Abstract
A push bike includes a frame, two wheel assemblies and two locking assemblies. The frame includes a curved bottom portion. The two wheel assemblies are pivotally connected with two opposite ends of the frame respectively. Each wheel assembly includes at least one wheel being contactable with the ground, and a limiting portion. Each locking assembly disposed in the frame and includes a limiting member abuttable against the limiting portion. Thus, the two wheel assemblies can be pivoted or locked with respect to the frame to cause the curved bottom portion to contact with the ground for rocking.

A push bike comprising:
- a frame including a top portion and a curved bottom portion spaced form the top portion, and at least one first connecting portion formed between the top and bottom portions;
- at least one wheel assembly including a second connecting portion pivotally connected with the first connecting portion of the frame, at least one wheel spaced from the second connecting portion and contactable with the ground, and a limiting portion disposed between the second connecting portion and the wheel;
- and
- at least one locking assembly mounted on the frame and adjacent to the first connecting portion, with the locking assembly including a limiting member movable with respect to the frame between locking and releasing positions, with the limiting member abuttable against the limiting portion of the wheel assembly and including a first end adjacent to the bottom portion of the frame, and a second end spaced from the first end and adjacent to the top portion of the frame;
- wherein when the limiting member is in the locking position, the limiting member is spaced from the frame, with one of the first and second ends of the limiting member abutting against the limiting portion of the wheel assembly to cause the wheel assembly unable to pivot with respect to the frame;
- wherein when the limiting member is in the releasing position, the limiting member is close to the frame, with one of the first and second ends of the limiting member disengaging from the limiting portion of the wheel assembly to cause the wheel assembly pivotable with respect to the frame between first and second positions;
- wherein when the wheel assembly is in the first position, the first end of the limiting member abutting against the limiting portion of the wheel assembly, with the wheel of the wheel assembly contacted with the ground;
- wherein when the wheel assembly is in the second position, the second end of the limiting member abutting against the limiting portion of the wheel assembly, with the bottom portion of the frame contacted with the ground.
