The number of gears a bike has is figured by multiplying the number of front chainrings by the number of gears in the rear cassette.
How do gears work on a bike. Once you learn to master the gearing of a 21 speed bike you ll be able to enjoy longer rides that leave you less tired. You can t know the gear range of a bike by the number of gears it has. It s true that a bike with more gears often has a wider range than one with fewer gears but not always and even if it does you don t necessarily need the widest gear range possible. Part of the problem of a hub gear is that it adds weight at one end of the bike which can lead to unbalanced handling.
Bikes have two sets of different sized gears on the wheel you pedal and the back wheel. There s no use in buying. Consult your bike shop at the time of purchase on how yours work or simply jump on your bike make sure to pedal and push your shifters to get a sense of how they function. Instead a gearbox is integrated directly into the frame with the weight.
For example a 21 speed bike has a triple chainring in the front and seven rear cassette gears. A bike with 30 or more gears is not an indication of a machine designed to break the land speed record any more than a bike with only a single gear assuming similar ratios. Cycling gearing can be confusing. This video simplifies all the terms and explains how your gears impact your riding.
