- 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.
What does it mean when a bike is 21-speed?
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.
Why do you need 21 gears on a bike?
Most bicycles come equipped with gears to help riders tackle various terrains. For example, a 21-speed bike has a triple chainring in the front and seven rear cassette gears. 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.
Is 7 speed or 21 speed better?
If you ride on flat ground or with little slopes, or if you do not care about achieving high speed on flat, go for the 7 speed. But if you want to overcome steep climbs and also have good speed on the flats, then you may need a bike with more gear ratios.
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.
Is 20 mph on a bike fast?
Most cyclists can achieve 10-12 mph average very quickly with limited training. Reasonable experience, medium (say 40 miles): average around 16-19 mph. Quite competent club rider, some regular training likely, medium-long distances (say 50-60 miles): 20 -24 mph.
How many speeds can a bike have?
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.) Lower numbers are the low gears, and higher numbers are the high gears.
What is the fastest 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.
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.
What is the left gear shift on a bike?
The left Shifter controls the front derailleur and swaps the chain between the front chain rings. This type of shifting is for big jumps in gearing for sudden changes in terrain and slope.
Why do cheap bikes have more gears?
Cheaper bikes have more gears because they rely on a basic and mass-produced triple crankset technology naturally resulting in a large number of chainring to cog combinations. Conversely, 1x and 2x drivetrains are more optimized, trendy, and use sophisticated materials and rear mech.
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”.
Is single speed better than gears?
Single-speed bikes are more lightweight than geared bikes. Because of this, they are easier to manoeuvre and use, especially on plain roads. They are a great way to feel the wind on your face as you coast by. Moreover, single-speed bikes are more portable.
