Abstract
A bicycle includes a frame including first and second segments pivotable relative to each other between a folded position and an unfolded position. A magnet is fixed relative to the first segment. An electromagnet is fixed relative to the second segment and disposed in a magnetic field of the magnet when the frame is in the folded position. A controller is configured to power the electromagnet to repel the magnet to unfold the frame.
