Bicycling is an excellent way to get exercise and stay physically fit. However, many urban environments in the modern world of today do not have sufficient locations where a person can ride a bicycle in peace without having to worry about bumping into people and cars. Your luck is even worse if the place where you plan to cycle is far from your home, and no easy route (preferably a bicycle-friendly one) to the place exists. That automatically makes it impractical to drive to the place and back with your bicycle day after day, spending time you could have spent doing other things. You can even miss episodes of your favorite TV show because you were busy driving yourself and your bike to your location of choice.
Also, if you are a man of the city, how much use are you going to get out of your bike anyway? Chances are, not much. The metropolis is not keen on letting you cycle freely anywhere you want, and being a resident of it, you have to play by the rules or face the consequences.
Or you can just get a bicycle trainer.
A bicycle trainer is a type of exercise equipment that lets you experience bicycle rides in the comfort of your own home, without having to worry about running someone down or finding a good place. It is basically a frame, equipped with clamps, to which you have to affix your bicycle. Once locked in, a cylindrical roller will be pressed against the rear wheel of your bike. The role of this roller is quite unique, as it is used to generate a semblance of resistance when the mounted bike is being ridden. The level of this resistance can be adjusted, helping to simulate smooth roads as well as steep mountain paths.
Bicycle trainers can come in many shapes and sizes. Take the wind trainer, for instance. Using a massive fan blade mechanism (driven by the roller of the trainer), it generates variable amounts of air resistance for the rider. These trainers are noisy, but highly economical due to its low price. A somewhat less noisy type of trainer, magnetic trainers use opposing polarities of magnets to generate resistance. The resistance level can usually be controlled through a control panel. Fluid trainers, the most silent type of trailers, make use of fluid-filler chambers to create resistance. Some trainers also create resistance using a centrifugal pressure system.
The bicycle trainer is a great alternative for individuals who love riding bicycles, but cannot do it regularly due to environmental reasons. One might argue that an exercycle can be used to achieve the same effect, but that is actually not the case. You cannot attach your bicycle to your exercycle, which means the feelings associated with the ride can be drastically different during exercise due to the different nature of the machine.
Many modern bicycle trainers come with electronic sensor systems designed to observe the performance of the rider, such as heart rate, apparent speed, power output etc.. Data from these sensors can be used to enhance the exercise experience even further, and many expert cyclists use the data from them to keep track of their fitness program.
Many hardcore cyclists often use bicycle trainers for their everyday training to save time and money. Rather than being at the mercy of weather and traffic, they can now cycle in their own rooms while enjoying music or watching television. Indeed, not having to keep your eye on the road leaves it free for other uses, so why not put it to use as well?
