About this product

The Polygon Siskiu D6 SE is a 2026 model mountain bike designed for unisex adults, featuring an aluminum frame and 27.5-inch wheels. It comes in an eye-catching orange color and is equipped with hydraulic disc brakes for superior stopping power. The bike boasts a flat bar handlebar, thumb shifters, and derailleur gears for efficient gear changes. Additional features include an adjustable seat and a 1-year manufacturer warranty, all packaged in a new, unopened box.

Our take

This Polygon Siskiu D6 SE looks promising for a mid-range mountain bike, especially being a 2026 model. The aluminum frame is a plus for balancing strength and weight, and the hydraulic disc brakes are a definite advantage for reliable stopping on trails. I appreciate the 27.5-inch wheels for a good mix of agility and rollover capability. The adjustable seat is standard but always welcome. However, the 27-inch frame size, while labeled 'L,' might be a bit ambiguous without a more specific measurement, and a flat bar isn't always ideal for extended technical descents. Overall, a solid option for trail enthusiasts.
