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 lightweight 500 Series OCLV Carbon frame and fork with rear IsoSpeed, a light, fast and efficient Fazua Evation motor and 250 Wh battery that assists up to 25 km/h. You can easily remove the Fazua drive pack (the battery and motor) from the frame and ride the bike with or without it. Plus, a Fazua controller, 2x11 Shimano Ultegra drive train and hydraulic disc brakes.
The final word
Our lightest road-smoothing Domane+ frame paired with a streamlined and efficient electric drive system. It's the best of two worlds – a 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.
The Walkthrough
favorite_borderWhy you'll love it
- This e-road bike looks, rides and feels more like a traditional road bike
- You won't feel much drag or resistance from the Fazua system when you turn it off or pass the maximum level of assist
- Road-smoothing IsoSpeed absorbs fatiguing bumps in the road for a faster, smoother, more comfortable ride
'Glorious Domane comfort; unobtrusive assistance; great range potential'
'The Domane is the ideal choice for e-assistance because the chassis is highly versatile. Its on-road manners impress, while plush IsoSpeed front and rear design means that it can handle light gravel duties, with the big-volume tubeless tyres playing their part, too.'

Features
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 customise your ride.
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 2.9 kg in weight.
Front and Rear IsoSpeed soak up fatiguing bumps in the road so you can stay stronger longer.
500 Series OCLV
500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames.

Sizing & Tech
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 retailer.
