safety bicycle
Noun: A type of bicycle characterized by having two wheels of equal size, where the pedals are connected to the rear wheel via a chain-driven, gear-multiplying mechanism. This design, which became standard in the late 19th century, offered greater stability and safety compared to earlier models like the high-wheel ("penny-farthing") bicycle.
The term "safety bicycle" specifically refers to the modern bicycle design that made cycling accessible and practical for the general public. It is used in historical, technical, and general descriptive contexts. - The invention of the safety bicycle revolutionized personal transportation in the 1890s. - This museum exhibit contrasts the penny-farthing with the later safety bicycle. - The key feature of the safety bicycle is its chain drive to the rear wheel.
- The term is often used in historical analysis to mark a pivotal shift in bicycle technology and social impact.
- In collector or enthusiast circles, "safety bicycle" precisely identifies bicycles from the era when this design became dominant, roughly from the 1880s onward.
- Safety bike: A common shortened, informal variant of "safety bicycle."
- Bicycle: The general term; a "safety bicycle" is the specific type that evolved into the modern bicycle.
- Chain-driven bicycle: A descriptive phrase highlighting the key mechanical feature of the safety bicycle.
- Standard bicycle
- Modern bicycle (in a historical context)
- Chain-driven bicycle
The core meaning of "safety bicycle" is defined by its contrasting features with previous designs: equal-sized wheels (for a lower center of gravity and easier mounting) and a chain-and-gear system (providing mechanical efficiency and a safer riding position). It does not refer to bicycles with specific modern safety features like lights or reflectors.
- bicycle that has two wheels of equal size; pedals are connected to the rear wheel by a multiplying gear
