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.
A cogset works with a rear derailleur to provide multiple gear ratios to the rider. Cassettes come in two varieties, freewheels or cassettes, of which cassettes are a newer development. Although cassettes and freewheels perform the same function and look almost the same when installed, they have important mechanical differences and are not ...
A track bicycle or track bike is a form of fixed-gear bicycle optimized for racing at a velodrome or at an outdoor track. Some road racing and club cyclists use a fixed-gear bicycle for training during the winter months, generally using a relatively low gear ratio, believed to help develop a good pedalling style. [5]
The larger diameter thread on the fixed side accepts a standard threaded cog and uses the same size threads as the freewheel side of the hub. The most common standard I.S.O. thread size is 1.375" x 24 tpi (threads per inch), but there are other less common older sizes ( British 1.371" x 24 TPI, French 34.7 x 1 mm, Italian 35 mm x 24 TPI).
One standard option for the Brompton folding bicycle is to use a 3-speed hub gear (roughly a 30% difference between gear ratios) in combination with a 2-speed derailleur gear (roughly a 15% difference) to give 6 distinct gear ratios; this is an example of half-step gearing. Some Brompton suppliers offer a 2-speed chainring 'Mountain Drive' as ...

A magnetic gear is composed of magnets of the type permanent, electromagnetic or otherwise magnetically induced fields. It consists of two or more elements that are usually rotating but can be linear or curve linear in nature. The classical gear is defined as a ratio of pole pairs. Where the Pole pairs are magnets N-S and S-N in nature.
