What are the Different Types of Bikes?
There are many different types of bikes made for different purposes. Here are a few most popular ones:
Gravel bikes/Road bikes:Smooth terrains, such as roadways and bike lanes, are ideal for road bikes. They are usually lighter in colour. Their handlebars are twisted, and their tires are narrow. Unpaved trails and rocky terrain are no problem for gravel bikes.
Mountain bike:If you want to ride in varied or off-road terrain, a mountain bike is the way to go. Mountain bikes have flat handlebars and large tires, with suspension for improved grip and comfort on higher-end versions.
Trail / Hybrid bicycle:All other bicycles are included in this category. They're a cross between mountain and racing bikes, with an emphasis on comfort and low upkeep. It may be utilized for leisure purposes, as well as commuting or errands, depending on the model's qualities.

Different sizes of Bikes for Different Purposes
There are various factors to consider before purchasing a bicycle. The first stage is to determine the sort of bike you want to utilize, which is determined by the terrain you intend to ride on.
There is no such thing as an all-purpose bicycle from this standpoint. The bike model, price, and quality you choose should be based on your riding style, estimated miles, and preferred terrain. Below are a few criteria to choose the bike:
- Type of bike: Mountain bike, cross bike, trekking bike
- Material and the quality of used components for the frame of bikes.
- Size of bike frame in accordance with the height of the user
- Various components used in bike
- The ratio of the price of the bike to the quality of components of the bike
Choosing the improper frame size or properly setting the seat post can dramatically reduce your comfort during the ride and, in the long term, cause back discomfort and other issues.
How to Measure Bike Size and Find your Inseam Manually?
To determine your appropriate bike size, first, measure your inseam (the length of your inside leg). Simply put, the inseam length is the distance between your crotch and the floor. So, how do you accurately measure inseam?
- Stand with your feet 6-8" (15-20 cm) apart, close to a wall.
- Sit in the saddle by placing a thick, hardback book between your legs.
- Make a mark on the wall where the book's spine meets the wall.
- Take a measurement from that point to the floor to determine your inseam.
According to the inseam, we can calculate the frame size. The distance between the top of the seat tube (where the seat clamp secures the seat post) and the centre of the bottom bracket is commonly used to determine the frame size. The first point is sometimes chosen to represent the centre or top of the upper tube.
Bike frame size can be calculated using inseam & following formula:
City/trekking bike frames
The frame size of the trekking bike = inseam × 0.64
Road bike frames
The frame size of a road bike = inseam × 0.67
Mountain bike frames
The frame size of a Mountain bike = the Frame size of a road bike - 11
Note: Here all measurements in the above formula are in cm.
Solved Example on What Size Frame Do I Need?
Example:
What frame size do I need if I want to buy a road bike if my inseam is 79 cm?
Solution:
For a road bike, use the road bike frame size formula ie.,
Size of road bike = inseam × 0.67
= 79 × 0.67 = 52.93 cm
According to the answer calculated above & reference to the bike frame size chart, we can say that we can select a frame size of 51 cm to 54 cm for a road bike.
