For their Rail ebikes, Trek has partnered with Bosch to build bikes with reliable and high-performing electrical components. The Rail 9 is our 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 and an ultra-tidy cockpit.
