What Does 21 Speed Mean On A Bike?

What does 21 speed mean on a bike? In a derailleur geared system, bikes are often referred to as "21 Speed" or suchlike. We'll use 21 speed ongoing as it was very very common for quite a long time. If our bike has three chainrings and seven sprockets, we have 3 x 7 = 21 gear ratios. This is what is referred to as 21 speed.

Is 21 gears enough on a bike?

In terms of how the number of gears affects the overall ride of the bike, a 21-speed is generally faster with smoother transitions and pedaling. The 7-speed is adequate for most riders, which is why many people choose the slower option.

Is there a 24 speed bicycle?

You can think of gears as the same thing as speeds – a bike with 18 gears is an 18-speed bike. Bikes generally have 1, 3, 18, 21, 24, or 27 speeds.

    Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.


    How many speeds should a hybrid bike have?

    To get more than seven speeds, most bikes will have to add a front derailleur and an additional chainring or two. The very capable 21-speed configuration is the most common for hybrids, and it delivers a broad range of gears that can handle just about anything.
