A tensioner for an electric bicycle includes: a rotatable first wheel body 31 that meshes with a driving force transmission member 6 from one side which is the same side as an auxiliary drive wheel body 18, and a rotatable second wheel body 32 that meshes with the driving force transmission member 6 from the other side opposite to the auxiliary drive wheel body 18. The first wheel body 31 is located behind the auxiliary drive wheel body 18 and is movable in a tension increase/decrease direction G in which the tension of the driving force transmission member 6 increases or decreases. Furthermore, the first wheel body 31 is biased by a biasing member in a direction in which the tension of the driving force transmission member 6 increases. The second wheel body 32 is fixed between the auxiliary drive wheel body 18 and the first wheel body 31.
