Bicycle stabilizing assembly

A bicycle stabilizing assembly configured to couple to a frame of a bicycle, the bicycle stabilizing assembly comprising:

• a mounting bracket having a front surface and a back surface, the mounting bracket configured to engage at least one of a seat stay and a chain stay of the frame of the bicycle, the mounting bracket comprising:
• a plate portion comprising a bottom edge, a side edge, a top edge extending between the bottom edge and the side edge, and a socket disposed substantially adjacent to the bottom edge, the top edge including a first end adjacent to the side edge and a second end adjacent to the bottom edge;
• and
• a substantially planar track portion extending along the top edge such that the plate portion is substantially parallel to the track portion, the track portion comprising at least one arcuate channel extending between the front surface and the back surface, wherein the at least one arcuate channel comprises an arc extending between the first end and the second end such that the arc spans at least a distance between the seat stay and the chain stay of the frame of the bicycle, the at least one arcuate channel configured to slidably receive a retaining bracket along the arc to engage the seat stay or the chain stay;
• and
• a stabilizing arm comprising an elongate bar including a distal end and a proximal end, wherein the proximal end is configured to rotatably engage the socket such that an orientation of the stabilizing arm with respect to the mounting bracket is selectively adjustable, and wherein the distal end is configured to retain a training wheel at a desired height relative to the distal end.
