ADVENTURE STARTS HERE

The Cascade 4 is the perfect gateway to riding offroad. It's ideal for new riders who want a mountain bike with knobby tyres that can double as a rugged commuter. Disc brakes, front suspension, 24 speeds, and mounts for a rack and mudguards make this versatile ride an excellent entry point for new trail riders and commuters alike.

LIGHTWEIGHT ALLOY FRAME

Aluminium has been the go-to material for bikes since the late 90s. Polygon uses an aluminium blend that is lighter and more durable than its peers. Featuring 6061, triple-butted, heat-treated tubing for strength and durability, ALX was built to last. Complete with rack and water bottle mounts the Cascade is ready for any adventure

Assembly

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.

Very nice bike!!

This bike is so pretty and works great! The seat was a little too high for me even at its minimum. So I had to shorten the post slightly to fit me better. Other than that the bike has been wonderful!
