A reciprocating mechanism includes a first connecting element, a crankshaft and a second connecting element. The crankshaft includes a rotation shaft, a first following element and a second following element. The first following element is pivotally disposed on one side of the rotation shaft and movably coupled to the first connecting element. The second following element is pivotally disposed on the other side of the rotation shaft, and a first angle is formed between the first following element and the second following element. The second connecting element is movably coupled to the second following element. The first following element and the second following element are configured to rotate around the rotation shaft so as to be movably coupled to and cause each of the first connecting element and the second connecting element to reciprocate and cyclically pivot along an arc-shaped trajectory.

Systems and methods for collecting electric scooters are described herein. In some embodiments, the systems and methods facilitate a “snaking” configuration of attaching, coupling, or fixing multiple electric scooters to one another. The snaking configuration enables multiple electric scooters to be collected together and moved to various locations, such as locations where the electric scooters can be rented, serviced, and so on. Further, the systems and methods enable any electric scooter to act as a collecting scooter, and thus a scooter share service or other fleet of scooters can manage the collection and provisioning of scooters in a location without special vehicles or equipment, among other benefits.

In an aspect there is provided a swing scooter, comprising a frame, a steering member, a front wheel, at least two support legs, and at least two platforms. A rear wheel support is pivotally attached each support leg. A rear wheel is rotatably attached to each rear wheel support. Each platform is movably attached to an associated support leg, and positioned for supporting a foot of a user. Each platform has a longitudinal platform axis and is movable between a first position in which the platform is angled down laterally towards a first lateral side of the swing scooter, and a second position in which the platform is angled down laterally towards a second lateral side of the swing scooter. The platform is movable to the first and second positions by movement of the foot of the user.

The invention relates to a vehicle, in particular a lightweight vehicle. The vehicle can be converted from a driving configuration to a seating configuration by reducing the distance between a front wheel structure and a rear wheel structure.

A rear brake assembly of a kick scooter includes a brake including an attaching member having an open end; and a visual warning device being a module and fastened in the attaching member by snapping. Also, the fastening of the visual warning device in the attaching member is done manually.

A dynamic training system provides elevated load and energy demand on a rider of a moving bicycle out on the road or track. Resistance to movement of the bicycle is provided by a resistance unit which may include an eddy current brake. A processor may generate a control signal that adjusts the resistance to replicate the effort of riding a predetermined course or training protocol. Multiple riders at different times or locations can compete on a common virtual course. A stronger rider can be restrained by a heavier imposed load to keep pace together with a weaker rider, without compromising total power expenditure to keep the riders together.

Transmission system for a manually powered vehicle includes a pedal, an overrunning clutch system having a drum, and a power link coupled at its ends to the pedal and drum. The drum has a circular portion and a fin extending radially outward from the circular portion. The power link passes over the fin and at least a part of the circular portion and has a free portion between the fin and pedal. Movement of the pedal causes movement of the power link and rotation of the drum. A transmission member is coupled to the clutch system and a rotatable drive sprocket connected to a wheel of the vehicle. Rotation of the drum causes movement of the transmission member and rotation of the drive sprocket leading to wheel rotation. Rotation of the drum in the direction opposite to the second direction does not cause movement of the transmission member.

The disclosure provides a scooter and relates to the technical field of vehicles for replacing walking. The scooter includes a head, a front wheel bracket, a front wheel, a body, a rear wheel bracket and a rear wheel. The body includes a main plate and a bottom plate, and a movable frame is arranged at the bottom plate. The dual-use of the movable frame can be realized by hinging the movable frame to the main plate, so that the movable frame can be used not only for the support when parking, but also for the protection of the body during driving. The tail lamp plate integrally connected to the bottom plate can better ensure the driving safety by setting the light-emitting surface inclined. Moreover, the guard can be easily removed for cleaning.

A foldable structure includes: a first folding seat; a second folding seat rotatably connected with the first folding seat and including a position limiting boss; and a locking assembly including a locking buckle and an unlocking part connected with each other, which are rotatably connected with the first folding seat, respectively. When the foldable structure is in an unlocked state, and the first folding seat rotates around the second folding seat in a first direction, the locking buckle moves along with the first folding seat to be engaged with the second folding seat and the unlocking part moves to abut against the position limiting boss, so that the foldable structure is switched to a pre-locked state where the position limiting boss prevents the unlocking part from rotating around the first folding seat to unlock the locking buckle.

A folding structure of a personal mobility device includes a front foot plate having an internal space and a hinge shaft at an upper end of a rear end. A rear foot plate includes a hinge shaft overlapping the front foot plate hinge shaft, at an upper end of a front end, being folded over the front foot plate or unfolded there-behind by rotating about the hinge shafts, and extending in a front foot plate extension plane when rotating to be unfolded. Apertures are formed at a rear end portion of the front foot plate. Insert protrusions protrude from a front end portion of the rear foot plate and are inserted into the internal space through the apertures when the rear foot plate is rotated to be unfolded. Locking members are disposed in the internal space, fix the insert protrusions by locking thereto, or release the fixed insert protrusions.
