What are the differences between Folding Bike Single Chainwheel & Crank Set compared to multi-chainwheel systems?

Compared with the multi-chainwheel system, the Folding Bike Single Chainwheel & Crank Set has the following main differences:
Design and structure:
Folding Bike Single Chainwheel & Crank Set adopts a single chainwheel design with a simple structure and fewer parts. This design makes the entire system more compact, which is particularly suitable for folding bicycles, which require high portability and space efficiency.
Multi-sprocket systems contain multiple sprockets to provide different shifting options. This adds complexity and weight to the system, but also gives the rider more gearing options.
Shifting ability:
The Single Chainwheel & Crank Set's shifting capabilities are relatively limited because it only has a fixed gear ratio. This means the rider cannot adjust the gear ratio based on road conditions or needs to accommodate different riding conditions.
The multi-sprocket system provides a wide speed range through different sprocket combinations. Riders can adjust the gear ratio as needed to better cope with different conditions such as climbing, descending or flat riding.
Weight and portability:
Folding Bike Single Chainwheel & Crank Sets are generally lighter than multi-chainwheel systems due to simpler construction and fewer components. This is an important advantage for a folding bike, as the lighter weight means it is easier to carry and store.
Multi-sprocket systems typically weigh more due to their more components and complex structure, which may affect the portability of a folding bike.
Maintenance and durability:
The structural simplicity of the Single Chainwheel & Crank Set also means its maintenance requirements are relatively low. Fewer parts means fewer points of wear and failure.
While multi-sprocket systems offer more functionality, they also mean more parts to maintain and maintain. Additionally, more components may also increase the risk of failure.
Therefore, there are obvious differences between the Folding Bike Single Chainwheel & Crank Set and the multi-chainwheel system in terms of design and structure, shifting ability, weight and portability, as well as maintenance and durability. Which system you choose depends on your individual riding needs, budget and preference.
