Domane+ SLR 9 is our best category-redefining, high-speed assist carbon e-road bike that doesnt look, fit, or feel like a standard e-bike. Its 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 outings and club rides, so you stay more connected to the experience while enjoying extra power for crushing climbs and long, epic adventures. Adding the cherry on top, its equipped with the most premium parts the industry has to offer, like Shimanos road-optimized top-tier wireless electronic drivetrain — Dura-Ace Di2.
- The TQ harmonic pin ring motor is impressively discreet, compact, light, whisper-quiet, and offers a powerful assist up 28 mph
- The smart charge port, sleek integrated display, and discreet controls keep the bike looking and feeling like a traditional road bike
- Stable endurance geometry partners with road-smoothing rear IsoSpeed that absorbs bumps in the road for a smoother, more comfortable ride
- On long rides, you can add on a Range Extender that fits neatly in the bottle cage and gives you the power you need to go the extra distance
- It comes equipped with a 2x12 Shimano Dura-Ace Di2 drivetrain and fast 32mm tires for the pavement, but can fit up to 40mm tires when you want more off-road versatility
