Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

The present disclosure provides a multifunctional children's ride-on vehicle including a frame, a vehicle head, a front wheel, pedal mechanisms, a rear frame, a seat, rear wheel brackets, rear wheels, and a push rod. The frame is provided with a plurality of adjusting grooves, and the plurality of adjusting grooves are evenly distributed along the frame. The rear frame is provided with an adjusting block corresponding to the adjusting groove, and the adjusting block is embedded into the adjusting grooves. The frame is provided with a frame accommodating groove at the front end thereof, and the frame accommodating groove has a size same as that of the adjusting groove.

A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.

A steering wheel assembly for use with a ride-on vehicle which has a frame with at least two wheels. The steering wheel assembly comprises a steering rod operatively coupled to the frame of the ride-on vehicle. The steering rod includes a chuck secured to the steering rod. The chuck includes a body extending between a base and an upper end. The steering wheel assembly further comprises a steering wheel with a sleeve adapted to be coupled to the chuck in a tool-less manner such that the steering wheel is configured to be engaged by a rider for moving the steering wheel and thereby steering the ride-on vehicle.

A bike includes a frame elongated in a longitudinal direction, a front fork rotatably engaged with a front wheel at a front end of the bike, a rear fork rotatably engaged with a rear wheel at a rear end of the bike, a handlebar supported for rotation at the front end of the frame for steering the bike, and a drive module configured to drive the rear wheel of the bike when operated selectively with power. The frame includes a down tube extending downward and rearward from the front end of the bike and a drive module enclosure formed at a second end of the down tube. The drive module enclosure defines a drive module receptacle that is open along the longitudinal direction of the bike. The drive module receptacle is sized to receive the drive module along the longitudinal direction of the bike.

A running bike that can be operated selectively with and without power. The running bike includes a front fork rotatably engaged with a front wheel, a rear fork rotatably engaged with a rear wheel, the rear fork having an upper portion and a lower portion, and a handlebar rotatably engaged with the front fork for steering the running bike. A frame extends between and connects the front fork and the rear fork. The frame includes a down tube having a first end connected to the front fork and a second end opposite the first end and positioned adjacent the rear fork, a top tube connected to and extending between the down tube and the upper portion of the rear fork, and a drivetrain receiving region defined as an area rearward of the down tube, forward of the rear wheel, and below the top tube.
