Trek / Electric Road Bikes
Ride farther. Feel better doing it.
Domane+ ALR 5 is an aluminum electric road bike with a smooth, quiet, and natural-feeling boost. Its TQ HPR60 motor gives you the support you need for long rides and big climbs, while a SRAM Apex XPLR 1x12 drivetrain delivers clean, consistent shifting. The lightweight aluminum frame keeps things durable and approachable, with all-road tire clearance and mounts for added versatility.

Questions are welcome. No pressure, no bike jargon required.
The ride, not just the specs
Domane is the road bike for real roads: rough pavement, long days, and rides where you want to feel good at the end, not just fast at the start.
It's comfortable, capable, and ready for the century you keep talking about.
What makes it special
Domane+ features a TQ HPR40 motor that's lighter, smaller, and quieter to keep the bike light and the ride smooth and natural.
A lightweight and compliant 500 Series OCLV Carbon frame delivers premium Domane ride feel with builds starting at a ridiculously light 24.5 pounds.
A new riser bar adds 20mm of rise to keep you more upright and comfortable without cluttering your front end.
