Bicycles
Bicycles have become more technologically advanced over time, but certain elements, such as gears and designs, have altered. Manufacturers are even recreating vintage looks due to their simplicity!
Bicycles in the early 1900s had smaller wheels, and the rear wheels were larger than the front wheel. Bikes have gotten considerably smaller in recent decades, and while most have bigger wheels, there are those with significantly narrower ones compared to previous decades.
