A rotation locking device includes a locking module and at least one engaging member. The at least one engaging member is rotatably coupled to the locking module. The locking module is configured to engaging and disengage the at least one engaging member, thereby refraining the at least one engaging member from rotating relative to the locking module.

An actuation device for a human-powered vehicle comprises a base member, a movable member, and an actuator. The movable member is movably provided on the base member. The actuator is configured to be actuated by stimulation including at least one of electric stimulation and heat stimulation so as to move the movable member relative to the base member in a first direction by pulling the movable member.

An actuation controller for a rider posture changing device of a human-powered vehicle comprises a detector and a controller. The rider posture changing device includes a first member, a second member, and an electrical actuator configured to move the second member relative to the first member. The detector is configured to detect actuation information relating to an actuation state in which the electrical actuator moves the second member relative to the first member. The controller is configured to evaluate the actuation state in accordance with the actuation information detected by the detector.

A seat dropper remote device has a base portion, central portion and paddle portion. The base portion has a mounting plate for mounting to a bar clamp on a bicycle handlebar and a base bolt hole. The mounting plate has a mounting slot to receive a mounting bolt. The central portion is connected with the base portion, receives an actuation cable, and includes a body having a body bolt hole. The device includes a paddle portion that is connected with the central portion, actuates the actuation cable, and has an assembly bolt cavity and an assembly bolt. The assembly bolt passes through the assembly bolt cavity, body bolt hole, and base bolt hole. The assembly bolt provides rotational adjustment of the paddle portion and the mounting bolt provides lateral adjustment of the paddle portion. The lateral adjustment, rotational adjustment, and actuation of the actuation cable operate independent of one another.

A bicycle frame sealing means includes a frame-side sealing element adapted to be sealingly connected with a saddle tube of a bicycle frame. A saddle post-side sealing element is adapted to be sealingly connected with a saddle post. Both sealing elements are interconnected by means of a flexible connecting elements, so that relative movements can occur between the two sealing elements or between the saddle tube and the saddle post, while a good tightness is still ensured.

A bicycle frame includes a front triangle comprising a head tube and a bottom bracket shell, a tension bar comprising a first end and a second end, wherein the first end of the tension bar is pivotably connected to an upper portion of a telescoping seat post assembly, and a first fore pivot assembly at a first reach point. The first reach point is between a reach point of the bottom bracket shell and a reach point of the head tube. The first fore pivot assembly is pivotably connected to the second end of the tension bar. The frame further includes an aft pivot assembly at a second reach point, wherein the second reach point is closer to the reach point of the bottom bracket shell than the first reach point, and wherein the aft pivot assembly is pivotably connected to a lower portion of the telescoping seat post assembly.

A straddle type electric vehicle comprises a main frame, a motor unit including an electric motor, and a battery that supplies power to the motor unit. The main frame includes a left and right pair of portions. The motor unit is disposed overlapping the main frame in a side view of the vehicle. A motor shaft of the electric motor is disposed above the pivot shaft and rearward in the vehicle longitudinal direction.
