Trek Domane+ SLR 7 Electric Road Bike 2025
If you're in the market for a high-end carbon e-road bike that’s lightweight, discreet, and incredibly quiet, the Domane+ SLR is an ideal choice. It excels in versatility, allowing you to tackle everything from smooth roads to rough gravel. With the added precision of an Ultegra Di2 wireless electronic drivetrain, this road bike offers a premium ride experience that’s efficient, responsive, and performance-driven.
The Domane+ SLR features a super light 800 Series OCLV Carbon frame with rear IsoSpeed, paired with a compact 50 Nm TQ harmonic pin ring motor that provides smooth assistance up to 20 mph (25 km/h in Europe). The 360 Wh integrated battery, along with a smart LED display and top-mounted controls, ensures seamless operation. The bike also includes Aeolus Pro 37 OCLV Carbon wheels, vibration-damping Bontrager Pro Iso-Core handlebars, and a fully integrated cable system for a sleek appearance. For longer rides, the Range Extender adds power, while its endurance geometry and 40 mm tyre clearance provide stability and comfort across a range of terrains.
