Description

BEST 1ST FULL SUSPENSION

The perfect upgrade for adventurous kids (ages 7-11) ready to take on bigger challenges. Its full-suspension design with 120mm travel is built to handle rocks, roots and jumps. Plus, it's mullet-compatible, so you can upgrade to a 26" front wheel as your child grows, extending the life of the bike and their riding progression!

VALUE MEETS PERFOMANCE

Built around a durable alloy frame, the D24 EVO features custom-tuned air suspension for lighter riders, offering superior performance that can be easily adjusted as they grow. The Shimano Cues 1x10 drivetrain ensures smooth shifting on any terrain, while hydraulic disc brakes provide reliable stopping power. Plus, the included dropper post boosts confidence and control on descents.

A TRUSTED BRAND

Polygon is a factory-direct brand with over 30 years of experience crafting high-performance bikes at competitive prices. Vertically integrated manufacturing ensures quality and cost savings. Their mountain bikes have been tested on the world stage at events like Redbull Rampage and the World Cup circuit, boasting a 5-year frame warranty for peace of mind.

X-FUSION VELVET FORK

The X-Fusion Velvet fork and 02 PRO R rear shock are custom tuned for young shredders light weight, allowing them to get the most out of the 120mm of travel. The air springs can be easily adjusted with a shock pump to match your child's weight and riding style.

SHIMANO 1x10 DRIVETRAIN

The Shimano Cues 1x10 drivetrain delivers smooth, reliable shifting and the 11-48t cassette offers plenty of range to get up steep climbs. Thanks to the clutch rear derailleur, there is no clunking or rattling from the drivetrain and less dropped chains!

HYDRAULIC DISC BRAKES

Tektro hydraulic brakes provide tonnes of power and all weather performance. Levers specifically designed for small hands are easy to reach and will save any rider in a sticky situation.

DROPPER POST

The TranzX dropper post allows for quick and easy saddle height adjustment on the fly, improving your child's control and confidence on descents and technical sections.

WHEELS & TYRES

Entity X15 Disc wheels are lightweight and durable, and come pre-taped for easy tubeless setup. The stock Vee Tyres off loads of grip and puncture protection! For a full tubeless setup, you will need valves, sealant and tubeless ready tyres.
