Trek Rail 9 GX Black Olive/Trek Black 2023
The Rail 9 is our highest quality electric aluminum mountain bike with plenty of suspension travel. Its chassis setup and parts are suitable for the toughest enduro use, while the powerful new Bosch drive system will get you back up the mountain in no time.
It's the right bike for you if ...
... you're looking for a long-stroke e-mountain bike that gives you extra momentum without stopping you from going all out in technical terrain and taking every drop with you. Instead of investing in the frame, you'd rather invest your money in upgrades, such as a sleek chassis and high-quality parts.
This is the equipment you get
A rugged aluminum frame with a fully integrated 625 Wh battery, a quick-response RockShox ZEB suspension fork with beefy 38mm stanchions and extensive adjustability, a RockShox Super Deluxe Ultimate shock with revised Thru Shaft damping, a Bosch Performance Line CX motor with 250 watts of power and 85 Nm of torque for pedaling assistance up to 25 km/h, and a Kiox controller. You also get a SRAM GX Eagle drivetrain complete with extra-large 52-tooth climbing gear, 4-piston disc brakes for relentless downhills and 29-inch Bontrager Line Comp 30 wheels with rugged, all-tubeless Bontrager SE5 Team Issue tires complete with sealant.
Our final word
Our best aluminum-framed rail comes with major upgrades to suspension, drivetrain, seatpost and more. If you're looking for an e-mountain bike that can keep up with our best long-travel trail bikes in terms of features and handle descents just as confidently, you've found it here.

Each Trek carries a simple promise: We’ll take care of you and do what's right.
The path to superior performance is paved with curiosity. In 1976, Trek was founded on a question: Why are no high-performance bikes made in the United States? Today, Trek gives the brightest and most passionate cycling designers and researchers the resources to question everything. Because innovation happens only when you have the courage to ask the hard questions and go where no one has gone before. To lead, you must invent.

Trek Bicycle Corporation
Trek from Waterloo has been developing and manufacturing extremely high-quality bicycles since 1976. It all started in this red shed. By specializing in high-end MTB and racing bikes, they have gathered a lot of know-how over the years, which has led to countless victories for their racing drivers. Be it the dominance of Aaron Gwin and the Athertons on the Trek Session, the victory of Fabian Cancellara on the cobblestones of Paris Roubaix or the world title of Mads Pedersen. Trek riders such as Brandon Semenuk, Brett Rheeder and Emil Johansson also set standards worldwide in the freeride sector. This success is only possible with the best material and that is what Trek offers its athletes.
