To provide a drive unit for a human powered vehicle that can appropriately increase speed.SOLUTION: A drive unit for a human powered vehicle comprises: a housing; an input rotating part provided in the housing and configured so that human power driving force is inputted thereto; an output rotating part provided in the housing and configured to output the human power driving force to the human powered vehicle; and a speed changer provided in the housing and configured to change a first ratio of a rotation speed of the output rotating part with respect to a rotation speed of the input rotating part, between the input rotating part and the output rotating part, where the speed changer is configured so that a minimum value of the first ratio is equal to 1.5 or more and to 30 or less.SELECTED DRAWING: Figure 3 【課題】好適に増速できる人力駆動車用のドライブユニットを提供する。【解決手段】ドライブユニットは、人力駆動車用のドライブユニットであって、ハウジングと、前記ハウジングに設けられ、人力駆動力が入力されるように構成される入力回転部と、前記ハウジングに設けられ、前記人力駆動車に前記人力駆動力を出力するように構成される出力回転部と、前記ハウジングに設けられ、前記入力回転部および前記出力回転部の間において、前記入力回転部の回転速度に対する前記出力回転部の回転速度の第１比率を変更するように構成される変速機と、を備え、前記変速機は、前記第１比率の最小値が、１．５以上、かつ、３０以下であるように構成される。【選択図】図３
