Fan-operated resistance bikes are a bit simpler: As you pedal, the fan blades are pushing against the air around the machine. Your cadence is directly related to the amount of effort required to ...
Larger diameter wheels generally have lower rolling resistance but a higher profile leading to higher air resistance. High-racer aficionados also claim that they are more stable, and although it is easier to balance a bicycle with a higher center of mass, [ 4 ] the wide variety of recumbent designs makes such generalizations unreliable.
The design, coupled with low or dropped handlebars, requires the rider to bend forward more, making use of stronger muscles (particularly the gluteus maximus) and reducing air resistance at high speed. Road bikes are designed for speed and efficiency on paved roads.
Due to the lower air resistance and better body stance for pushing, road bicycles are more efficient for smooth road use. Cyclo-cross bicycles, used for racing on off-road circuits, are closer to racing bikes than mountain bikes. They have wider, treaded tires and are less efficient than racing bikes at higher speeds on sealed roads.
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.
The low-pressure wake behind a group's leading car reduces the aerodynamic resistance on the front of the trailing car, allowing the second car to pull closer. As the second car nears the first, it pushes high-pressure air forward so less fast-moving air hits the lead car's spoiler. The result is less drag for both cars, allowing faster speeds. [3]
