Cycling is globally regarded as a very effective and effective mode of transportation optimal for short to moderate distances.
Bikes give multitudinous benefits by comparison with motor vehicles, including the sustained physical exercise inescapably involved in cycling, that cycling involves a reduced consumption of fossil fuels, less air or noise pollution, much reduced traffic congestion, easier parking, greater maneuverability, and access to both roads and paths. The advantages also include reduced financial cost to the stoner as well as to society at large.
Among the disadvantages of cycling are the essential insecurity of the cycle, the immensely reduced protection in crashes, longer trip time, vulnerability to rainfall conditions, difficulty in transporting passengers, competition with socially salutary forms of mass public conveyance, a patient tendency for cyclists to intrude into pedestrian areas, and the particular levels of skill and fitness needed by cycling.
