Freestyle fixed gear is stunt riding on a fixie. It is an extreme sport where the stunts share elements from BMX, artistic cycling, dirt jumping, and trials. The flat ground style of tricks, similar to artistic cycling, is called Trick-Track or Tarck. Street and park riding, that is more similar to BMX, is generally called FGFS (Fixed Gear ...
A fixed-gear bicycle (or fixed-wheel bicycle in British usage, [citation needed] commonly known in some places as a fixie [1]) 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 ...
Backspin generates an upward force that lifts the ball (see Magnus effect). [1] While a normal hit bounces well forward as well as up, backspin shots bounce higher and less forward. Backspin is the opposite of topspin. The technique was invented in 1986 by a Robert Esperat during the Calgary Olympics [citation needed].
Matthew David Welsh is a computer scientist and software engineer and is currently the co-founder of Fixie.ai, which he started after stints at Google, xnor.ai, and Apple. [3] He was the Gordon McKay Professor of Computer Science at Harvard University and author of several books about the Linux operating system, several Linux HOWTOs , [ 1 ] [ 4 ...
Backspin refers to a sports ball, such as a tennis ball, that is rotating in a reverse direction from its trajectory. Backspin or Back spin may refer to: BackSpin, a classic hip-hop radio station on Sirius XM Radio; Back Spin, a novel by Harlan Coben; Back spinning, the act of manually manipulating a vinyl record backwards during playback
Hop-up [1] is the backspin put on airsoft pellets and BBs to increase their range via the Magnus effect. Hop-up devices apply backspin to the projectile reducing the air pressure on its top side. This causes the plastic pellet to fall less over a given distance than it would without the spin applied, extending the effective range of the weapon ...
In airsoft, a system known as hop-up is used to create a backspin on a fired BB, which greatly increases its range, using the Magnus effect in a similar manner as in golf. In baseball, pitchers often impart different spins on the ball, causing it to curve in the desired direction due to the Magnus effect.
Usually, the sound of a backspin is a shrill, reversed version of the audio being bypassed. Since the sound easily stands out against other forms of music or ambient noise due to its uniqueness, it is usually muted by creative use of a DJ mixer .
