Our take on the Polygon Siskiu D24

The Polygon Siskiu D24 is a full-suspension mountain bike for kids and smaller riders, built around 26-inch wheels and an aluminum frame. Its rear shock and hydraulic disc brakes are rare at this level, where most youth bikes are hardtails with mechanical brakes. It suits riders who want real trail capability in a smaller package. The trade-off is weight and upkeep: a rear shock and hydraulic brakes add heft and service work compared with a simple rigid or hardtail kids' bike.

Questions and answers

Is the Siskiu D24 good for a first mountain bike?
Yes, if the rider fits it. Full suspension and hydraulic brakes make rough trails easier and safer than a rigid kids' bike.
What rider height does it fit?
It is sized for older kids and smaller riders on 26-inch wheels. Check Polygon's size chart against the rider's height and inseam before buying.
How does it compare with a hardtail kids' bike?
It is plusher and more capable on descents but heavier and more maintenance-heavy. A hardtail is simpler and lighter for smooth paths.
Does it come with pedals?
Most builds ship with basic flat pedals. Many owners swap them for grippier ones for trail use.
Can the suspension be adjusted for a light rider?
The rear shock and fork have adjustment, but a light rider may need a softer spring or tune. Have a shop set sag for the rider's weight.
