BikesOnline have continued to deliver mountain bikes to riders around Australia who are looking for a great value way to get onto the dirt. The Polygon Siskiu range has always been popular, and the more recent updates to the frame designs and models available have only served to increase their popularity – there are even two e-bike models now, with the T6E and T7E, the former of which we have tested in late 2023. While Mike has also tested the $2299 Siskiu T6 in this issue, BikesOnline also released the new $4299 Polygon Siskiu T9 in early 2024.
The Siskiu T9 shares the same frame as the rest of the range, including the size specifc wheel sizing. This trail bike is available with 27.5” wheels in small and medium frame sizes, with 150/140mm of travel front and rear respectively. For sizes from medium to extra large, the bikes are built with 29” wheels and the travel is a 140/135mm setup. So if you’re medium-ish size, you can choose what wheel size you’re after. I’m testing a medium 29er from BikesOnline.
