Domane+ LT 7 is a carbon drop-bar electric bike designed for roadies who want an authentic road bike experience with an extra boost. The sleek and efficient Fazua drive system kicks things up a notch when you need itâlike riding into a headwind or beating your buddy up a climbâbut doesn't drag or hold you back when it's not in use. You also get the crisp, precise shifting of Shimano Ultegra Di2.
