An exceptionally essential condition required when looking for bikes is the comprehension of measurement and size. For many people, this aspect could be too boring to check, but trust me, this is the most important aspect to consider when buying a bicycle- how comfortably would I fit in? While this method could work out when shopping for a bike at one of the bike shops, it could fail greatly when shopping online for bikes.
Looking through Craigslist for the bike of your dream requires more bicycle information than you might think you have, including a knowledge of accurate sizing. Whenever you are shopping for a bicycle, you are not only shopping for the bike that best goes in line with your riding style, but also for the one that houses your body work comfortably and by that you are looking for the frame size.
Going for a frame that is too small or too big could prompt uneasiness, pain, and injury. In spite of the fact that height is one of the key assessments you will require when you go to the bike shop, many factors are to be considered too when looking for the bike that best fits you.

Get your accurate height at first
In order to get the best bike fit, you have to be precise about your height. To determine your accurate height, all you have to do is stand on the bare floor with your shoes off and your back up against the wall. Your feet ought to be about hip-width separated and you can be measured from the base of your feet to the apex point of your head by a friend.
Since bicycles or bikes are measured utilizing either the metric or U.S. system, record the measurement in inches and in centimeters. In the event that your measuring tape does not have centimeters, multiply your height in inches by 2.54 in order to convert it to centimeters.
How do you measure the size of a bike frame?
Let me shift this to the best of your knowledge – bikes are solely measured based on the size of their frames. So how do they determine the frame size? I know this question popped up but here is your answer, the length of the seat tube is used to determine the bicycle frame, the upright part of the frame that gives support to the seat post and the seat assembly.
However, you have to know that, the comfort of your ride only lies in how perfectly you choose the right frame for your height and thus, this gives you absolute control of your bike. Although individuals vary, if you happen to be between 5 feet 8 inches and 6 feet tall, an 18-inch bike would be an ideal bike for you.
A 16-inch bike would be good for a shorter individual, while taller persons would have more comfortable riding a 20-inch bike. In order to help you measure bike frame accurately, I have assembled few steps that could easily guide you through the process.
- Step 1: The first thing you need to do is to locate the top of the seat tube. The seat post joins or enters the bike frame at this point and the seat post is actually the part where the bike seat is connected.
- Step 2: Here comes the next step, which is to locate the bottom bracket. The bottom bracket is a cylindrical section at the bottom of the seat tube. Pedals are connected to the bike here.
- Step 3: To get the accurate bike’s frame size, measure the length from the top of the seat tube to the center of the bottom bracket that I called the cylindrical section. Whatever measurement you get, is the bike’s frame size.
- Step 4: As some bikes are measured in inches, some are also measured in millimeters. In some cases, a conversion may be necessary, but I will walk you through it. If you are converting inches to millimeters, you just only need to multiply the measured inches by 25.4. And when converting millimeters to inches, divide your measured millimeters by 25.4.
Bike frame size could be a useful guideline for purchasing the right bike. However, sizing a bike takes much more than that. To determine if a bike is right for you; there are three things you are required to look for when you are sitting on the bike. Your foot ought to be flat on the pedal, and your leg will be extended fully when the pedal is at its lowermost point.
When the pedal is at its uppermost point, your knee, in any case, should not come up to the horizontal seat tube. Lastly, check if your feet can touch the ground when the bike is standing. In the event that you cannot amend the seat to a point meeting these three conditions, then the bike is not of your frame size.

Additionally, when choosing a road bike, you can’t afford to get it wrong, in order to ensure this; I have painstakingly prepared a chart for you by which you can see what frame size is best for your height. If you can get your size right, then cycling should be more than fun for you.

A mountain bike is a bike designed to be used for off-road activities. Although mountain bikes share similar features with other bikes they possess their own features, which make them stand out amongst other bikes. They are more durable and have enhanced performance to withstand all the roughness of the terrain by which they operate.
These commonly incorporate suspension on the edge and fork, extensive bumpy tires, tougher substantial wheels, all the more super powerful brakes, and lower gear proportions required for steep grades with poor grip. I had the opportunity to ride one of these bikes some years ago and trust me, they are extremely powerful.
Moreover, mountain bikes are ordinarily ridden on mountain trails, logging streets, fire streets, single tracks and other unpaved surfaces, where an adventure needs to be embarked on. These sorts of landscape ordinarily incorporate rocks, washouts, grooves, free sand, free rock, roots, and soak grades.
From my own point of view, I could see that mountain bikes are manufactured to deal with this landscape and the impediments that are found in it like boulders, logs, and vertical drop off.
Since the introduction of mountain bikes in the 1970s numerous new subtypes of mountain bikes have been developed, for example, cross-country (XC) bike, a bike that is known for its all-day endurance attribute, downhill mountain biking, freeride biking. Each of these bikes places unique requests on the bike needing diverse designs for ideal performance. In addition, MTB development has added an increase in suspension, ordinarily up to 8″ or 203mm, and the gearing system, up to 30 speeds, to aid quick climbing and fast descends.

Hybrid bike size chart
Hybrid bikes generally have a level handlebar, the similar to the one found with a mountain bike, as opposed to the drop bar you would see on a road bike. This implies braking and shifting segments are most times the same as mountain biking units, rather than being STI-style coordinated shift levers and brake as you will discover on all road bikes.
This enables an upright riding position – a position that many of us are comfortable with, and possibly more secure, in traffic. Hybrid bikes additionally tend to use bigger volume tires than road bikes, offering more solace than smaller road rubber. Some hybrid bikes are similar to mountain bikes than road bikes, and others fall closer to the paved area side of things.
Braking can differ from model to model; nevertheless, you will find V-brakes everywhere these days, as are hydraulic disc and mechanical system. According to my observation, hybrid bikes normally offer adaptable gearing; triple chainsets and colossal cassettes are common. There are exemptions, however – hybrid bikes can in some cases get center point gears for close support free mile chomping, although single speed models are also available if you prefer simplicity.
A few hybrids accompanied full curved guards, and much pannier racks, while most hybrids are made with the clearances and eyelets necessary to retrofit such items.

Let me show you how it works: Let’s begin with the 26 x 2.125 size that ended up plainly famous on heavyweight “balloon tire” bicycles in the late ’30’s and still, stays on “beach cruiser” bicycles.
This size of the tire is close to 26 inches in genuine diameter. However, a few riders were disappointed with these tires and needed something faster and lighter. The industry reacted by making “middleweight” tires stamped 26 x 1.75 to fit similar rims. Despite the fact that they are still called “26-inch”, these tires are really 25 5/8″, not 26″.
This same rim size was embraced by the early pioneers of west-coast “Klunkers”, and turned into the standard for mountain bicycles. Because of the craving of the market, you can get tires as tight as 25 mm to fit these rims perfectly, so you end up with a “26-inch” tire that is more similar to 24 7/8″ in genuine diameter.
However, a 26-inch bike is mainly for individuals with 5’0″- 5’3″ heights. A 26-inch bike must have 46 – 48 cm frame size thereby making it a right fit for individuals with 5’0″- 5’3″ heights. Examples of the 26-inch bike include Commencal Supreme Park (2015), Kona Stinky 26, and Rocky Mountain Maiden.
