An electric vehicle includes a steering element with a handle bar element. The steering element has a hand grip portion, and at a distal end a plurality of UVC light sources producing light that is incident on the hand grip portion. The UVC light sources are coupled to a controller and a power source. A platform supports a rider of the electric vehicle. The electric vehicle includes: at least one front wheel and at least one rear wheel; an electric motor configured to provide a mechanical power to at least one of the front and rear wheels; and a battery housing configured to removably receive and hold one or more battery packs, wherein the one or more battery packs are configured to power the electric vehicle.

Provided is an electric scooter with a top-swappable battery. In some embodiments, the electric scooter a frame having an opening, and a removable deck assembly disposed in the opening, the removable deck assembly comprising a deck having an upper surface and a lower surface, and a battery pack attached to the lower surface of the deck.

A electric personal mobility device may include a main body including a rider-support-platform structure and a steering column coupled to the rider-support-platform structure. The electric personal mobility device may further include a wheel arrangement, having at least one front wheel and at least one rear wheel, supporting the main body. The at least one front wheel may be steerable by the steering column. According to various embodiments, the rider-support-platform structure may include an elongate hollow housing structure enclosing an internal space partitioned to define a first and second longitudinal-internal-battery-compartments. Each longitudinal-internal-battery-compartment may be extending lengthwise along respective longitudinal side of the elongate hollow housing and having a respective rear opening at an aft portion of the elongate hollow housing structure. The rider-support-platform structure may include a rear-wheel-fork fixedly extending longitudinally from the aft portion between the rear openings. The rear-wheel-fork may be holding the at least one rear wheel.

A device includes a battery case (42) that stores a battery (62A or 62B), a lock mechanism (133) that is capable of fixing and holding the stored battery (62A or 62B) in the battery case (42), and an operation member (44) that is capable of performing switching operation of the lock mechanism (133) between a battery-fixed state and a non-battery-fixed state. The lock mechanism (133) includes a movable block (160) which is supported by the battery case (42) in a displaceable manner. The movable block (160) has a battery restriction portion (160b or 160c) which restricts displacement of the battery (62A or 62B) in a separation direction in a state of being displaced to a battery fixing position, and a holding force receiving portion (160d) which receives a holding force for maintaining the movable block (160) at the battery fixing position from the operation member (44) in a state where the operation member (44) is operated within a predetermined positional range.

Embodiments of the present disclosure relate to a chassis for a two-wheeler. The chassis includes a first downtube and a second downtube and a battery mounting system. The battery mounting system includes a movable battery housing configured to house a battery under a seat of the two-wheeler and move between a closed position and an open position, at least two support members configured to support the movable battery housing, and at least one pivot hinge coupled to a front side of the movable battery housing and supporting the movable battery housing. The at least two support members and the at least one pivot hinge are configured to enable an angular movement of the movable battery housing with respect to a seat axis between the open position and the closed position, thereby enabling replacement of the battery located under the seat of the two-wheeler, while maintaining a closed seat position of the seat.

An activity tracker includes a device that includes a sensor component, a radio, and a mounting member. The sensor component is configured to obtain bicycle route information based on information from one or more sensors. The sensor component detects pedal proximity and calculates a pedal rotation speed based on data provided by an integrated pedal cadence sensor. The radio is configured to wirelessly communicate the bicycle route information to a remote computing device. The mounting members are for mounting the device to a bicycle frame.

A seat post assembly for a bicycle has a first tube with a first distal end and a second tube with a second distal end. The first and second tubes are movable relative to one another to establish a distance between the first and second distal ends. A first pressure chamber has a loaded pressure proportional to a load applied along the tube axis. A second pressure chamber has a second pressure not proportional to the load. A flow path connects the first and second pressure chambers. A valve is disposed along the flow path and is configured to move between a closed position closing the flow path and an open position opening the flow path between the first and second pressure chambers. An isolator of the valve is configured to nullify any resultant force produced by the loaded pressure of the first pressure chamber acting on the isolator.
