So many models/type
When trying to decide on which type of bike you want to ride, think about these question:
•Who you ride with?
•What types of bike they using?
•Where would you like to ride?
If you are buying a bike to ride with a group of friends, buy the similar model/types which they are using. You will not be able catch up your friends if you are using a mountain bike when they are using a road bike.
Road bicycles are designed to be ridden fast on smooth pavement. They have smooth, skinny tires and “drop” handlebars, and can be used for on-road racing. They are usually lighter than other types of bicycles. They can be ridden on paved trails, but most people find them uncomfortable and unstable on unpaved trails. Most road bikes are not capable of carrying heavy loads.
Mountain Bikes (MTB)
Mountain Bicycles are design for riding rough off-road trails. They have flat or upright handlebars, and a very low gear range for pedaling up steep trails. Most mountain bikes have some type of shock absorbers or suspension. Mountain bikes with front suspension only are called hardtails; mountain bikes with both front and rear suspension are called full-suspension bikes or duallies. Mountain bikes with no suspension are called rigid. Mountain bikes can be outfitted for use as touring or commuting bikes, although they would not be as light or efficient as traditional touring or commuting bikes.
Hybrid Bicycles were originally conceived to provide the advantages of both road bikes and mountain bikes. Their large, padded seats and upright handlebars provide a comfortable riding position, and are best for casual riding around the neighborhood or bike paths, short-distance commuting, and errands around town. They can be ridden on paved roads, but are not as lightweight or efficient as road bikes. They are ideal for paved or unpaved bike trails, but are not appropriate for rough off-road mountain bike trails. The tires are usually a medium-width with a semi-smooth tread, to provide a fairly smooth ride on pavement, but enough grip and cushion on unpaved trails. Most hybrid bikes have front suspension to smooth out small bumps, but some are fully rigid.
The term “city bike” doesn’t really refer to a specific category of bikes; it’s more of a general descriptive term. They might also be called “commuter” or “urban” bikes, although many of the bikes listed on this page can be used quite well for riding and commuting in a city. However, there is a certain type of bike that some people have in mind when they use the term “city bike.” This bike has characteristics of both a hybrid bike and a cruiser bike–usually the upright riding position of a cruiser, but the wheel size of a hybrid bike
A city bike might also have some or all of these features that make it more amenable to riding in regular clothes, as opposed to cycling-specific clothing:
•Skirt guard on rear wheel
A city bike might also have an internally-geared rear hub for ease of use and maintenance, and a built-in generator and lights for safety when riding after dark.
Fixed-Gear Bikes or fixies are designed to be ridden on a velodrome, which is a banked oval track specifically for bicycle racing. Some commuters prefer track bikes, however, due to their simple design, which makes them easy to maintain. They have a single gear that does not provide the ability to coast, so if the bike is moving, your feet must be pedaling. For even more simplicity, some riders prefer to not have brakes, since the fixed-gear mechanism can act as a brake. Most track bikes have drop handlebars, but some riders outfit theirs with flat or upright handlebars.
Folding Bicycles are ideal for those who need to travel with their bike, want a bike to keep on their boat or plane, or who live in small apartments and don’t have a lot of storage space. They’re also good for commuters who need to take their bike on a bus or train for part of their commute, or who don’t have a safe place to park their bike at work. Most folding bikes have smaller wheels, which makes the bike a little less efficient and trickier to handle than a standard bike, but most folding bike fans feel the benefits outweigh the disadvantages.
