The larger the front chainring, the smaller the number of teeth on the rear flywheel. It is the most difficult to pedal, but the speed is the fastest. On the contrary, the small chainring and the large flywheel are the easiest to pedal, but the speed is also the slowest.
Generally speaking, when we ride mountain bikes, we generally use the second chainring. For flat roads, we generally use 4-5-6 flywheels. You can try this and get the most suitable gear ratio for yourself.
The significance of a variable speed car is to change the gear ratio. The gear ratio does not remain the same during the riding process. Different gear ratios are maintained according to different terrains.
