Solid tires

Some years ago, a new generation of tires for bicycles appeared in the market. Its main innovation consisted in being solid. This issue is widespread in other markets such as motorbikes or scooters. As far as I know, Tannus and few other companies sell them. The first firm sells solid, patented tires. Although they still present a low introduction in the bike market, those who have tested them offer interesting points in favor and against them.

On the one hand, the most positive issue is say goodbye to punctures and flat tires. Since it has no air, they can not get a puncture. Additionally, solid tires last for more time and kilometers in comparison with traditional tires. Versatility is also a good point at least in the Tannus catalog since other companies offer a reduced stock. Not only proposes this firm several tire colors, but also different sizes and surface patterns. Moreover, the impact of weather on them is reduced as a result of the specific chemical compounds (Either in the case of the Tannus tires) these tires are made of. What is more, at least in this case the material is environmentally safe.

On the other hand, such tires present disadvantages. They are more expensive and slightly outweigh the traditional tires. However, Tannus affirms that if you take into account the tools to repair a puncture, then their tires weight less than the air ones. Furthermore, and at least with the Tannus tires, the mounting process is peculiar. I am not saying that it is difficult or impossible, rather it is challenging and laborious, and you need to be strong enough specially in the mounting step. And the fact of no allowing adjusting air pressure based on terrain could be a problem if you ride on different surfaces.

A third option appeared in the marked consisting in the hybrid solution. I mean considering an air and solid tire. It has two zones. The inner one is similar to the traditional tire and full of air, whereas the outer area is exclusively solid. This way bikers gain extra resistance against punctures and they can adjust air pressure.

3rd June

UN declared 3rd June as the World Bicycle Day in April 2018. As they said, International days are occasions to educate the general public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. International days are proposed by member states to the UN General Assembly. This Assembly determines by consensus whether to adopt the resolution establishing the particular day, 3rd June in this case.

Leszek Sibilski leaded a campaign to promote a resolution of the UN for the International Bicycle Day. It went ahead thanks to the support of 57 countries. Finally, it was adopted by a consensus of 193 member states. The International Bicycle Day logo was designed by Isaac Feld and professor John F. Swanson defined the one’s animation.

Why do we celebrate it? The bicycle is simple, affordable, reliable, clean, environmentally sustainable of transportation, and improves your health. UN acknowledged bike as the uniqueness, longevity and versatility which has been in use for two centuries. Indeed, they encourages member states to:

  • pay special attention to the bike cross-cutting development strategies and to include the bicycle in international, regional, national and subnational development policies and programmes

  • improve road safety and integrate it into sustainable mobility and transport infrastructure planning and design, in particular through policies and measures to actively protect and promote pedestrian safety and cycling mobility, with a view to broader health outcomes, particularly the prevention of injuries and non-communicable diseases

  • emphasize and advance the use of the bicycle as a means of fostering sustainable development, strengthening education, including physical education, for children and young people, promoting health, preventing disease, promoting tolerance, mutual understanding and respect and facilitating social inclusion and a culture of peace

  • adopt best practices and means to promote the bicycle among all members of society, and in this regard welcomes initiatives to organize bicycle rides at the national and local levels as a means of strengthening physical and mental health and well-being and developing a culture of cycling in society

Cycling is time-effective

Cycling saves time is one of the advantages of using your bike to go to work, study or buy. Pieces of news and research television documentaries have demonstrated it. If you have not noticed it, think about it or just do the following to check it:

– Determine your start and end points

– Make the comparison between these three alternatives:

  • Get in the car, sit in traffic, queue to get into the car park, pay to park, park your car, and arrive to the end point
  • Walk to the bus stop, wait for it, get on bus (pay), watch the roads throughout the window, leave the bus, walk to the end point
  • Get on your bike, filter past traffic, lock your bike, walk to the end point

I promise you if you do the three experiences, you will discover that using your bike is the fastest ,specially in cities, as well as cheaper. Moreover, you will fight against climate change and practice sport. Furthermore, cycling contributes to reduce obesity and protects your body and your mind.

Cycling body health benefits (3/3)

Continuing with the series about health impacts and cycling, this time I am going to show additional body benefits different from the ones exposed here and here.

When comparing cycling with some other sports, is considered low impact. A lot of research has been carried out in the last years comparing perhaps the two most practiced sports: cycling vs running. The fact of running being weight bearing makes injury rates to be higher in comparison to cycling (which is not weight bearing). This point was demonstrated even with long distance runners and cyclists. When researchers compared both groups, they discovered runners suffered 133-144 per cent more muscle damage, 256 per cent more inflammation, and 87 per cent higher DOMS (delayed onset muscle soreness) compared to the cyclists group. Overall, riding a bike is specially indicated for those who have osteoarthritis since it is a low-impact exercise that places little stress on joints.

Moreover, cycling allows reaching further places compared to other sports in the same time. As a result, it improves your navigation skills no matter where you practice it. You need to remember a route or determine where is the North when riding. Orientation and addresses should be in your memory or you would need to earn your daily bread with your own resources, no matter whether you are cycling in a city, mountain or countryside.

Furthermore, cycling improves your sexual life. Yes, you have read it right. Why is so? Doctors said the muscles developed on the bike are used during intercourse. The better developed these muscles, the longer and more athletic intercourse will be. And it works for women and men.

Next, it is not rocket science that tiring yourself out on a bike will improve your sleep. Researchers determined sleep problems to those people who drop between 2-4 per cent in cardiorespiratory exercise practice, no matter the people gender. Looking for the causes, they suggested it could be a reduction in anxiety brought by exercise than improves the ability to sleep. Bike exercise also protects against weight gain with age, which is another cause of sleep dysfunction.

Finally, riding a bike also increases handling and spacial awareness. Climbing, descending and cornering, among others technical elements, teach you how to use your body weight to get the bike to go where you want it to. Gaining the skills to manage these technical elements can provide an increase in your muscles and a massive confidence boost, specially when you start to see improvements. Posture and coordination are also improved. And it only takes two to four hours a week to achieve a general improvement to your health.

How to carry the shopping

The sum bicycle plus shopping is seen as something difficult or even incompatible by non-bikers sometimes. But when it comes to use your brain to solve this apparently important problem, it all has sense.

First of all, freedom is increased in comparison to using a car. You can park your bike easily and it occupies less space. Secondly, you exercise your body.

Moreover, you need a rear rack, saddlebags or just a backpack. Regarding saddlebags, the best way to organize them is putting the heavier and less fragile objects at the bottom, i.e. tins and boxes. Next, put the most breakable items on top such as eggs and bread. Remember to distribute weights uniformly in your saddlebags in order to avoid your bike bending.

Thirdly, you can use a bicycle trailer or a cargo bike to carry extra shopping weight in addition to people. Finally, never ever forget locking your bicycle by at least two points while going shops.

covid-19

Back in 2020, humanity faced a disaster officially known as covid-19. Hundred of thousands got ill and thousands died. The negative impacts of such a pandemic are well-know, but on the other hand, there were few positive points.

Regarding the essence of this blog, the most important one was the compulsory, drastic reduction in the use of vehicles powered by a combustion engine in most countries. This was so in order to diminish contacts between people and avoid infections. At the same time, this action leaded to an unprecedented pollution reduction. It was so impressive that only climate scientists and other specialized workers in the field had previously noticed the remarkable improvement in quality air. News and scientific analyses confirmed their believes. For example, data in Valencia, Spain, showed a more than 50% drop in nitrogen dioxide, as well as an extraordinary fall in CO2 production. Similar results were measured in central European countries, Italy or China. Noise was also reduced and contributed to improve quality lives. Thus, the moral of these adopted measures to war against the virus was the less vehicles powered by a combustion engine running, the better for human health and environment.

This is a lesson for skeptical people and specially those politicians who still hinder fights against climate change. Pollution and noise negatively impact human health and using your bike is an excellent method to become part of the solution, not part of the problem.

Cycling body health benefits (2/3)

Continuing with this series of posts, in the first one I talked about health benefits of cycling: weight control, muscle development and immune system reinforcement. Now, I am going to highlight the benefits of riding regarding diseases.

Researchers have demonstrated blood pumping your body and calories burned when riding helps you cut your risk of developing major illnesses such as heart disease and several kinds of cancer. For instance, cycling to work was showed an impact of cutting half the risk of suffering heart attacks or cancer in 260,000 individuals over the course of five years.

Second, cardiovascular disease is a term than includes stroke, high blood pressure and heart attack. By practicing regular cycling, one stimulates and improves her heart, lungs and circulation. Conversely, she reduces her risk of cardiovascular disease. This is related to the fact that riding strengthens your heart muscles, lowers resting pulse and reduces blood fat levels. The comparisons are odious, but research demonstrated that people who cycle to work have two to three times less exposure to pollution than car drivers, and their lung function is improved.

Third, type 2 diabetes is related to lack of psychical activity as a clear indicator of developing such a disease. Large-scales researches have shown than riding for more than 30 minutes per day had a 40 per cent lower risk of developing this type of diabetes.

Related to a previous point, bicyclers are exposed to fewer pollution than car drivers. Indeed, researchers measured air pollution through detectors fitted to a driver, a bus user, a pedestrian and a cyclist. These people moved through a busy route in central London. The results showed the car driver experienced five times higher pollution levels than the cyclist and three and a half more pollution measures than the bus user. As a result, lung health improves when riding instead of driving a car.

Cycling body health benefits (1/3)

Cycling is related to psychology and produces a series of mental benefits as I wrote about it here, here and here. On the other hand, it also provokes a lot of body health benefits. The first post of this series deals with the weight control, muscle development and immune system reinforcement.

The basic equation when intending to loss weight is calories out must exceed calories in. In other words, you need to burn more calories than you consume. Researchers have determined that cycling burns between 400 and 1,000 calories per hour, depending on intensity and bicycler weight. Other research shows that riding for just thirty minutes every day will burn nearly five kilograms of fat over a year. Furthermore, you decide the time and intensity of cycling, thus you can adapt them to your needs.

Additional implications are the joy this activity produces when practiced and how much time you spend burning calories on a bike. Moreover, riding increases your metabolic rate which is closely related to burning body fat. However, weight loss by cycling is boosted with a healthy eating plan.

Next, riding a bike also builds muscle, specially around the glutes, hamstrings, quads and calves. Impressively, muscle is leaner than fat and people with a higher percentage of muscle burn more calories practicing the same sport.

Finally, the immune system is strengthen when cycling. Researchers have found benefits of the upper respiratory system (and reducing instances of the common cold). In addition, mild exercise can improve your immune system by increasing production of essential proteins and waking up lazy white blood cells.

Nevertheless, some research suggests that immediately after intense exercise your immune system is lowered, but adequate recovery such as eating and sleeping well reverses it.

Avoid bicycle thefts

How can I avoid bike thefts? There are several points you can do:

  • Always use good bike locks when locking it. For instance, follow the advices here and here

  • Lock your bike to solid, robust objects.

  • Lock your bike in place of passages. This way someone can see a theft and call the police or at least threaten him to do it.

  • If you can, select strategist places to lock your bicycle near such as police stations.

  • Do not let your bike rest at night under the stars, better allow it to do it indoor.

  • Perhaps use a psychological trick like this one

  • Never buy a bicycle without receipt. If you do not follow this advice, you are probably supporting bike thieves and the black market.

  • If you can, do not legally buy a colorful bike since this fact attract people eyes including the thieves ones.

  • Decorate your bike with an anti theft sticker. Not sure if this would stop a theft, but at least it can make you laugh:

Bike and psychology (3/3)

I can not conclude this post series (which started here) without writing about an undesirable piece in the bicycle world. I am talking about the bike thieves. Millions of bikes are stolen every year by mainly young males in gangs. Then, they sell the bikes both on the street and online.

Why stealing bikes is so prevalent? According to police services, it is attractive because represents a low risk and cost activity. However, most of stolen bikes are sold at low, sometimes ridiculous, prices. Thus, the psychology here lies in the economic thinking of earning some money with low risk.

The reasons of bike thieves are varied and range from envy to experience a shot of adrenaline. But I think the most important facts is poverty and sometimes related to drug addiction. In fact, this is closely linked to the low cost point that I have mentioned in the previous paragraph. And I reckon, it is partially and indirectly motivated by the shameful fines this action is punished in most countries. Even in relapses, thieves just spend few months in jail. If only politicians feel the importance of having a bike for whatever need (going to college, university, etc., going to work or to buy, practicing sport, fight against climate change, feeling better, you name it).

Few psychological studies have being carried out in this field. One of them was conducted at the Newcastle University campus. Here, the researchers analyzed the impact of installing signs with images of “watching eyes” with a written message as it comes to bike theft. They monitored thefts for 12 months after an before the signs installation. Several location were divided as control (no signs were installed) and experimental (signs were installed). While experimental locations thefts were reduced by 62 per cent, they increased in control ones by 65 per cent. This suggested the importance of signs, but also that crime was displaced to the control locations. Nevertheless, the importance of surveillance was shown.

According to the report, humans have fast, automatic psychological mechanisms which have evolved to respond to eye-like stimuli, and that even mere representations of eyes affects us. We are eye-animals.

On he other hand, it would be great if thefts perception changes towards a more punishable, risky and highly economic cost activity. Fines and prison sentences should increase in bikes thefts as well as bicycle parts.
