START THEM STRONG
Built for growing riders ready for more adventure, the Cascade 24 delivers a confident and capable entry into trail riding. Its AL6 aluminum frame and balanced geometry provide stability, control, and comfort on longer rides and rougher paths.
SMOOTH OVER EVERY BUMP
A 50mm coil suspension fork absorbs bumps and uneven surfaces with ease, giving extra comfort and stability on trails and gravel. It helps riders stay in control when the terrain gets rougher or faster.
SIMPLE, RELIABLE CONTROL
A 1x7 Shimano Tourney drivetrain keeps gear changes simple and predictable, while Tektro mechanical disc brakes provide strong, reliable stopping power. Double wall wheels and durable tires complete a setup built for confidence and progression.

Polygon Premier Kids- Assembly Video
Your bike needs minor assembly before riding; use the tools and videos included.
As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.
Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.
