Does a larger gear number on a bicycle indicate a larger or smaller wheel?

[DeAubree]

The large chainring at the front is the smallest 1st gear, which is the lightest. Shifting to a larger chainring makes it heavier. The largest cog at the rear is the 1st gear, which is the lightest, and shifting to a smaller cog makes it heavier. Introduction to the transmission: The transmission, also known as the gearbox, is an automotive component used to alter the speed and torque from the engine, and can fix or change the gear ratio between the output shaft and the input shaft. Principle of the transmission: A manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. An automatic transmission, on the other hand, is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.
