A foldable bicycle has a frame with a seat tube, a down tube and a top tube. An inclined strut is pivotable with the top tube and with an openable connection to the down tube. The down tube is connected with a joint to a crankshaft bearing housing so that a rotation axle in this joint is turned to form an angle to a line substantially parallel to the crankshaft bearing housing's longitudinal axis. The top tube is connected through a joint to the seat tube so that a rotation axle in this joint is turned to form an angle around the seat tube's longitudinal axis. The top tube is at its other end that's opposite the seat tube connected with a joint to the head tube so that a rotation axle in this joint is substantially perpendicular to the longitudinal axes of both the head tube and top tube.

A two-wheeled vehicle includes a frame having a front frame portion, a mid-frame portion, and a rear frame portion. The mid-frame portion is coupled to the rear frame portion and the front frame portion. The vehicle further includes a plurality of ground-engaging members for supporting the frame. The front frame portion is removably coupled to the mid-frame portion with a plurality of frame members extending between the front frame portion and the mid-frame portion.

A motorized and controllable wheel system for a non-motorized stander is disclosed. Micro-controllers are programmed to be capable of acquiring and processing multiple inputs from the user and therapist and controlling the motors. Additional sensors are implemented in order to enhance safety and provide some device autonomy with the goal of providing a device that improves the mobility, autonomy, and educational experience of children.

In the vicinity of a front end of a plate-shaped member of a fiber reinforced resin material having long fibers, to suppress deterioration in strength due to waviness of the long fibers during press-molding. The plate-shaped member is formed by a discontinuous fiber reinforced resin having long fibers. A flat surface part of the plate-shaped member is provided with a hole part, and a side wall is integrally formed to a semicircular end of the flat surface part located closer to the hole part. The side wall is arranged in a region between an opening edge of the hole part closer to a front end, and the front end so as to extend around its outer circumference.

A saddle type vehicle includes a seat rail and a seat that is attached to the seat rail. The seat rail includes an outer edge that is placed on an outward side in a vehicle body width direction and an inner edge that is placed on an inward side in the vehicle body width direction and higher than the outer edge. On the other hand, the seat includes a sitting part. When the sitting part sits on an upper surface of the inner edge, a side part of the seat surrounds (covers) the sitting part.

The radiator is disposed between the accommodation box and a front wheel. A rear edge lower portion, which is at least part of a rear edge, of the cover with which an opening of the accommodation box can be closed and opened is inclined obliquely in side view of the vehicle body, and the cover is supported in an opening-forward manner with reference to a support shaft disposed along the inclination.

A two-wheeled vehicle includes a frame, a front ground-engaging member, a rear ground-engaging member, and a rear suspension assembly operably coupled to the rear ground-engaging member. The rear suspension assembly includes a first swing arm, a second swing arm, and a pivot axle extending between the first and second swing arms. And, rotation of the pivot axle is configured to adjust the position of a portion of the frame relative to the first and second swing arms.
