Description

EMPOWER YOUR RIDE

The Siskiu T6E is a 150/140mm full-suspension all-mountain e-bike built for tackling anything from epic adventures to lap after lap of your local trails. Featuring modern geometry, a mullet-compatible design thanks to its built-in flip chip, and a powerful motor, enjoy the freedom to explore and conquer more challenging terrain.

SHIMANO STEPS EP6 / 504Wh

The Shimano EP6 motor takes everything we love about the top-of-the-line EP801 at a slight weight penalty. So that means you still get 85nm of intuitive and efficient power you need to tackle steep climbs. Combined with a dropper post, 4 piston brakes, and 504Wh battery you will be able to hit your favourite trails with confidence!

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.

INDUSTRY REVIEWS

"Polygon's 2024 range has been knocking it out of the park on value and handling - and the Siskiu T6E trail e-bike is no different." - AMB

SUNTOUR ZERON BOOST FORK

SR Suntour’s Zeron Boost 35 fork features 150mm of travel, Remote control air pressure adjustment and (PCS) tech to help improve small bump sensitivity.

SUNTOUR EDGE PLUS SHOCK

SR Suntour’s Edge plus rear shock features adjustable rebound damping and remote lockout, giving this air spring the ultimate in tunability.

SHIMANO DEORE 1X10 DRIVETRAIN

The Shimano Deore drivetrain is paired with an 11-46T cassette, giving you a massive gear ratio to get up and down the mountain easily.

SRAM CODE R 4-PISTON BRAKES

SRAM Codes Rs feature some handy tech like SRAM heat shield, tool-free reach adjustment and a powerful 4-piston design paired with 203mm rotors.

FLIP-CHIP

Switch between a full 29" wheel setup (LOW) or a mixed "mullet" setup with a 27.5" rear wheel (HIGH). This allows you to customize the bike's handling characteristics for different terrain and riding styles while maintaining optimal geometry.

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.

Please follow the video playlist below to complete the setup of your new bike correctly.
