SISKIU D24: For the Next Generation
SISKIU D24 2024
Features
-
Built-In Growth & "Mullet" Compatibility
The SISKIU D24 is a long-term investment in their riding. The durable alloy frame and adjustable suspension allow for easy tuning as they get heavier and faster. Plus, it’s mullet-compatible, meaning you can swap in a 26" front wheel as your child grows to give them even more rollover capability and stability.
-
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.
-
Smart Shifting & Chain Security
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.
-
Youth-Specific Hydraulic Power
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.

FAQ
-
How do I teach my child to ride on mountain trails?
Start on easier trails with smooth terrain, and gradually move to more challenging trails with rocks and roots. Teach them to brake properly, maintain a safe speed, and ride with proper body positioning. Supervision is key for beginners.
-
What accessories should I buy for my child’s MTB?
Key accessories include a helmet, knee and elbow pads, gloves, and a hydration pack. You may also want to consider a bike lock, lights, and a bike repair kit for any potential trail-side fixes.
-
How can I make the bike more comfortable for my child?
Ensure the seat is properly adjusted for their height and comfort. Consider adding padded grips or a more comfortable saddle if necessary. Properly adjusted brakes, gears, suspension, and levers also help ensure a smoother and more enjoyable ride.
-
What is the ideal gear ratio for a junior mountain bike?
A gear ratio with a low enough range allows young riders to easily climb hills and ride on varied terrain without feeling overwhelmed. The Polygon Siskiu D24 have simpler gear systems (1x drivetrains) that offer fewer gears but still provide adequate range for most trails.
