Abstract: An operating unit for a bottom bracket drive of an electric bicycle is attachable to a handlebar of the bicycle at a handlebar grip and includes at least one actuating element movable, starting from a neutral position, in either a first actuation direction or in a second actuation direction at a time by a finger of a user. Each particular actuating element is movable, in either actuation direction, from the neutral position into at least two functional positions arranged one after another, and returns to the neutral position when released. A first actuating force is required to move the particular actuating element into a first functional position of the at least two functional positions, and a second, greater actuating force is required to overcome a noticeable pressure point and to move the particular actuating element into at least one second functional position of the at least two functional positions.
