the red, orange, yellow and beige colors better than the other two models. I figured I might as well get the one I liked best and upgrade it.

I do love the appearance, as well as the success of the upgrades and the ride quality of the Siskiu D5. All in all, the bike is a truly good bike even in stock form. The only thing that I don't love about it is that there is only room for a small water bottle. And honestly, that is a pretty trivial problem.

Thank you for these videos! I got the exact same bike and after two years riding it, I'm ready for some upgrades.

Nice video and upgrades., I went with the 2022 D5 because the color was so nice and the d6 in that rust copper green was so nasty I passed on it.

Would you believe the D5 was on sale just two days ago for $750?!? Wishing I had jumped on it. Nice reviews.
