Trek Domane+ SLR 7 Ultegra Di2 Electric Road Bike 2025 in Carbon Smoke Prismatic Marble

The Domane+ SLR 7 is a category-redefining carbon e-road bike that doesn’t look, fit or feel like a standard e-bike. It’s built on an 800 Series OCLV Carbon frame that hides a compact and refined motor to elevate your ride with natural-feeling assist. The motor quietly blends in with the elements, all but disappearing under you on peaceful solo spins and club rides, so you stay more connected to the experience while enjoying extra power for crushing climbs and long, epic adventures. Plus, it offers the ultra fast shifting of a Shimano Ultegra Di2 drivetrain.

You’re looking for a high-end carbon e-road bike that’s super light, super discreet and super quiet. Versatility is important, and you want the ability to roll on everything from smooth tarmac to rough gravel. You also want the performance upgrade of a quick and precise Ultegra Di2 wireless electronic drivetrain.
