A supporting frame is applied on a bicycle. The bicycle includes a main frame. In relation to the bicycle, the supporting frame has a supporting state and a folded state. The supporting frame includes a connector, a front supporting frame assembly, two connecting bars and two rear supporting frames. The connector is located on the main frame. The front supporting frame assembly includes two first pivotal connecting portions and two second pivotal connecting portions. The front supporting frame assembly is pivotally connected to the connector via the two first pivotal connecting portions. The two connecting bars both include a first connecting end and a second connecting end opposite the first connecting end. The two first connecting ends are respectively and pivotally connected to the two second pivotal connecting portions.

A portable conveyance footrest has a support portion having a substantially planar base surface to receive a foot. A tow handle portion is connected to an end of the support portion and forms a substantially planar tow handle that is within a same plane as the substantially planar base surface. The tow handle is spaced apart from the end of the support portion to define a void between the tow handle and the second end of the support portion. The tow handle is disposed within the same plane as the substantially planar base surface so that a user's fingers, when gripping the tow handle, extend into the void between the tow handle and the end of the support portion and through the plane of the substantially planar surface.

The main step structure for the saddle riding vehicle includes a fixing member, a step pin, a main step, and a biasing member that biases the main step in a developing direction. The main step structure includes an operating member supported to be rotatable relative to the main step. The operating member is provided with a contact section that makes contact with the fixing member. An engaging mechanism that can switch between an engaged state and a disengaged state of the main step and the operating member is provided. In the case where the main step is moved to an accommodated position and the operating member is made to make contact with the fixing member, the engaging mechanism puts the main step and the operating member into an engaged state.

An electric balance bike includes: a bike frame having a seat at an intermediate position thereof, a head tube at a front end thereof, and a rear fork at a rear end thereof; a front fork connected to a lower end of the head tube; a handlebar connected to an upper end of the head tube; a front wheel connected to the front fork; a rear wheel connected to the rear fork; an actuating assembly arranged between the bike frame and the rear wheel, the actuating assembly having an actuator located under an intermediate section of the bike frame, a driving member located at an axle of the rear wheel, and a driving belt that are wrapped around the actuator and the driving member; and a rechargeable lithium battery detachably connected to the actuator.

A seat rail of a motorcycle has two side members configured using fiber-reinforced resin. Each side member has a main body and an upper flange portion that protrudes in a width direction of a vehicle body from an upper side edge of the main body. An attachment element for attachment to the main frame of the vehicle body is provided at a front end portion of each side member, and the seat rail has at least one upper connecting member that connects two upper flange portions. The upper flange portion has an inflection section connecting the front section and the rear section such that the rear section of the upper flange portion is raised toward an upper direction with respect to the front section, and the inflection section is arranged between the front end portion of the side member and a foremost upper connecting member.
