A 21-speed bike has three front gears and seven in the rear. Each speed on a bike refers to a different combination of gears. By changing the combination of these gears, you can make it more or less difficult to pedal. Despite the number of gears, it is simple to learn to ride a 21-speed bike.

Is a 21-speed bike good?
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.
Why do bikes have 21 gears?
The total number of gears is the product of the number of chainrings you have and the number of cogs on your cassette. If you have 21 gears you have a triple chainring and a 7-speed cassette in the rear. If you have two or three chainrings some of your gears overlap, so they don’t give you more capability.
What does 22 speed mean on a bike?
A triple chainring set-up with a 10-speed rear cassette is therefore a 30-speed bicycle — in other words, it’s possible to use all of the 10 sprockets in combination with each of the three chainrings. Likewise a double chainring paired with an 11-speed cassette is a 22-speed set-up, and so on.
What is 21-speed Shimano?
A 21-speed bike has three front gears and seven in the rear. Each speed on a bike refers to a different combination of gears. By changing the combination of these gears, you can make it more or less difficult to pedal.
Do you need 21 gears on a bike?
Most bikes these days come with ’21 speeds’. However, this doesn’t mean you have 21 useable gears. If you’re going uphill and you need a lower gear, keep pedaling, but ease off and pedal lightly while you shift. Most systems have three gears on the front, which are controlled by your left shifter.
What gear should I use on a flat road?
Middle gear is perfect for regular terrain on flat roads. When you need some strength but not too much to ride on undulating terrain, you can shift your gear to the middle level. For that, you have to combine middle chainring on triple rear cogs to ride on flat roads smoothly.
What is a good average speed on a bike?
The majority of riders can average a speed of about 15 mph on a one hour ride. A good speed for a beginner is 10 mph, but you should be able to get to 15 mph pretty quickly. If you start training every once in a while, you could get your average up to 18 mph, but training on a regular basis could get you to 22 mph.
Does more gears mean more speed on a bike?
Just remember that larger gears at the rear mean easier pedalling but more torque, and larger gears at the front mean harder pedalling but more speed. Going from “easier” gears to “harder” gears is called “upshifting”, and the reverse is called “downshifting”.
What is the easiest gear on a bike?
The low gear is the “easy” gear and is primarily used when climbing. The low gear is the smallest chain ring in the front, and the largest cog on the rear cassette. In this position pedaling will be easiest and the least amount of force will be required to push the pedals.
Are more gears better on a bike?
Broadly speaking, mountain bikes have lots of low gears so you can climb steep hills more easily, while road bikes have more higher gears to boost top-end speed. More gears means more choices, but also more complexity for riders (and shop techs).
What is a high gear on a bike?
High Gear = Hard = Good for Descending: The “highest” gear on your bike is the largest chain ring in the front and the smallest cog on your cassette (rear gears). In this position, the pedaling will be the hardest and you’ll be able to accelerate while traveling downhill.
Is there a 27 speed bike?
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. (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) On three-speed bikes, the gears are inside the hub of the wheel so you don’t see them.
