How do I buy a bicycle?

Most Fixed-gear bicycles or fixed wheel bicycles are a subset of single speed bicycles, however it is possible to have a multi geared fixed gear bicycle. Fixed gear bicycles do not allow the rider to coast without pedaling while a single speed freewheel bicycle does. Fixed gear bicycles simply lack any sort of ratchet mechanism that allows the pedals to coast independently of the drive wheel. Both types of these bicycles are, in general, truly single speeds; however, fixed gear bicycles require distinct skills of their riders.
