Definition
A safety bicycle is a type of bicycle with two wheels of the same size and a chain drive to the rear wheel. 🚲 It's the standard bicycle design we see everywhere today. It contrasts sharply with the earlier high-wheel bicycles that were quite dangerous. The safety bicycle's lower center of gravity makes it much easier and safer to ride. Think of it as the bicycle finally growing up. It marked a huge leap forward in cycling. 👍
