Some components, which are often optional accessories on sports bicycles, are standard features on utility bicycles to enhance their usefulness, comfort, safety and visibility. [[Fender (vehicle)|Fenders]] with spoilers (mudflaps) protect the cyclist and moving parts from spray when riding through wet areas. In some countries (e.g. Germany, UK), fenders are called mudguards. The [[chainguard]]s protect clothes from oil on the chain while preventing clothing from being caught between the chain and [[crankset]] teeth. [[Kick stand]]s keep bicycles upright when parked, and [[bike lock]]s deter theft. Front-mounted [[bicycle basket|baskets]], front or rear [[luggage carrier]]s or racks, and [[pannier]]s mounted above either or both wheels can be used to carry equipment or cargo. Pegs can be fastened to one, or both of the wheel hubs to either help the rider perform certain tricks, or allow a place for extra riders to stand, or rest.{{citation needed|date=May 2013}} Parents sometimes add rear-mounted [[Baby transport|child seats]], an auxiliary saddle fitted to the crossbar, or both to transport children. Bicycles can also be fitted with a hitch to tow a [[bicycle trailer|trailer]] for carrying cargo, a child, or both.

[[Clipless#Clipless pedals|Toe-clips]] and toestraps and [[clipless pedals]] help keep the foot locked in the proper pedal position and enable cyclists to pull and push the pedals. Technical accessories include [[cyclocomputer]]s for measuring speed, distance, heart rate, GPS data etc. Other accessories include [[bicycle lighting|lights]], reflectors, mirrors, racks, trailers, bags, water bottles and [[Bottle cage|cages]], and [[Bicycle bell|bell]].<ref name="bicycleuniverse">{{cite web|url=http://bicycleuniverse.info/eqp/accessories.html#safety |title=Safety Accessories |access-date=13 September 2006 |last=Bluejay |first=Michael |work=Bicycle Accessories |publisher=BicycleUniverse.info| archive-url=https://web.archive.org/web/20061008024853/http://bicycleuniverse.info/eqp/accessories.html| archive-date= 8 October 2006 | url-status= live}}</ref> Bicycle lights, reflectors, and helmets are required by law in some geographic regions depending on the legal code.
