Domane+ is a performance electric road bike built for real road riding, with a natural-feeling assist up to 28 mph. It looks like a road bike, handles like a road bike, and rides like the bikes you already love. But when the road kicks up and the miles stretch out, Domane+ gives you a smooth boost to keep you going. And now, Domane+ SL brings even more range to the ride with a lighter, more compact TQ HPR40 motor and your choice of battery size in Project One.
Choose your Domane+
Two ways to get more from every road ride. Choose lightweight carbon with custom range and build options, or go with aluminum for a more affordable all-road option with a subtle electric assist built in.

The carbon Domane+ difference
Domane+ SL is our lightest and longest-range e-road bike ever, with more comfort, built-in visibility, and the ability to customize in Project One.
Sleek riser bar
A riser bar cleanly adds 20mm of rise to keep you more upright and comfortable without cluttering the front end.
Road-smoothing seatpost
Domane’s seatpost is designed to flex vertically and absorb road chatter so you can ride stronger longer.
500 Series OCLV Carbon frame
A lightweight carbon frame helps take the edge off rough roads while keeping the ride quick and responsive.
Integrated lights
Built-in front and rear lights powered by your bike’s main battery make it easy to see and be seen out on the road.
Choose your battery size, parts size, and paint in Project One
Lightweight build or long-range battery? Matte or metallic? 160 or 170mm cranks? Build your carbon Domane+ exactly how you want it — from parts to paint — and customize your bar width, crank length, and more at no extra cost.
