Trek Domane+ ALR Electric Road Bike 2021

Designed for riders seeking an added boost on the tarmac, the Trek Domane+ ALR Electric Road Bike delivers an authentic road riding experience that shares many traits with its analogue counterpart. The sleek 300 Series Alpha Aluminium frameset houses an integrated Fazua Evation drive system that delivers a sleek aesthetic and 55Nm of hill-climbing torque. Weighing only 4.6kg with the battery included, this system is the obvious choice for the Domane+, offering longer more enjoyable rides.

There is no drag when passing the motors speed limit, leaving you free to pedal and coast without any additional friction. Three power modes offer versatile performance for any gradient and ride length and can be quickly switched with the Fazua Evation touch remote. A Shimano 105 groupset offers reliable, durable shifting across a wide 11-speed range. A Bontrager cockpit provides comfort and control, and the tubeless-ready Bontrager Paradigm Comp 25 wheelset provides smooth-rolling performance.
