This Trek Rail 8 GX AXS in size Large is an ex-demo bike, it has some light cosmetic damage.

The Rail 8 is Trek's top-of-the-line alloy electric mountain bike with long-travel suspension. It features a suspension set-up and parts worthy of the gnarliest enduro runs, and the powerful Bosch drive system will get you back up the mountain faster than you ever thought possible. It comes decked out with a wireless SRAM AXS drivetrain for reliable shifting that stays crisp under load.

You're after a do-anything long-travel e-MTB that can handle it all. You want serious power for steep punches or long fire roads, and the benefit of upgraded suspension on the downs. Plus, SRAM's latest wireless transmission for clean shifts and durability that you can count on.
