A stationary bike is a bike that is fixed in place, while a spin bike has the pedals on a movable axis. The stationary bike is often used for rehabilitation purposes and the spin bike for aerobic exercise. A stationary bike is often used for rehabilitation purposes and the spin bike for aerobic exercise. The stationary bike and the spin bike have a few things in common. There is a seat on which the rider sits, pedals, gears and chain and handlebars for steering control. There are also differences in the bikes. The spin bike has pedals that move on an axis. The stationary bike has the pedals fixed on a pivot point that allows for pedaling but does not allow for the pedal to move side-to-side. The spin bike also uses a weighted flywheel for smooth pedaling action, while the stationary bike uses air resistance to create its resistance. The stationary bike is used mainly by those recovering from injuries or surgery who need to rehabilitate their bodies while they recover. The stationary bike may also be used by people who are obese and need to lose weight or body sculpting.
The spin bike is used for aerobic exercise. Spin classes are offered in many gyms, where riders can participate in a class setting. These classes have the same types of movements as a spin bike class, often using music to motivate riders to move through the routine. These classes are generally 45 minutes and use a specialized playlist. The workout is designed to be similar to a spin class, with the emphasis on proper form, but exercise can also be performed at home. An indoor stationary bike may not be efficient for burning fat. However, if an individual does not have access to an outdoor stationary bike or the weather is too hot or too cold, an indoor stationary bike is the best option for them. It is important that riders use the proper technique when pedaling either type of bicycle. Please see: Proper Technique The spinning bike is a good alternative to other forms of exercise such as cycling or jogging. An indoor spin bike can be used in the winter when it is too cold to run or ride a bike outside. It can also be used in the summer to stay indoors and avoid the heat. The spinning bike is also good for people with injuries who may not be able to run or cycle outdoors. Indoor stationary bikes are useful for losing weight and burning calories. While they can't provide true cardio exercise like stationary bikes, they do help burn calories and fat while at rest, helping an individual lose weight indirectly while working on other fitness goals such as strength training.
spin bike
A spin bike is a form of exercise bike that is used in spinning classes. Spin bikes are typically made of steel and have a padded seat with adjustable handlebars, pedals, and seat height. It is normally used for both indoor and outdoor classes, albeit outdoors in parks or on the beach. The pedals go round and round either on the ground, mounted to a chain drive or through a belt drive. The gear range is typically 8–10 in/rev with speeds of up to 18 miles per hour. Spin bikes are often used also as stationary bikes due to their low cost and durability. Recently, they have been gaining popularity as an alternative workout option due to its convenience, low cost and more efficient use of space compared with elliptical machines or treadmills which require floor space for use. Spin bikes allow a user to have a high-intensity workout with their own body weight and minimal equipment. It is an excellent cardio workout that can burn hundreds of calories in one class session. Many spin bikes are used in indoor cycle classes, where they are adjusted for each member based on height and comfort level. Spinning classes can be done in either indoor cycling studios or just about any gym with a spin bike available for the class participants. Spin bikes were originally designed by Jon Benson, founder of Mad Dogg Cyclery, when he was trying to create a machine that simulated both running and biking yet gave the user total control over his/her workout (with no upper body work). 
Benson, being a bike racer himself, wanted to design a machine that would help bike racers get in shape for racing season. The first prototypes used an under-seat pad with rollers (similar to rollers used to transport mail) and the pedals were attached directly to the rollers. The pedals themselves were attached to chains underneath the seat, driving another set of rollers. In this way, each pedal was offset from its neighbor by about 7 inches. As the pedal was pushed forward on one side of the machine, it rolled over a small roller which would then send it spinning backwards on the other side of the machine. This allowed ease of pedaling while adding resistance as well. The bike was designed to be used with the seat and handlebars in an upright position, as if a bike racer was competing. The first prototypes were built at a race team shop owned by Jon Benson and Patrick Seagrave. The bikes became so popular that they were moved into the front of the store and used for training by everyone from road racers to mountain bikers. The bikes at first started out as training machines, but they soon became so popular that people started using them instead of running on treadmills. They quickly grew in popularity with the professional cycling world, where they were used by such famous riders as Lance Armstrong and Greg LeMond.
stationary bike
A stationary bike is a type of exercise bike that is designed to be used while standing in place. These bikes are also known as upright bikes, spin bikes, or exercycles. A stationary bike may be used for exercise, but it is also common for people to use them as a cardiovascular exercise machine. They are commonly found in gyms and fitness clubs, in public parks or on personal property, during the warm months. For example, they are often seen parked by the side of the road or on a sidewalk. In recent years they have become popular with people who work at desk jobs that require standing a large portion of their day (such as receptionists) to help relieve leg pain and increase their lung capacity due to increased blood flow deep in their chest cavities. They can also be used to maintain the user's fitness during the off season for other sports.Stationary bikes are available in basic, mid-range and high-end models. The entry level models are typically offered with only hand pulse sensors and no electronic console or data display at all.
The mid range models offer either a magnetic resistance system or a fluid resistance system (such as a flywheel) in addition to hand pulse sensors and sometimes an electronic console with RPM, odometer, speed, distance traveled, watts generated and heart rate data display. The high end models offer an electronic console or display, data storage and reports and much greater customization. There are four basic types of stationary exercise bikes: upright bikes, recumbent bikes, indoor cycles and outdoor cycles. Upright bikes are typically made of metal, have a weighted flywheel, hand pulse sensors and are adjustable for height. Recumbent bikes are also made of metal, but have only a non-weighted flywheel. Indoor cycles such as the ErgCycle or Spinner use a fluid resistance system that is not found on upright stationary bikes or recumbents. Outdoor cycling consists of riding bicycles on the road or mountain trails but is also an option for stationary exercise bike training and workouts through the use of video games that record performance and can upload data to online fitness tracking websites. Stationary bikes are available in upright, recumbent and indoor cycles. Indoor cycles such as the Spinner or ErgCycle use a fluid resistance system not found on upright stationary bikes or recumbents.
Indoor cycles are typically smaller than upright stationary bikes and recumbent stationary bikes, are a little more expensive, but have the distinct advantage of being quiet and not producing much excess heat (which can be uncomfortable for some people). Although a stationary bike is an excellent cardiovascular exercise machine it does have its drawbacks. The seat is designed to be firmly placed against the user's body so that motion is limited as to prevent excessive shaking of the bike during use. This means that many stationary bikes are not appropriate for use while sitting at the desk. Furthermore, some users experience discomfort while using stationary bikes because of overly tight handles or the lack of handlebars. Some people prefer to use a stationary bike in an upright (or slightly reclined) position, but this can also lead to back pain and knee strain. Another difficulty is that of non-weight bearing exercise as opposed to weight bearing exercise such as weight training or running. This means that a person will not get the same cardiovascular conditioning benefits from using a stationary bike as they would from running on a treadmill at the same speed for similar lengths of time (although this depends on individual fitness levels).
