1. A convertible, push-bicycle for a child, comprising:
- a steering mechanism operably connected to a front wheel and a frame, the frame operably connected to a rear wheel and a collapsible crankset, the collapsible crankset (i) including a spindle, two crankarms, and two collapsible pedals and (ii) configured to be convertible from a pedaling position to a backward-retracted position; and
,a housing operably connected to the frame and having a recess configured to receive the two crankarms and the two collapsible pedals in the backward-retracted position for protecting a child'"'"'s legs from the collapsible crankset in the backward-retracted position;
wherein,the spindle is connected at each end to one of the two crankarms, at least one of the crankarms reversibly articulating with respect to the spindle up to at least about 180 degrees through a reversibly fixable hinge joint, the articulation of the crankarm retracting the crankset from the pedaling position to the backward-retracted position;
each of the pedals articulating with its respective crankarm from (i) the pedaling position in which the pedal is at least substantially normal to its respective crankarm to (ii) the backward-retracted position in which the pedal is at least substantially parallel with the position of its respective crankarm for collapse into the housing to protect the child'"'"'s legs; and
,the crankset remains entirely intact for converting from a pedal-powered bicycle to a push-powered bicycle without requiring disassembly and re-assembly of the crankset during the process of teaching the child how to ride the convertible push-bicycle.

Abstract
An articulable crankset for converting a pedal-powered vehicle into a push-powered vehicle is provided. The articulable crankset can be in a retracted position to provide at least less of an obstruction to a user'"'"'s legs during use of the push-powered vehicle than a non-retractable crankset. The vehicle can be a bicycle, and the articulable crankset can be a component of a production bicycle or a component of a conversion kit that will convert a bicycle from a pedal-powered bicycle to a convertible bicycle that can also function as a push-powered bicycle.

7. A convertible, push bicycle for a child, the bicycle comprising:
-
a steering mechanism operably connected to a front wheel and a frame, the frame operably connected to a rear wheel and a collapsible crankset, the collapsible crankset (i) including a spindle, two crankarms, and two collapsible pedals and (ii) configured to be convertible from a pedaling position to a backward-retracted position or a forward-retracted position; and
a means for reversibly fixing the crankset into the forward-retracted position or the backward-retracted position; and
,a housing operably connected to the frame and having a recess configured to receive the two crankarms and the two collapsible pedals in the backward-retracted osition for protecting a child'"'"'s legs from the collapsible crankset in the backward-retracted position; wherein, the spindle is connected at each end to one of the two crankarms, at least one of the crankarms reversibly articulating with respect to the spindle up to at least about 180 degrees through a reversibly fixable hinge joint;
