Compact, quiet, and mighty e-system

The TQ harmonic pin ring motor is super efficient with an amazing range-to-weight-to-speed ratio. Its ultra-compact, whisper-quiet, and offers an unbelievably natural-feeling assist up to 28 mph.

Ultra-lightweight

Domane+ SLR is our lightest e-bike ever, weighing only ~26 pounds thanks to our best and lightest 800 Series OCLV Carbon and a smart frame designed to shave weight.

Designed to go the distance

An integrated 360Wh battery is hidden in the downtube and offers an impressive range of around 60 miles in Eco mode.

Optional Range Extender

Explore farther with an optional 160Wh Range Extender that gives you an extended total range of around 90 miles in Eco mode. Want even more miles? The Trek Connect App lets you customize your assist to extend your range even more.

The smooth advantage

Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger longer.

Real road feel

A road-specific tune, narrow Q factor, and intuitive mode change buttons on the hoods make Domane+ SLR feel and handle like a traditional bike with the added benefits of electric.
