Patent number: 11433970Abstract: A bicycle drive unit includes a housing, a crankshaft and a propulsion assist motor. The housing is configured to be mounted on a frame of a bicycle. The crankshaft is provided to the housing. The assist propulsion motor is provided to the housing to assist propulsion of a bicycle. The propulsion assist motor includes a rotational axis extending in a direction intersecting a direction in which crankshaft extends. The bicycle drive unit is configured such that a distance from a rotational axis of the crankshaft to a part of the bicycle drive unit that is the farthest from the rotational axis of the crankshaft in a direction parallel to the rotational axis of the propulsion assist motor is smaller than or equal to 210 mm.Type: GrantFiled: October 11, 2018Date of Patent: September 6, 2022Assignee: Shimano Inc.Inventors: Shinichiro Noda, Yoshinori Iino, Takuya Edamura, Kento Mitsuyasu, Takaaki Fujiwara
