A trainer consists of a frame, a clamp to hold the bicycle securely, a roller that presses up against the rear wheel, and a mechanism that provides resistance when the pedals are turned. In a wind trainer, the roller drives fan blades that create air resistance. These are typically the least expensive and noisiest trainers. Magnetic trainers have magnets and a conducting flywheel operating as an eddy current brake. They are moderately expensive and moderately noisy. Some magnetic trainers have handlebar-mounted control boxes to change the level of resistance during a training session. Fluid trainers use liquid-filled chambers to create resistance. They are the most expensive and quietest trainers. A small number of trainers use a centrifugal pressure mechanism to create resistance, involving pressure plates, ball bearings and specially shaped grooves. These are similar to fluid trainers in price and performance.
Trainers make it possible to build bicycle skills and power very efficiently in a highly controlled environment, without the unavoidable interruptions of outdoor riding. For instance, in hill training, instead of being limited to whatever hills are around one's home, one can simulate any size and steepness. Trainers provide better preparation for racing than stationary bicycles. Trainers require better technique than stationary bicycles, and they provide a more realistic-feeling ride. The geometry and resulting body position of a stationary bicycle may be significantly different from a racing bike; of course, if one uses the racing bike itself in an indoor trainer, the body position is nearly identical.
Some trainers are equipped with sensors that monitor the rider's performance. Power output, cadence, virtual speed and heart rate are among the metrics that can be transmitted electronically. Analyzing these figures can help to fine-tune the athlete's training.
Bicycle trainers are categorized by how the unit provides resistance. There are two broad categories: "wheel on" trainers use the bicycle's own rear wheel, whereas "wheel off" or direct-drive trainers replace the rear wheel with the trainer's own machinery. Within those two categories, there are also 'basic' and 'smart' trainers, which differ through their ability to connect with other devices. Direct drive trainers are almost exclusively 'smart' and Wheel On trainers are almost exclusively 'basic' but exceptions do exist. The Wahoo Kickr Snap is an example of a smart wheel-on trainer.
Usually all trainers can be adjusted for most sizes of road and mountain bikes. However, knobby tires can cause vibration and noise, defeating the purpose of noiseless units.
Smart trainers allow users to connect the trainer to a third party device such as computer, smartphone or tablet, via Bluetooth and ANT+. Applications on said devices are then able to control the resistance provided by the trainer. The users performance is measured by a power meter. The app can then lead the user through a workout, or gamify the experience by letting the user ride in virtual worlds where gradients are felt through the pedals. Popular applications include Zwift and TrainerRoad.
Basic trainers feature no electronics, so cannot connect to third party devices and apps. Instead they rely on a manual controller or a progressive resistance curve. [5] Basic trainers were ubiquitous until the mid 2010s, but with the advent of smart trainers and the imnmersive experience they provide, are now reserved for the entry-level pricepoint.
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
An indoor rower, or rowing machine, is a machine used to simulate the action of watercraft rowing for the purpose of exercise or training for rowing. Modern indoor rowers are often known as ergometers because they measure work performed by the rower. Indoor rowing has become established as a sport, drawing a competitive environment from around the world. The term "indoor rower" also refers to a participant in this sport.
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography and application. Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper posts can be installed to allow the rider to quickly adjust the seat height.
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position. Some recumbent riders may choose this type of design for ergonomic reasons: the rider's weight is distributed comfortably over a larger area, supported by back and buttocks. On a traditional upright bicycle, the body weight rests entirely on a small portion of the sitting bones, the feet, and the hands.
A touring bicycle is a bicycle designed or modified to handle bicycle touring. To make the bikes sufficiently robust, comfortable and capable of carrying heavy loads, special features may include a long wheelbase, frame materials that favor flexibility over rigidity, heavy duty wheels, and multiple mounting points.
Indoor cycling, often called spinning, is a form of exercise with classes focusing on endurance, strength, intervals, high intensity and recovery, and involves using a special stationary exercise bicycle with a weighted flywheel in a classroom setting. When people took cycling indoors in the late 19th century, whether for reasons of weather or convenience, technology created faster, more compact and efficient machines over time. The first iterations of the stationary bike ranged from strange contraptions like the Gymnasticon to regular bicycles placed atop rollers.
A utility bicycle,city bicycle, urban bicycle, European city bike (ECB), Dutch bike, classic bike or simply city-bike, is a bicycle designed for frequent very short, very slow rides through very flat urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday short-distance riding in normal clothes in cold-to-mild weather conditions. It is therefore a bicycle designed for very short-range practical transportation, as opposed to those primarily for recreation and competition, such as touring bicycles, racing bicycles, and mountain bicycles. Utility bicycles are the most common form globally, and comprise the vast majority found in the developing world. City bikes may be individually owned or operated as part of a public bike sharing scheme.
A racing bicycle, also known as a road bike is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI).
A stationary bicycle is a device used as exercise equipment for indoor cycling. It includes a saddle, pedals, and some form of handlebars arranged as on a (stationary) bicycle.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism such that the pedals always will spin together with the rear wheel. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the "fixie" has become a popular alternative among mainly urban cyclists, offering the advantage of simplicity compared with the standard multi-geared bicycle.
A bicycle lock is a security device used to deter bicycle theft, either by simply locking one of the wheels or by fastening the bicycle to a fixed object, e.g., a bike rack.
This is a glossary of terms and jargon used in cycling, mountain biking, and cycle sport.
Bicycle rollers are a type of bicycle trainer that make it possible to ride a bicycle indoors without moving forward. However, unlike other types of bicycle trainers, rollers do not attach to the bicycle frame, and the rider must maintain balance on the rollers while training. Bicycle rollers normally consist of three cylinders, drums, or "rollers", on top of which the bicycle rides. A belt connects the middle roller to the front roller, causing the front wheel of the bicycle to spin when the bicycle is pedaled. The spacing of bicycle rollers can usually be adjusted to match the bicycle's wheelbase. Generally, the front roller is adjusted to be slightly ahead of the hub of the front wheel.
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today.
A motorized scooter is a stand-up scooter powered by either a small internal combustion engine or electric hub motor in its front and/or rear wheel. Classified as a form of micro-mobility, they are generally designed with a large center deck on which the rider stands. The first motorized scooter was manufactured by Autoped in 1915.
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically the second largest source, after wind resistance, of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle.
Zwift is a massively multiplayer online cycling and running physical training program that enables users to interact, train, and compete in a virtual world.
Peloton Interactive, Inc. is an American exercise equipment and media company based in New York City. The company's products are stationary bicycles, treadmills, and indoor rowers equipped with Internet-connected touch screens that stream live and on-demand fitness classes through a subscription service. The equipment includes built-in sensors that track metrics such as power output, providing users with real-time feedback on their performance and leaderboard rankings to compete with other users.
Direct-driver trainers require that you remove your rear wheel, install a cassette on the trainer, and then mount your bike on the trainer.
Smart means they can connect (usually via Bluetooth or ANT+) to your electronic device (phone, laptop, tablet and most of the best cycling computers) to offer variable resistance which is controlled by indoor cycling apps such as Zwift.
Standard bike trainers forego this connectivity and are much cheaper. They either offer a progressive resistance curve (the harder you pedal, the more it resists), or a manual controller, which works in a similar way to dragging the brakes. Of course, if you have a power meter or speed sensor, you can pair those with your Zwift-running device, but the interactivity is lost (Zwift can't control the resistance automatically).
