An electronically actuated dropper seatpost is disclosed. The electronically actuated dropper seatpost includes an upper post and a lower post telescopically coupled with the upper post. The electronically actuated dropper seatpost also includes an electronically adjustable valve assembly configured to control a telescopic movement of the upper post and the lower post. The electronically adjustable valve assembly including a valve controlling a flow path and a motive component, wherein an electronic input to the motive component will change a flow rate of a fluid through the valve.

An electric assist bicycle includes an electric motor that generates an assistance force to assist a human force of a rider, a handle to be gripped by the rider with a hand to steer the electric assist bicycle, a manipulation device provided on the handle and including an operation switch that receives a manipulation from the rider and an alternate switch that receives a manipulation from the rider to change functions to be assigned to the operation switch, and a control circuit that performs a control to alter an operation to be executed by the electric assist bicycle depending on whether the rider manipulates the operation switch in a state of keeping the alternate switch manipulated or the rider manipulates the operation switch in a state of not manipulating the alternate switch.

A tiltable vehicle has a pair of front wheels coupled to a tiltable chassis by a tilt linkage, such that the pair of front wheels and the chassis are configured to tilt in unison with respect to a roll axis of the chassis. The tilt linkage includes a four-bar linkage having a pair of upper bar segments coupled to the chassis at spaced-apart respective inboard joints. In some examples, the inboard joints of the upper bar segments are each disposed outboard of a central chassis joint of a lower bar of the tilt linkage. An orientation sensor is configured to detect directional information regarding a net force vector applied to the chassis, and a tilt actuator operatively coupled to the chassis and configured to selectively tilt the chassis. A controller is configured to selectively control the tilt actuator based on the directional information from the orientation sensor.

A bicycle and method and bicycle assembly for a bicycle including a control device and at least one bicycle component whose operating state is variable during operation. An acoustic device with a sound converter is included for outputting information, controlled by the control device, on the operating state of the bicycle component by means of the acoustic device, and/or for capturing noises by means of the acoustic device and converting these to noise signals and utilizing them for controlling.

The invention relates to a battery (1) for electric bicycles comprising a total number N of cells (2) distributed in an optimized way, a management system (4) and at least one connector (5). The battery (1) is characterized in that it comprises a distribution with at least one additional semi-block (3b), created by at least one cell (2) separated from a block (3) or semi-block (3a) at one end (1a) of the battery (1), creating at least two spaces (6, 7). The previous space (6) is located in the semi-block (3a) of the end (1a) of the battery (1) created by the absence of at least one cell (2) and intended to connect the management system (4), and the new space (7) is in the additional semi-block (3b) created by the absence of at least a number n−1 of cells (2) and destined to house the connector (5).

A bicycle mounting mechanism and battery box assembly installed in a bicycle frame of a bicycle is provided to include a battery box and a mounting mechanism. The battery box includes an abutment recess and an opening. The mounting mechanism includes a grip and a locating component unit being connected to the bicycle frame and defining therein an accommodation chamber for accommodating the battery box. The grip is pivotally connected to the locating component unit and includes an abutment end portion and a push end portion. The abutment end portion is capable of inserting into the accommodation chamber and in engagement with the opening with a rotating of the grip. The push end portion is capable of inserting into the accommodation chamber and abuts against the abutment recess with a further rotating of the grip.

Electric power can be generated by using an existing bicycle without impairing the durability of the tire of the bicycle. The bicycle generator device (50) comprises a housing (52) configured to be attached to a frame (18) of a bicycle (10), a generator (54) attached to the housing (52), an annular rotational input member (81) for rotationally driving the generator (54), the rotational input member being rotatably mounted on the housing and positioned around a crank axis line which is a rotational center line of a crankshaft (24) and a crank arm (26) for a pedal of the bicycle, and a connecting member (90, 130) connecting the rotational input member (81) to the crankshaft (24) or the crank arm (26) in a torque transmitting relationship.

An electric tricycle with a tricycle frame, at least two pedals, and an electric motor. The tricycle frame has a steering assembly with handlebars and a front wheel and a rear wheel assembly with two rear wheels mounted on a rear axle. The pedals are rotatably coupled to the rear wheel assembly. The pedals have an engaged configuration where the pedals are engaged with the rear axle and a disengaged configuration where the pedals are disengaged from the rear axles. The electric motor is mounted on the rear wheel assembly and is electrically coupled to a battery. The electric motor is configured to engage with the rear axle when the pedals are in the disengaged configuration. The electric motor may have a forward clutch to rotate the rear axle in a first direction and a reverse clutch to rotate the rear axle in a second direction opposite the first direction.
