One of the main features of Brompton urban bicycles is that users can create unique models by customizing and changing the parts of each bike. However, there are four basic Brompton bicycle models that can be distinguished mainly by the height of the handlebars and the saddle, and its aesthetic look.
Brompton bicycle model M
This is the most popular model. The handlebars are high in order to allow users to keep their backs straight while riding. Most of the weight falls on the rear axis, so the steering is not too loaded and the Brompton bicycle M is one of fastest models.
The frame is low to ensure that short people have no problem when riding them. However, people taller than 1.80 m should use an extended seatpost that should be 60 mm longer which adds 105 g to the weight of the bicycle and increases the height of the folded bike by 60 mm.
Another option for tall people is the telescopic seatpost which can be 175 mm higher than standard seatposts and add 364 g to the weight of the bike, but it only increases the height of the folded bike by 20 mm.
This is the model that was actually designed for taller and heavier users who are not comfortable with the aforesaid extensions.
In this case, the distance between the saddle and the handlebars is 57 mm higher than in model M, while it only adds 160 g to the weight.
It looks more like a racing bicycle (a professional sports bicycle) but the handlebars are lower than those in model M (exactly 80 mm).
Those who prefer this model but are too tall can always choose to have double height or extendable handlebars.
This is the most practical but also the less good looking model. The handlebars can be adjusted to multiple positions depending on our needs.
Based on these models of Brompton bicycles you can customize your bike by choosing your favorite color and adding as many accessories as you want in order to own a unique bicycle.
First, let´s mention exactly what an electric bike is and what its components are. Although they are increasingly popular in our society, it is still difficult to find them riding around the city in some areas of Spain.
Well, an electric bike, also known as e-bike, is actually a bicycle with a built-in electric motor that helps it move forward. The bike is powered by a battery that can be recharged through an electric network and its autonomy can range from 35 to 70 kilometers.
Thanks to these advantages, their market has grown and there are numerous manufacturers. This makes the process to select a make and a model more difficult. Therefore, today in Linked2Play we will share with you the key aspects you should bear in mind when choosing an electric bike:
Make sure that, for legal purposes, you purchase an electrically assisted pedal cycle and not an electric moped, which is something different. You do not need a driving license to ride an e-bike and, unlike electric mopeds, its use carries the same responsibility than the use of traditional bicycles.
The rated power of the motor should never be more than 250W because it would be considered a moped.
The maximum speed should not be more than 25 km/h.
It should have front and rear brakes, front light and rear reflector.
You should start the motor only when pedaling and stop it when you stop pedaling or when you apply the brake.
The weight should be less than 40 kg.
You should try once and again which e-bike is more comfortable for you because there may be a lot of differences based on their ergonomics and on personal preferences.
Go out for a ride and test the difference between the electric bikes that need a ride or two before the motor starts assisting the pedal. This will help you decide which mechanism feels safer.
Bear in mind that if the selected model is crank drive, the motor will be located in the bottom-bracket spindle. They have a better design but the main disadvantage is that if a component breaks down, the whole unit must be replaced and that would imply a higher cost.
Choose the bike that better suits you depending on the areas where you will ride it, that is to say, if you are riding on mountain areas, you should buy a model that tries to level out the slopes in a reliable way and vice versa.
The weight of e-bikes also influences the power they should have to offer a better experience. Therefore, you should pay attention to one of the heaviest parts: the frame. Depending on what you will use the bike for, we recommend:
Aluminum 6061 alloy frames: For moderate off-road use and to use them in cities.
Aluminum 7005 alloy frames: For road bikes and urban use.
Steel frames: Intensive use. They are highly resistant and much heavier than aluminum frames.
On the other hand, motors are the second heaviest part of e-bikes. There are two different types: motors with brushes and brushless DC motors. The first type is heavier and noisier, but they are also cheaper. The second type is smaller, lighter and more silent, but they are more expensive.
Finally, let´s talk about the batteries. In order to buy the ones that better fit the use intended for the bike, we should think of the usual roads we will ride on. To calculate the autonomy and energy capacity of the battery, use the following formula:
Autonomy (in km) =Volts x battery capacity in Amperes-hour
x Max Speed / Motor Power
Battery Motor Power Max Speed Autonomy
36v-10ah 250 W 25km/h 36 x 10 x 25 / 250 = 36 km
24v-8ah 250 W 25km/h 24 x 8 x 25 /250 = 19 km
Lead batteries: This is the oldest technology, although they are still used because they provide more autonomy. They are cheaper – from 100 to 120 Euros-, they are also heavier and as an average they only last one year.
Nickel batteries: They are more expensive than lead batteries – from 150 to 300 Euros- and provide less autonomy, but they last 3 to 4 years. It is better to discharge them completely once a month to avoid the storage effect, phenomenon through which they lose their capacity when submitted to irregular charging cycles reducing the bike´s autonomy.
Lithium batteries: Like nickel batteries, they last around 3 years, although they are more expensive – from 300 to 400 Euros. They have two advantages: they have less storage effect and weight less than nickel batteries. The fact that both lithium and nickel batteries are lighter increases the bike´s autonomy making it equal to that offered by lead batteries.
Spare parts are important
Users should take into account the spare parts offered by the shop where they buy the electric bike because some of them – those related to the battery, for instance – cannot be found in regular shops. Thus, shops should have a stock to cover the needs of customers. On the other hand, motors of electric bikes are simple and do not require any special care. Maintenance of e-bikes is as simple as that of any other bicycle – cleaning, greasing, etc. -, so users can save money if they learn how to do it.
Therefore, these are the main points to bear in mind when shopping for an electric bike. Always remember to choose them depending on the use and functions you prefer.
Where can we buy them?
Now, where can we buy them? We can visit specialized off line shops or reference second hand websites such as:
An electric bike is a type of electric vehicle based on a traditional bicycle to which has been added an electric motor to assist in advancing the same. Its power source is a battery and autonomy is between 35 and 70 km, with an average of ecological and urban transport.
The history of the electric bike began in the mid-nineteenth century with the appearance of the first battery, however it was not until the 1980s when it really began to develop.
The idea of producing electric bicycles was in the minds of the industry in the 20s, but competition from internal combustion engines built bicycles gave them more speed and autonomy that it had been an electric battery, shattered their plans.
The 80s was of great importance for the history of electric bikes because in those years the first patents to Ogden Bolton Jr., who sought to implement a bike battery with 6 poles and brush collector current is given (CC ) direct hub motor mounted on the rear wheel, Hosea W. Libbey which created a bike powered by a dual electric motor, and John Schnepf, who introduced a roller wheel friction wheels, which consisted of a rotating roller in the top of the wheel so that this also revolve.
In 1920 the German company Heinzmann made the first electric bicycle motor was two seats. Then he continued to develop engines that joined the German distribution Bicycle mail.
In the 30s, Minneapolis Lejay Manufacturing register patents that are the seed of GoBike, an electric bike with a Ford T generator coupled to the rear wheel.
Later, Moulton Consultants Ltd which manufactures a double chain drive, one coming from the bottom bracket and another electric motor housed inside. However, it is not until the first oil crisis, when it begins to promote the use of electric bikes though they had much popularity.
A late 90 different models of torque sensors and power control, as well as new types of longer lasting batteries are developed. In 1992 Vector Services Limited sells Zike, a bicycle including nickel-cadmium, and whose production grew from 1993-2004 at an estimated 35%.
In the early twenty-first century begins a new modern world for the history of electric bicycles. Panasonic built the lightest electric bicycle market, Honda Step Compo test its, the first folding electric, and again employs Panasonic Lithium ion batteries to revolutionize the market.
Electric bikes are still writing their own history because every year new technology that achieves more people bet on this alternative vehicle is incorporated.
The government of François Hollande has received the green light from the National Assembly in its ambitious Energy Transition Tuesday, something like the new Barcelona’s law about electric bycicles. In the outline of the law, which foresees halving energy consumption by 2050 and make France the European champion of ecology, have added new measures of symbolism. Among them, make it easier for companies to remit money to their employees to use the bike to go to work, at 25 cents a mile, approximately, but not yet priced.
In return, these companies will be reduced social contributions. Companies over a hundred employees will have to submit a plan to promote public transport, car sharing or cycling. Plastic bags single use shall be prohibited from January 2016, but the cutlery and crockery of the same material from 2020.
Promoting cycling has become in France, and more specifically in Paris, a priority. The capital reserve provides growing space to park your two-wheeler and companies-workers- will take advantage if its use promoted. Transport, responsible for 27% of the emission of greenhouse gases, will be much cleaner in a few years in France thanks to the Energy Transition Act which launched Ecology Minister Segolene Royal.
In addition to the seven million outlets will be installed (there are now only 10,000) in 2030, individuals will benefit from a premium (that can reach 10,000 euros) if you change your diesel car for an electric one. The state fleet must be renewed with such vehicles at a rate of one in every two new buy and transport companies, one in ten.
The law, which was approved by a large majority in the Assembly (314 votes to 219), plans to increase renewable up involving 40% of the total, reducing the use of fossil fuels by 30% in fifteen years, renew buildings to save energy and reduce waste by half by 2025. in this last chapter the ban on plastic bags for single use is framed and, depending on demand from environmentalists Assembly, has also added veto crockery and cutlery from the same material. Royal, who was not in favor, has always accepted to enter into force in 2020. Also with an eye toward reducing waste, France plans to penalize up to 300,000 euros and two years imprisonment planned obsolescence. Most products should inform the consumer about their working lives. This, though, will live with the great French nuclear power, which is limited to the current level.
After several years of work on this issue, the Government has confirmed that French households spend too hot. To reduce the bill that entails, the law passed also provides significant support to the most modest to the so-called check-energy, to renovate buildings. The project is to increase the efficiency of buildings 500,000 each year from 2017. The intention is that all the buildings have been renovated in France 2050. A tax benefits aid and cheap loans to achieve this goal are added.
The Senate must now validate the law passed, but will do in a single reading and then the Assembly will give the green light by summary procedure. The main obstacle that critics see in this project is its cost: € 10,000 million in three years. Royal, however, says that the new green economy will create 100,000 new jobs and reduce energy bills.
Like all major brands, the brand of Brompton hides a great story at its source. Its inventor was Britain’s Andrew Ritchie, a gardener by profession who decided in 1976 to start building a folding bike. After graduating from Cambridge in 1968, Andrew worked for a short time in computation, before becoming a landscape gardener and go door to door offering their services.
The British met an Australian accountant who was trying to build a factory to produce Bickerton folding bicycle. When the gardener saw the characteristics of this product, he told himself that he could improve it. The concept was not new, it already existed on the market several folding bicycles that were very successful for the need of people to transport bicycles in the city. However, trying to models made for mass consumption so the quality and usefulness seemed insufficient for many people, including Andrew Ritchie himself.
Its objective was to design, develop a couple of prototypes, and sell the production rights to a company with enough experience to start production. Being a gardener lower middle class, could not finance his project, so he sought help from his friends. They supported him in his idea and together they founded the company “Brompton Bicyles” in honor of the famous London church, Sacred Heart of Mary, but that is popularly known as Brompton Oratory. Andrew was very religious and devout, and also from home could see the church so I wanted his new project bearing the name of the temple. Thus, he turned his room into a studio and started building the first prototypes. Despite the good start and have developed three prototypes, when he sought a manufacturer for design encountered many difficulties that prevented his dream came true and left their idea into a book for five years.
British manufacturers were wary of inventors and were not sure that there was a market for these bikes so they did not want to risk it. “I thought it was a terribly useful machine. Yes, I knew I could improve and all, but really wanted to go ahead with the project because it was a good product, “says the same Andrew at that time.
Five years later, Andrew reprized his invention. This time 30 friends helped to fund and build the first Brompton bicycles. In 1981 thirty units were ready for their first owners. Thereafter demand no longer yield.
The design, a unique model with a curved main tube that makes it unique and allows its folded by a hinge, was well received among cyclists who began to turn it into a cult. Today the brand is one of the few companies that still factory bike this vehicle in the UK.
One of the great benefits of Brompton Bicycle brand, coupled with their sizes and volumes are not very large, is that they are foldable, this means that the bike can be transported easily by folding parts of your design. Being in semifolded position can be easily mobilized in this position with a cart with wheels bicycle brings in the pack when you buy, if available bicycle rear case, this alternative is the simplest.
The Brompton bicycle contains a standard plastic wheels if you, in case you need to change it to flow better quality, you ought to change. The quality of these compact folding bicycles, lets you save them under the computer desk in a stairwell or in a closet. For example, if you go to the gym daily and it has lockers for storing personal belongings, probably Brompton Bicycle brand fits in it.
Circulate on a bicycle Brompom Barcelona is entertaining and offers advantages: it makes perfect, offers great stability and the gearbox adapts to most urban trips in this city.
The bikes feature fender Bromptom preventing you wet when you ride on a puddle of water or wet conditions. All parts and components of the Brompton bikes are of high quality. No matter how long you have used, following good maintenance frequently, it´s rare that these bikes have some breakage, slack or loose parts. They are very strong and durable models.
The Bromptom stores put at your disposal a line of accessories that have been specifically targeted for their bikes. It contains porters, electricity and various travel bags to carry on the front, which can be used also as backpacks or briefcases independent.
This brand of bike has definitely settled in our domestic market as one of the most bikes sold throughout the year, especially in the city of Barcelona, where the use of this transport is quite usual.
