Bicycle strucure

bicycle

Bicycle consists of multiple part groups – frame, that holds everything together, fork that absorbs impacts on the front wheel, drivetrain, wheel set, seat and seat post, stem and handlebar. Each part of bicycle holds an important role in bicycle structure and how the ride on the bike feels. Bicycle parts can cost from under dollar for smaller bolts to couple of hundred or even thousand dollars for large and expensive parts like frame and fork.

Each type of bicycle has different parts. For example bmx bikes have smaller frame and wheels, rigid fork, high rise bar, strong and heavy stem, only one speed, stronger cranks and rim brakes. In opposite, a mountain bike will have different type parts. Mountain bikes have larger frames, often made from aluminum alloy, suspension fork to absorb impacts on the front wheel, aluminum handlebar and stem, multiple speed gear with shifters, derailleurs and special chain guards. Mountain bikes usually have disc brakes instead of rim brakes, but also rim brakes are used on mountain bikes. Disc brakes are used more often, because they do not lose braking power in rain and mud. All bicycles, except special trail bikes used in sports, have seat and seatpost. Seat is chosen in matter of comfort level rider want. For cruising rider will choose softer and larger seat, for longer distances a more lighter and comfortable seat. For sports the lightest and durable seat possible, as there is no need for comfort. Handlebar and stem are also different for each bicycle type. Main type of handlebars used on most mountain bikes are aluminum alloy bars with little or no rase. Road bikes have special handlebars types called bull horns. On bmx bike you will see a high riser bar that is durable and made specially for racing and tricks. On bicycles used for downhill you may also see chromoy and carbon handlebars.

Frame and Fork

Bicycle frame is made from aluminum or chromoly. You will find aluminum frames on many mountain bikes and chromoly frames on bmx bikes. Frames comes in many different sizes, the size of frames is measured in inches. Bicycle frame manufacturers are making frames from size XS to XXL similar as with clothes. So if you are an average height person, you will need a M size frame. Forks are also made for different bicycle types. Some bicycles like bmx, roads, fixed gear and some mountain bikes will have rigid forks. Rigid fork do not absorb impact on front wheel, but allows rider to accelerate faster and do not waste so much energy while pedalling. Suspension fork is much more comfortable, but also more heavier. This means that suspension forks are not used in cycling sports, where bike weight plays an important role. Suspension forks comes with different travel lengths. Forks used for riding in city will have 60 – 80 mm travel and forks used on tracks, in woods or on mountain will have fork travel from 100 – 180 mm and more.

Brakes

There are also multiple types of brakes. The most popular brakes on bmx and fixed gear bicycles are rim brakes. Rim brakes are braking bicycles rim with special rim brake pads. Mountain bikes mostly uses disc brakes. There are two types of disc brakes – mechanic and hydraulic. Mechanic disc brakes are the most basic version of disc brakes and are used on mountain bikes that do not need that much braking power. Hydraulic disc brakes works with oil pressure, similar as car brakes. Hydraulic disc brakes are used on high end mountain bikes. Hydraulic disc brakes can be found on most xc and downhill racing bicycles.

Wheels

Wheels used on bicycle mainly differs in size. Smaller bicycles will have smaller wheels, as bmx, and larger bicycle will have larger wheels, as road and fixed gear bikes. Average wheel size for mountain bike is 26 inches, for bmx 18 inches and for road and fixed gear bikes up to 29 inches. There are also 29 inch mountain bikes or 29ers that are becoming more popular in past few years. Most types of bicycles used freewheel hub, but fixed gear bicycles uses fixed gear hub. Freewheel means that bicycle movement does not move cranks and pedals. Fixed gear hub means that movement of bicycles back wheel is also moving the cranks and pedals.

Little bit about bicycle history

Beginning of bicycles

Bicycle was invented before more than 100 years and since then has evolved into one of the most used means of transportation. Bicycle is simple, yet quite fast way to get from one place to other. First bicycle did not have any pedals, they were made from wood, and you couldn’t go fast with wooden bicycle. After some years first metal bicycle were built. These bicycles had metal wheels, but did not have pedals, so they were not a huge improvement over wooden bicycles. After some time pedals were invented. Pedals where attached to front wheel and rider did not reach high speeds with that kind of bicycle. Next bicycle type was with large front wheel and small back wheel called Penny Farthing. As fun as it sounded, it was actually pretty dangerous bicycle, and it was pretty easy to crash with this bicycle. These types of bicycles were faster than previous bicycles and also looked nice, so many people rode with them, despite the danger of falling of the high bicycle and hurting themselves. Next bicycle type obviously had similar front and back wheel, so riding it was much more easier and safer. Before this bicycle type was invented, one huge invention was made, that changed all bicycle industry – pneumatic tyre. This way bicycle riding was proved significantly, allowing bike rides to feel more comfortable on bicycle and reach higher speeds with a bike.

In next 30 – 50 years bicycle manufacturers just improved their bicycle technologies. Bikes were made a lot more stronger and faster. With first types of bicycles rider could no go much faster than walking, but after 50 years of bicycle manufacturing, bicycles were one of the most popular means of transportation. Many people that did not have cars, or could not afford them, used bicycles as their main transport to get from one place to other. Bicycle was perfect for cities, as it was easy to ride to any place in the cities. Bicycles were also used in war. They were useful, because soldiers could go faster with bicycles than they could walk or run, and also go further distances. And bicycles allowed to carry more bags or ammunition with them. War bicycles were really tough and heavy and soldier could ride many hundred miles with those bicycles and they did not break and were usable for many years. Also speeds were invented at that time. Before that, bicycles has only one speeds. These types of bicycles are called single speed bicycles. First speed bicycles had 2 or 3 gears. This allowed rider to ride faster uphill. Old bicycle speeds were not like our bicycles today. Their speed shifters were located somewhere on the frame and shifted front gear, not rear. Old bicycles did not have v-brakes or disc brakes. Instead they braked by locking their feet and blocking rear wheel. Those older bikes did have fixed gear cogs, so braking was similar as today with fixed gear bikes. Women bicycles were also a hit, when they were invented. Women bikes were made for comfort and beauty more than for riding further distances.

40s bicycle

In 70s, 80s and 90s new bicycle types were invented. Mountain bicycle is the most popular bicycle now. In those years first suspension forks were used on bicycles. This also changed bicycle manufacturing and riding a lot, and now bicycles could be ridden off road with lot more comfort. New sports disciplines like cross country and downhill begin. Also different bicycles for tricks and jumping were invented like bmx and trial bicycles. As popularity of extreme sports grew pretty rapidly, these types of bicycles also progressed fastly and pushed all the industry to make lighter, stronger and faster bicycles. New materials were used for bicycle part building like chromoly, aluminum and carbon. New materials were first used for sports bicycles like racing, bmx and trek bikes. After some time materials used to built race bike parts were also used on mainstream bicycles. In 21 century bicycle manufacturing did not progress as fast as before, but racing and contest bicycle were improved year by year. They were made a lot more lighter, parts were stronger and price for bicycle with good and strong parts also got more appealing to regular people that wanted to ride with durable and good quality bicycle.

Today progression of bicycle manufacturing is much more slower, and companies are inventing new bicycle technologies much less than it was before. However, each year newer and better bicycles and bicycle parts and accessories are coming out, and there will be progression in bicycle manufacturing as long as we will ride bicycles as much as we do now.
