The relationship between bicycle chainring and flywheel
The relationship between bicycle flywheel and chainring
The bicycle flywheel and chainring are important components of the bicycle transmission system. They are connected by a chain and together determine the speed of the bicycle and the rider's effort. The size of the flywheel and chainring is different, and the riding experience will also be different
Gear ratio relationship
The speed of the flywheel is equal to the chainring speed multiplied by the gear ratio (number of chainring teeth ÷ number of flywheel teeth). This means that the larger the chainring, the smaller the flywheel, the faster the riding speed, but the more effort is required, which is suitable for flat or downhill roads; on the contrary, the smaller the chainring, the larger the flywheel, the slower the speed, but the less effort is required, which is suitable for long and steep uphill roads.
Power transmission relationship
The size of the chainring and flywheel directly affects the transmission of power. A large chainring means that the rider transfers more force to the chain every time he pedals; a small flywheel means that the same force can make the wheel turn faster. On the contrary, if the chainring is small and the flywheel is large, although the speed is slower, the rider can ride with less effort.
Speed change relationship
In actual riding, riders will adjust the difficulty and speed of riding by changing different chainrings and flywheel combinations according to road conditions and changes in personal physical strength. For example, when going uphill, a smaller chainring and a larger flywheel are usually selected to reduce pedal resistance; while on flat roads or downhill, a larger chainring and a smaller flywheel are selected to increase speed.
In summary, the relationship between bicycle flywheels and chainrings is mainly reflected in three aspects: gear ratio, power transmission and speed change. Riders can adapt to different riding environments and personal needs by adjusting the combination of the two.
