Puncture: Wheels

There is a fact when riding a bike that is considered a handicap for some people and an opportunity for some others as these last put into practice what they have learned. Traditionally, this issue has been usually presented when riding on a surface clogged with tacks and crystals. Of course, I am referring to punctures.

Punctures constitute a headache for some cyclists. Putting aside how to repair them, which I will talk about in the future, this post is dedicated to wheels that are able to avoid them. You can find two solutions for them in the market: Flat tyre, and gel wheels.

On the one hand, the flat tyre makes impossible to puncture a wheel. The absence of air inside it allows you to ride on tacks without any problem. Moreover, most flat tyres are made with long-lasting materials as they work for thousand of kilometers. On the other hand, the gel wheels incorporate a gel material inside them. This material vulcanizes in contact with air, hence the puncture is automatically repaired. In fact, biker does not usually realize he or she has a puncture after finishing the ride. However, this wheel should be changed after a high number of punctures since the gel quantity reduces after every puncture.

Furiosos ciclistas

Furiosos ciclistas (https://www.furiosos.cl, in Spanish) is a Chilean bike group that aims at promoting the bicycle use in the urban scenario. Bikeactivists compose it and fight for their legal and cultural recognition, increment in security when riding, teaching other stakeholders in the streets, improving human health, creation of bike infrastructures and crashes reduction.

They propose specific points to reach these targets: Planning, design and engineering, promotion and education. Why have they chosen bicycle as the ideal issue to manage them? Bikes are efficient, economic, environmentally friendly, accessible, allow progress towards human contact, and human health. Back in 1995, this group began as a yield to the dominant abuse of motor-based ways of transport, what they call Imperio Motorizado Sin Freno (Non-brake, motorized empire, in English). Notice the Chilean humor.

You can read posts and watch short videos about different aspects related with urban cyclist on its website. Subjects range from activities and highway education, to the Critical Mass and bike-tourism, including both national and international news as it comes to bikes.

Mujeres bici-bles

Andrea María Navarrete is the founder of Mujeres Bici-bles, a bike women group with the aim to empower themselves. Mujeres Bici-bles is a Latin American social movement with headquarters in Colombia, Mexico, Peru, Bolivia and Argentina. Their main target is to help women to ride bikes in urban scenarios. Urban biking can be difficult for men, but it is more problematic for women specially in the patriarchal societies. Thanks to the mind of its founder, who is also a university teacher, urban cyclist and touring cyclist, this movement has quickly spread. They support other women who want to start riding a bike. For instance, in the Colombian cities of Bucaramanga and Salta, they have informal schools to teach more women pedaling.

OK, but what if I want to create a Mujeres Bici-bles group in my city? Well you can contact to Andrea María through [email protected] or Twitter (@MujeresBicicles).

She offers a talk, the group creation and, if future bikers want, interesting teachings about how to create the bike school for women in every city she travels. In return, Andrea María asks for help to move to another city and a place to spend a few days. Once the group is created, she proposes talks regarding genre perspective, and pedaling and mechanics workshops.

Bike monuments

Monuments have been using to honor or commemorate somebody or something for ages. Kings, conquerors or discoverers overcrowd them as it comes to persons. Regarding buildings, there is a myriad of them with different architectures across the world. Thus, we are used to seeing them in most cities.

What is more surprising is to come across with a bike monument. This is a structure in which a bicycle appears alone or as part of a sculptural ensemble. As the bike movement develops, more and more bike monuments are built to express the change that society is experiencing. Similarly to queens and kings sculptures, bike monuments constitute what people gives importance.

Perhaps there are more bikers collecting bike monuments, but I only know one person who is truly doing this. In the Bicimonumentos (in Spanish)  webpage one can consult bike monuments in a lot of countries. It is impressive realizing that the love for bikes is so widespread. By the way, if you want to send it some bike monuments photos or locations, you can do it by sending a private message to https://www.facebook.com/LaMujerDelTiemp. Also, the blog http://www.salamancaenbici.es/ could receive bike monuments information but I am not completely sure about this last point.

Less waste grounds

In some pro-car cities, waste grounds are usually occupied by cars. These empty lands appeared as a result of the house bubble crash or because of numbness politicians. The fact is that these areas can be better places for instance by transforming them into public gardens. This way the neighbors’ life quality increases, children can play without risk of being run over, senior citizens can drift around and everybody can play sports. Thus, everybody benefits.

When brave mayors decide to convert waste grounds into gardens, some car drivers normally claim against it due to the fact of losing free parking lots. The most idiot ones argue that as they lose them, they should pay less car taxes. What they do not see, or do not want to understand, is the problems cars cause because of driving or having them. A car is like a weapon. It has been used in the past by terrorist to cause victims, the poison expels by exhaust pipes kills every year hundreds of thousands of people around the globe, thousands more are killed in car crashes and millions probably die because of global warming. Indeed, driving polluting vehicles is the source of 20% of all US emissions (http://www.ucsusa.org/clean-vehicles/car-emissions-and-global-warming#.Wa7nNdRLdAg) or 17% of the UK’s total carbon dioxide emissions (https://www.theccc.org.uk/publication/impact-of-real-world-driving-emissions/).

So, the more green areas, the better quality of life for citizens.

A different bike line

Riding a bike uses to be a happy activity. If you do it in a park or a forest, then it turns into a relaxed, quiet trip. The relation of bicycles with environment has been deeply studied regarding the avoidance of pollution and the replacement of motor vehicles. As you know, bike lines constitute the specific paths for bikes. It would be ideal if these points could be joint in a unique infrastructure.

It turn out that this building already exist. Genk is a city in Belgium which has made it possible. They were to build a bike line in a park, but faced a problem: How to cross a lake. Engineers thought over it with the intention of integrating it into nature. So, traditional bridges were discarded. Finally, they came up with the following:

Every cyclist I know want to ride it. It is awesome, marvelous, cool, you name it. And above all, it represents the complete integration of bikes with environment. The optic effect makes as if those bikers were riding on the water, although it presents a little trick:

When raining, the special pavement and the lateral guides evacuate the water.

Donostia

Donostia is one city in the north of Spain. It has gone after making citizens lives healthier for ages. Back in the 90s, the city started changing its goal towards people and sustainable mobility. As a result, pedestrianization was shyly used with the opposition of some businesspersons and political opponents at the beginning. The first group feared a reduction in sales, whereas the former made noise just to try scratching some votes. Fortunately, sales in local businesses increased in pedestrian areas since potential buyers had more time to walk absentmindedly, hence to enjoy the short-noise, pleasant spaces. These interventions have improved people life quality and showed other cities the right path. Such actions were spread out strategically to historical and tourist areas like the Concha beach as time went by. In turn, satisfaction indicators boomed. Today, local businesspersons demand strengthen pedestrianization to the mayor conversely to what asked for at the end of the last century.

Regarding bicycles, Donostia has made efforts to build bike lines, increase the bike road network to more than 52 km, implement Dbizi (the local public bike sharing system), create the Bicycle Observatory, a bike registry, etc. The Bicycle Observatory (http://www.cristinaenea.eus, in Spanish and Basque) aims at promoting the bicycle use in the city by giving practical tips, rules and explaining the relation between bicycles-pedestrians / bicycles-cars to urban bikers and stakeholders. Moreover, it gives advice about what to do when your bike is stolen. And finally, it organizes courses and workshops to foster the bike use.

Pontevedra

Pontevedra is a city in the northwest of Spain. It has been internationally recognized for its efforts in promoting healthy life among its citizens. Others cities in the world copy its actions at urban planning to improve life quality by the process in which if an intervention works in one place, it is about to be successful in another one. But how has it been acknowledged towards sustainable mobility?

Miguel Anxo Fernández Lores has been its mayor since 1999. At the begging, he put his hands on his head as 14,000 cars passed along some streets while much less neighbors lived on them. He had in mind ending with this nonsense. Today, Pontevedra is one of the quiet cities in the noisy Spain.

In this time, he has transformed the city by following a simple and powerful idea: Owing a car does not give you the right to occupy the public space. This philosophy confronts to what has been the dominant model in cities: Throwing out children and senior citizens from streets because of cars. At the beginning pedestrianized all the medieval center (300,000 squared meters). This allowed natives and tourists enjoying so vast area. They realized people looking for a place to park caused the most congestion, thus stopped cars crossing the city and got rid of street parking. They incorporated other actions like extending the car-free zone from the old city to the 18th- century area, substituted traffic lights by roundabouts and traffic calming areas by reducing the speed limit to 30 km/h.

An interesting and copied idea was the launch of the Metrominuto. The Metrominuto is a map centered in the aesthetics of metros maps, which marks the pedestrian distances between the most important points of the city and the time it takes to travel them:

Metrominuto

Thanks to this beneficial interventions nobody has died in car accident in the city since 2009, whereas 30 people died from 1996 to 2006. CO2 emissions reduced 70%. Almost three-quarters of car journeys are made on foot or by bike. Withholding planning permission for big shopping centers protected small business. The works were exclusively financed locally and received no aid from regional or central government.

To sump up, motivated leaders with the unique target of benefit society and a sustainable mobility vision is what cities need.

Intermodality (2/2)

As I talked about, intermodality is the combination of two or more ways of transport. The first post dealt with bikes and buses, whereas I am going to enhance your knowledge on the subject of the sum bikes plus trains today.

Lots of people use the conjoint ways of transport in an everyday routine to go to work or study. This intermodality is well-developed in those countries which enjoy a vast railroad which in turn constitutes a serious competitor against cars. Moreover, the train lines which go to parks fill up on weekends. One can see two main modalities in this intermodality. The first one appears when bikes can get into the train with no specific area where to put them. It is like if you go inside the coach and lock your bike wherever you can. This fact could make the trip uncomfortable to some passengers, but the point here is the authorities tactlessness as they have not considered the bikers necessities.

In comparison, the ideal alternative is to dedicate specific carriages for bikes. Usually the first or the last coach is highlighted with bicycle pictures on the bodywork or the windows, so that everybody understand it as the place to put the bikes. In the next photo, you can see how it works. Notice the division in bikes-area and people-area. This way makes it easier for riders to seat close to their bikes.

Nevertheless, there is another way to transport bikes. In the previous picture, bikes were put in horizontal as they move on the road. The next option is to hang them to gain extra capacity (see the next photo). Again, a zone for bikers is needed, limited by the two transparent panels. The central corridor also allows the engine driver to move freely.

In addition, if the train station has a good and large parking bike like in the next picture, the use of train by riders is increased.

Intermodality (1/2)

Intermodality means to share two or more ways of transport to go from point A to point B. Usually intermodality deals with shared transports like train, bus or metro. As it comes to bicycles, the more advanced countries facilitate intermodality by linking bikes and buses, or bikes and trains. The sum bikes and metro is complicated in peak hours such as the ones in which most people go to work or study. The limited space makes it difficult to share the limited surface specially in those more important metro-consuming countries like Japan.

Regarding the sum of bikes and buses, different alternatives are faced with in my opinion no clear winner. On the one hand, there are cities which allow getting in bikes into buses, but only those that are folding. The reason, again, is the lack of sufficient space due to seats and also passengers. This idea can get it off the hook in intensive-use foldable bikes places, although most of them (and probably all of them) do not accomplish this characteristic.

On the other hand, there are the systems which enable to incorporate bikes to the buses chassis. Here, ingenuity is put into play and an external structure is added to mount the bikes. It can be done at the front or behind of buses. On the photo bellow, you can see it at the front in real life.

The number of bikes is limited by their weight and the mechanical tolerance of the incorporated structure. A simple transporter carries one to four bikes which are mounted in a few seconds. As the bus driver continuously sees them, he controls them and the bus times are not substantially affected.

Moreover, when bicycles are put behind the bus, we have two options. The first one constitutes using a more complex alternative compared to what I have showed and can be observed in the next picture.

This assembly can carry more bikes, but it requires extra height and strength that not every people have. Hence, help is needed. The positive point that implies it is the capacity is increased, though the photo only shows four positions. However, the bus driver can not control the bikes unless she get off it or the rider warn her.

And finally there is the preferred option in long bus trips and dozens of bikes: To hitch a trailer. A trailer allows for moving lots of bikes while the space for bikers inside the bus is guaranteed. If using a two-story trailer like in the next photo, bikes must be secured by hooks in order not to go flying in the first corner. Additional actions are recommended to avoid thieves like using chains.
