Orbital Pedal Drive

I bounded out into the courtyard and halted right beside a sleek blue bicycle resting on its kickstand. Down at eye level, a sturdy black pedal with bright amber reflectors waited like an uncrewed propulsion engine! I dropped into an eager crouch, nod-nodding with wide eyes, and placed both plush mitts against the textured rubber grip. With a firm, bouncy heave, I shoved it downward. Clack-whirrrr! The pedal spun in a rapid blur, setting the chain clicking and turning the amber reflector into a dazzling golden ring. I bounced straight up on both feet and pumped my arms high to salute our active drive unit.
