Vintage 'Rin girl' Step-Through Bicycle

This is a vintage step-through bicycle, likely a 'Rin girl' model, characterized by its bright yellow frame and small-diameter wheels. The frame is constructed from metal tubing, painted in a solid, vibrant yellow color that shows significant sun fading and surface grime, particularly on the top tube and chainstays. The design features a low-slung, curved top tube that angles downward, indicating a step-through or mixte frame style, common for easier mounting and dismounting. The bicycle is equipped with fenders over both the front and rear wheels; these appear to be made of metal and are heavily rusted and discolored, suggesting prolonged outdoor exposure. There is a matching yellow metal rear rack integrated into the frame structure, designed for carrying packages or panniers. The seat is black, made of a synthetic material, and shows some wear and age-related deterioration. The handlebars are upright and appear to have a slight rise, featuring brown or dark-colored grips that are also showing signs of age. A small headlamp is visible on the front fork. The wheels are small, possibly 20-inch or similar, with whitewall tires that are now discolored to a brownish-yellow. The spokes and rims are visibly rusty. A white plastic or metal disc cover is attached to the front wheel spokes. The drivetrain includes pedals that appear to be made of metal with rubber inserts, showing rust and wear. The overall condition suggests significant neglect and exposure to the elements, with extensive rust on metallic components (fenders, chain, spokes, rims, handlebars, seat post) and paint degradation. This style of bicycle, with its compact frame and small wheels, was popular in the 1960s-1970s, making its estimated age within that period. The 'Rin girl' branding is visible on the diagonal tube of the frame.
