Junior | 120mm/120mm | ALX Alloy | 24" Wheels
Built to keep up with ambitious young riders, the Polygon SISKIU D24 is the perfect full-suspension bike for sharpening trail skills. Combining a 120mm of air suspension and lightweight ALX frame that supports full 24", mullet (26" front / 24" rear), and full 26" wheel configurations, it delivers real performance designed to adapt as your child grows. It's smarter long-term investment for progressing young riders from a single frame.
A bike that grows with your child:
The SISKIU D24 is a long-term investment in their riding. The durable alloy frame and adjustable suspension allow for easy tuning as young riders get heavier and faster. Plus, it's compatible with three wheel configurations: full 24", mullet (26" front / 24" rear), and full 26" setups that allows the bike to evolve through multiple stages of progression as your child grows, without needing to replace the entire bike.
Full-suspension Design:
With 120mm of plush travel, this bike turns intimidating obstacles into backyard play. Whether it's a technical root section or their first drop, the suspension is tuned to keep the bike planted and the rider in control, soaking up the hits that rigid bikes can’t.
Intuitive shifting for smaller riders:
The microSHIFT 1x drivetrain features an intuitive wide-range gear set for easy climbing and SpringLock chain retention. This means the chain stays exactly where it should.

Confidence starts with the brakes. We’ve spec'd Tektro hydraulic disc brakes with short-reach levers designed specifically for smaller hands. They offer massive, reliable stopping power in all weather conditions.
