The large number of sizes, types, and types of bicycles that exist today makes buying the right bike feel like a tough job. The good news is that the most important thing in choosing a bike is not mere size numbers, but also your comfort. By knowing the basics about bicycle parts and sizes, you will be able to choose and buy the bike that is right for you after one or two tries.
Step
Method 1 of 3: Buying a Road Bike
Step 1. Buy a road bike if you will be riding a lot on paved roads
There are several types of road bikes with different styles and functions. Overall, however, road bikes are designed to be ridden on rough or smooth city streets. Road bicycles are the most common type of bicycle. Some of the derivatives of this type of bicycle are:
-
Racing/road bikes:
aerodynamic, fast, and lightweight, this bike is the most commonly used type. With thin tires and a lightweight frame, these bikes are usually not designed to carry heavy loads. The components are designed for fast driving on a wide variety of surfaces, from uphill valleys to long horizontal roads.
-
Cross bikes (Cross bikes):
With a stronger frame and wider tires, this bike is designed to ride on a variety of surfaces, from city streets, bike paths, to trails. This bike is also designed to carry heavier loads and works well for commuting to work, the shop or other short distance trips.
-
Tour bike:
With a sturdy frame and minimal knickknacks, this bike is designed for long-distance travel, is self-sufficient, durable, and can withstand heavy loads. With these properties, this bicycle is also suitable for use as a commuter or city bicycle.
-
Triathlon bike:
sold for a high price, this bike is designed to be ridden at high speeds, has a very light weight, and special handlebars that allow you to crouch very low while riding to minimize air resistance.
Step 2. Learn how to measure a bicycle frame
The main factor to consider in buying the right bike is the frame size. The frame is the metal body that supports the bike. Frame measurements are made on three key sections. Although most bicycle manufacturers only use the size of one part as a benchmark for scale, knowing the size of the three parts is key to getting the right bike size.
-
Seat Tubes:
vertical bar that fits between the saddle and the pedals. Its length is measured from the center of the crankshaft (the disc on which the crank is attached).
-
Top Tube:
horizontal bar between the saddle and the handlebars. This section is connected with the reach of your hand to the handlebars.
-
Head Tubes:
The vertical area on the front of the bicycle, measured from the front fork or bicycle fork to the base of the handlebars. This part also affects your reach to the handlebars.
Step 3. Measure your body's inseam
Stand with your feet 15.3 cm wide, then measure the distance from the inside of your feet to your pubic bone (the point where your feet meet your waist at the groin). Record the size of this section in centimeters because all road bikes have this unit of measure.
Step 4. Multiply the inseam size by 0.67 to estimate the seat tube length
Use the multiplication results to determine the seat tube size that is right for you. For example, if your inseam measures 85 cm, the right seat tube length for you is 85 cm × 0.67 = 56.95 cm or 57 cm.
The seat tube length is usually (not always, but often) measured from the top of the rod to the center of the crankshaft
Step 5. Make sure you can stand comfortably with the top tube between your legs
On the street, you'll stop at a red light, and you'll need to be able to stand with both feet on the ground while you wait. Clamp the bicycle with both feet and make sure you can still stand with your feet on the ground. If you can't do that, you should choose a bike with a lower frame size.
Step 6. Try different types of bikes to determine your range
While there are currently many calculation formulas that can be applied to determine the right range, at the end of the day, everyone has a different range, and you will have to decide for yourself which size is right for you. When you try to ride a bicycle, pay attention to the length of the top tube and head tube, as well as the length of the base or stem - the small part that connects the handlebars to the frame - then write down the size that suits you as a benchmark if you are going to buy a bicycle in an online store. A comfortable range should be:
- Allows you to reach the handlebars comfortably. Your fingers should be free to wriggle on the handlebars.
- Allow your elbows to bend slightly instead of sticking out straight or pressing down.
- Allows you to reach all parts of the handlebars, especially gear shifts and brakes, with ease.
Step 7. Know that comfort should take precedence over size
The length of each rod may be of little significance to the final size that is right for you. This is because the angles of the frame connections will also affect the distance between the saddle, crank and handlebars. For example, studies have shown that a longer top tube can provide the same level of precision as a short top tube as long as the length of the head tube is adjusted accordingly. While these numbers are a good starting point when you're about to buy a bike, they don't mean you have to follow them all the way to get the right bike.
Always ask to try three to four bike brands, and always try bikes one point above and below what you've measured. Everyone's body geometry is very unique, and because of that, you have to find the perfect bike for your body
Step 8. Buy a road bike with the same height as the saddle if you are a beginner
It's very easy, especially with the downward curved handlebars, to lower the hand height on the bike. While experienced riders tend to prefer lower handlebars, riders with flexibility issues or just getting started with cycling will almost always prefer a bike with the same height as the saddle.
- Flat-shaped handlebars are rare on road bikes that aren't designed for cruising or casual travel. It is very difficult to drive long distances with flat handlebars.
- The curved handlebars are classic dual C-shaped handlebars with two forward-facing brakes and various types of arm mounts for added comfort.
Step 9. Purchase a rack if you plan to travel long distances or commute on your bike
Bike racks allow you to pack things on the rear tires. However, not all bikes are rack compatible. In general, road bikes are not designed to withstand the weight of a rack; on the other hand, touring and cross bikes can. Rack-mountable bikes have two holes above the v-shaped section of the frame that connects the seat to the rear wheels and two more holes at the very back of the frame.
A basket is a box specifically designed to attach to a bicycle rack, and is an essential item to have if you carry a lot of stuff or want to travel long distances
Method 2 of 3: Buying a Mountain Bike
Step 1. Buy a mountain bike if you want to ride on rough terrain instead of cycling at high speeds
Mountain bikes are designed for tough terrain. Due to its design, mountain bikes can go through trails, rocky and muddy trails without any problems. It also makes people who live in big and small cities like it. However, mountain bikes are still designed to face rocky trails, roots, ups and downs, safely.
- A trail bike is a type of mountain bike that can tackle light, heavy trails, and paved and rocky roads quickly.
- All mountain bikes are designed for tough trails, technical and experienced riders.
- If you're planning to try a mountain bike, a little extra cash is worth it for comfort and safety.
Step 2. Use the inseam size to determine the correct frame size
Standing with your legs open 15.3 cm apart, measure the length from the inside of the leg to the point where the thigh meets the waist, between the groin and the inner thigh. Multiply this number by 0.67, then subtract 10, 16 cm or 12.7 cm to get an estimate of the top tube size that is right for you. Use the top tube as your benchmark whenever possible because the seat tube (length from crank to saddle) is often difficult to determine and varies in value from manufacturer to manufacturer.
-
If your inseam is 84 cm, for example, you will need a top tube that is 46.12 cm high because:
84 cm × 0.67 = 56.28 cm
56, 28 cm – 10, 16 cm = 46, 12 cm
- Specialty bike manufacturers like Lapierre & Neil Pryde have different geometry benchmarks. Multiply your inseam size by 0.62 instead of 0.67 if you want a bike made by the manufacturer.
- If the bike shop you're visiting lists the length of the seat tube as your frame size, multiply your inseam by 0.185. The right bike for you will have the same length from the top of the seat tube to the center of the crankshaft as you multiply it.
Step 3. Always prioritize comfort over size calculations
Since the angle of connection of the rods to the frame also affects the distance between the saddle, pedals and handlebars, these measurements will also differ from one bike to another and from one rider to another. Studying sizing is a great starting point, but in the end, you'll have to choose the bike that you feel most comfortable with. Try on different brands and sizes above and below the size you've already measured. You will have to try on more than one bike to find out and choose the right size for you.
- Your hands should be able to reach the handlebars comfortably in such a way that your fingers also feel free to move.
- Your elbows should be slightly bent instead of sticking out or pressing against the handlebars.
- Most mountain bikers tend to choose handlebars that are 2.54-5.08 cm lower than the saddle in order to lower the center of gravity.
- The right bike will allow you to reach for gear and brake changes without losing your balance.
Step 4. Choose between single or double suspension
All mountain bikes have vibration dampers on the front tires. The goal is to face obstacles and maneuver easily on uneven surfaces. However, experienced cyclists tend to consider using dual suspension:
-
Hardtails:
another name for single suspension, hardtail bikes only have suspension on the front wheels. This bike has a lighter weight, a cheaper price, and is also suitable for riding on paved roads.
-
Full suspension:
Designed for tough and technical trails, these bikes are heavier but much easier to maneuver and are useful for more experienced mountain bikers.
Step 5. Look for a bike with a frame designed for larger wheels for greater comfort and ease on tough trails
Now, larger wheels tend to be more preferred. The drawback is that you cannot replace it with smaller wheels if the frame is designed for large wheels. In general, you have three options for tire size:
-
73, 66 cm:
This one big wheel is suitable for cruising over rocks and forest soil, has a strong grip on the surface, carries momentum well downhill and allows you to go faster, but it's hard to accelerate.
-
69, 85 cm:
This hybrid wheel has the same speed as the classic 66.04 cm wheel with the same movement capability on rocks and soil as the 73.66 cm wheel.
-
66, 04 cm:
traditional wheel size, designed to be light weight, high speed and to function well on uneven roads. Until five to 10 years ago, these wheels were still the standard for mountain bikes.
Method 3 of 3: Choosing the Right Bike
Step 1. Buy a bike that fits you and allows you to level up your skills
Bikes don't come cheap, and you don't want to have to buy an extra bike just because you don't think the first one is good enough. If you're really serious about cycling for mountain riding, road trips, touring, or for commuting, spending a little more on a single purchase will save you money for the long haul. Ask yourself: how good is your current level of fitness? How far do you want to improve it? You should choose a bike that is between these two points.
- Beginner or intermediate level cyclists should start with light trails that do not require large suspensions. However, if you like cycling, you'll quickly want to try trails that are heavier and require better suspension.
- Road cyclists may have enough with heavier, cheaper bikes. However, as you get more experienced, on the same bike, you won't be able to take part in group riding or touring very well.
- The frame is the most expensive part of the bike. Therefore, this section should be the first thing you think of. Brakes, gears, wheels and handlebars can be replaced or upgraded at a later time. However, you should still choose a bike with good components that are resistant to natural factors, abrasion, in order to get a better riding experience.
Step 2. Choose a comfortable cruiser or hybrid bike if you only want to use it for occasional city rides
These types of bicycles are available in various functions and sizes, but the main design remains the same: they are not intended for long-distance riders. If you feel that a mountain or road bike is too specific for you, try this type of bike. Typically, cruiser or hybrid bikes are sold in standardized sizes: S, M, L, and XL. Choose a size that allows you to reach the handlebars comfortably. Your knees should also be slightly bent when you're fully cranking your bike.
-
Fixed gear:
this type of bike is light in weight and has a simple build, made almost entirely for city riding without extra gear. Easy to maintain and ride, these bikes are best suited for use on flat surfaces.
-
Cruisers:
Also known as beach bikes or leisure bikes, their build is designed for comfort, with high handlebars that allow you to ride them upright.
-
Hybrid:
a great type of bike for commuting or city riding, the hybrid category has larger wheels than a road bike and has the same geometry as a road bike, making it light and agile while still allowing you to traverse uneven roads with ease.
Step 3. If possible, try the bike in person before buying it online
Buying a bike at an online store is a great way to get the right bike for you while saving money. However, you shouldn't buy a bike online if you haven't tested it before. Once you've narrowed your search down to three to four types of bikes, call your nearest bike shop and ask if they have any of those three types in their area. Go to the store and try to determine which bike is right and comfortable for you before buying it.
User reviews are a means to rate a bike. Check blogs and online bicycle magazines and read what they have to say about a particular bike. Also, look for buyer comments on online sites to find out if there are specific problems with a particular bike that you should avoid
Step 4. Understand the gear ratio
The gear system on a bicycle may seem confusing. However, you should keep in mind that, at its core, the system is based on only two factors: firstly, a higher gear gives you more choice in driving, allowing you to get the right resistance for going up or down sloping roads. However, the presence of gears will also add to the weight of the bike, an undesirable factor if you are a cyclist or mountain biker who goes uphill more than downhill while riding.
- The classic gear arrangement for both road and mountain bikes is three in the front and nine in the rear, resulting in 27 speed bike.
- The compact crankshaft has a smaller gear size and is lighter at the front, with only two chainrings, but with a much lower weight.
Step 5. Understand the types of brakes available
There are two main brake subdivisions on bicycles: rubber brakes and disc brakes. Almost all mountain bikes-except for the cheaper mountain bikes-use disc brakes, while road bikes can use both.
- Rubber brake available in various forms. However, in general, the way it works is the same, namely by clamping the wheel and holding it down to reduce speed. There are two rubber clamps on the right and left sides of the tire that will close when you pull the brake lever. These types of brakes are available at a lower price and are easier to maintain and repair than disc brakes.
- Disc brakes works by means of a metal disc attached to the tire. When you pull the lever, the brake will clamp the disc to slow down the entire tire. Disc brakes are often more sensitive than rubber brakes. The space between the brakes with very narrow discs prevents gravel, leaves, and other foreign matter from getting into the system and interfering with the braking process. However, disc brakes are more difficult to maintain and calibrate.
