$12,499.99 Model 32579

Domane+ LT 9 is a high-end carbon drop-bar electric bike designed for roadies who want an authentic road bike experience with an extra boost. The sleek and efficient Fazua drive system kicks things up a notch when you need it—like riding into a headwind or beating your buddy up a climb—but doesn't drag or hold you back when it's not in use. You also get the high-performance benefits of Shimano's best electronic drivetrain, Dura-Ace Di2.

It's right for you if...

You're an avid road rider searching for an e-bike that looks and rides like a traditional road bike. You want an electric drive system that's so lightweight and efficient you almost won't notice it until you flip the switch for a strategic boost of power.

The tech you get

A 500 Series OCLV Carbon frame and fork with rear IsoSpeed, a light, fast, and efficient Fazua Evation motor and a 250Wh battery that assists up to 20 mph. You can easily remove the Fazua drivepack (the battery and motor) from the frame and ride your bike with or without it. Plus, a Fazua controller, 2x11 Shimano Dura-Ace Di2 electronic drivetrain, Bontrager Aeolus Pro 3V carbon wheels, and hydraulic disc brakes.

The final word

Our road-smoothing Domane+ frame paired with a streamlined and efficient electric drive system, plus Shimano's highest-end electronic drivetrain. It's the best of two worlds—true road bike feel with an additional thrust of power when you want to crush a climb or push yourself to pop off a few more miles.

Features

Fast and efficient

Fast and efficient

Fazua's lightweight drive system adds a punch of power when you need it, but rides and feels like a traditional bike when you don't. You won't feel much drag or resistance when you turn it off or pass the max level of assist. The system is also compatible with a smartphone app to let you check battery status and customize your ride.

Removable drivepack

Removable drivepack

When your ride doesn't require an extra boost, replace the motor and battery with the storage cover (sold separately) to turn your bike into a regular Domane. You'll also save 2.9kg in weight.

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
