The present invention relates to an additional seat structure for electric bicycles (100) comprising a right main rod (200) and a left main rod (300), wherein each main rod (200, 300) comprises a first straight region (201, 301) and a second straight region (203, 303) with faces essentially parallel to each other, and between which there is at least one transition region (202, 302).

The disclosure provides an adjustable child's seating system for attaching to the frame of a bicycle. The seating system comprises a crossbar on which a connection hub is mounted. The connection hub attaches both a saddle and leg assembly to the crossbar. The connection hub is adjustable to adjust the angle of tilt of the saddle and/or the angle of the leg assembly relative to the saddle.

An intelligent exercise bike includes a frame, and a front wheel and a rear motor wheel, wherein the frame is provided with a pedal motor electrically connected with the pedal, and the output shaft of the pedal motor is drivingly connected with the pedal; the pedal motor has a torque sensor and a Hall sensor that are electrically connected thereto for detecting the speed and force of the pedal; a bike controller is provided in the frame, and the torque sensor and the Hall sensor convert the detected pedal speed and force into transmission signals, and output them to the bike controller; the bike controller is connected to a power supply circuit of the rear motor wheel, and the bike controller outputs a control signal to adjust the output power value of the rear motor wheel after receiving the transmission signals.

A child bicycle seat releasably mounted to a bicycle includes a seat assembly including a child seat secured to a tube member, a front tube mounted to a front end of the tube member and having top and bottom cavities, and a quick release clamp mounted to a rear end of the tube member; a handlebar assembly including a hollow pole having two opposite lower slots, a handlebar member threadedly secured to a top of the hollow pole, and a first quick release skewer secured to both the top cavity and the lower slots to fasten the front tube and the hollow pole together; a clamp assembly including a top tube having two opposite slot members, a second quick release skewer secured to both the bottom cavity and the slot members to fasten the front tube and the top tube together. The clamp assembly has a height adjustment mechanism.

A seat (1000) may include mounting components (1054a. 1054b) that may mate with corresponding components on other assemblies. The seat may include one or more features that may rotate or move to provide for coupling to the one or more assemblies. Assemblies include, but are not limited to, a stroller, a bicycle adapter, a wagon, a booster seat, a camping chair, a high chair, a stadium seat/picnic table, a hiking pack, an infant carrier, a car seat, a booster car seat, or an airline seat.

A riding vehicle includes: a main body portion supporting a wheel; a seat stay erected on the main body portion and configured to be switched between a riding state in which a person rides and a cart state in which a person does not ride; a seat fixed to an upper side of the seat stay; a frame provided on the seat stay and configured to hold luggage in the riding state and the cart state; a steering stay erected on the main body portion at an interval with respect to the seat stay in a traveling direction; and a handle provided on the steering stay, in which the frame, in the cart state, exists in a region closer to the handle as compared with that in the riding state.

A cargo bike transport carrier for transporting persons includes at least one seat element arranged inside the cargo bike transport carrier. The seat element is fastened via a holding means. According to a preferred embodiment, for ensuring good load transmission, the holding means are configured as a circumferential bracket and connecting bars.

A mounting bar, bracket, and kit have been developed such that they can couple to a head tube of the bicycle when in a first configuration and then couple to a top tube of a bicycle when in a second configuration. The bracket may be integral with the mounting bar or may be a separate component.
