"Undeniably fun to ride"
"Ultra-quiet, ultra-stealthy... like you’ve always got a hand on your back, or the feeling you get when you’re having a really, really (really) good day."

"Genuinely an all-new animal for road riding"
"Most ebikes have a very bottom-heavy feel… the Domane+ SLR 9 doesn’t have any of these ride sensations. The fact that it feels more like a traditional road bike makes you want to push the limit in corners and on the flats... Feels like an acoustic bike on the open road, especially while cornering and riding tight roads."

"One of the sleekest e-road options available"
"People looking at it from a slight distance, or even up close, probably wouldn’t know that this is an e-bike...rear IsoSpeed decoupler, high-end OCLV 800 carbon material, endurance geometry, internal cable routing and generous tyre clearance that pushes this bike well into gravel territory."

"A leap forward"
"Feels smooth and natural on the road... descends confidently and feels agile… and it’s still comfortable like the regular Domane SLR."

"Lightweight, quiet and looks just like the regular version"
"If the holy grail for the best electric road bikes, or at least the path to greater acceptance, is to appear largely indistinguishable from regular road bikes, then Trek has seemingly made up serious ground."

Ultra-lightweight
The Domane+ SLR is our lightest e-bike ever, thanks to our best and lightest 800 Series OCLV Carbon and a smart frame designed to shave weight.
Designed to go the distance
An integrated 360Wh battery is hidden in the downtube and offers an impressive range of around 100 kilometers in Eco mode.
Optional Range Extender
Explore farther with an optional 160Wh Range Extender that gives you an extended total range of around 145 kilometers in Eco mode. Want even more miles? The Trek Connect App lets you customize your assist to extend your range even more.
The smooth advantage
Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger for longer.
Real road feel
A road-specific tune, narrow Q factor and intuitive mode change buttons on the hoods make the Domane+ SLR feel and handle like a traditional bike with the added benefits of electric.
All-road versatility
This Domane+ SLR comes with 32 mm smooth tyres that roll fast on tarmac roads, but has clearance for up to 40 mm tyres to enjoy every road, from smooth tarmac to gravel.
Shimano Ultegra Di2
Ultegra Di2 R8100 is Shimano’s most inspired drivetrain, packed with innovative, game-changing features. HYPERGLIDE+ technology allows for crisp, seamless shifts both up and down the gear range, even during maximal efforts. The new Di2 shifting system introduces Shimano’s exclusive wireless integrated circuit and the move to a 12-speed cassette ensures you have all the gearing you need. Ergonomics and aerodynamics have been enhanced at every turn and you can set up the drivetrain just the way you like it via Shimano’s user-friendly E-Tube app.
Connect, customise, calculate
The Trek Central app seamlessly connects to your Domane+ for real-time range calculations, activity tracking and customised motor tuning. Plus, navigation and mapping features help you stay on course wherever you ride.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
