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 a 504Wh battery, you will be able to hit your favorite trails with confidence!

Buy One, Plant One
Since January 2020 we have worked with not-for-profit reforestation partners to donate enough money to pay a local person a fair wage to grow, plant and guard to maturity 1 native tree for every bike we sell.
We've now planted more than 395,000 trees and counting.
