The evolution of the bicycle in the 21st century.

 As more people embrace cycling as a mode of transportation and recreation, we can expect to see continued innovation in the years to come. Electric bikes, or e-bikes, have become increasingly popular in recent years providing an alternative to traditional bicycles for those who want a little extra help with pedalling, making it easier to ride up hills and travel longer distances. With more people living in urban areas and limited space for storage, folding bicycles have become popular for their compactness and portability. These bikes can be easily folded up and stored in small spaces making them ideal for commuters or anyone who needs to travel with their bike. Carbon fibre frames have become increasingly common in high-end bicycles, offering a lightweight and durable alternative to traditional metal frames. Carbon fibre is also known for its ability to absorb vibrations, providing a smoother ride. Smart bikes are equipped with sensors and technology that can track speed, distance, and other metrics. Some even have built-in GPS and navigation systems. These bikes can connect to smartphones or other devices, allowing riders to track their progress and adjust their rides accordingly. Bike sharing programs have become popular in cities around the world providing a convenient and affordable way for people to get around without relying on cars. These programs typically offer bicycles that can be rented for short periods of time, making them ideal for short trips or sightseeing.
