A bicycle fork is the portion of a bicycle that holds the front wheel and allows one to steer. A fork consists of two dropouts which hold the front wheel axle, two "blades" which join at a fork "crown", and a steerer to which the handle bars attach allowing the user to steer the bicycle. The steerer of the fork interfaces with the frame via a headset.
On some mountain bicycles, the fork contains a set of shock absorbers. The suspension travel and handling characteristics vary depending on the type of mountain biking the fork is designed for. For instance, manufacturers produce different forks for cross-country (XC), downhill, and freeride riding.
This facilitates the loading of a bicycle upon the fork anchor, even when the skewer is inadvertently struck by a fork prong during the loading process because the fork engaging portion of the skewers retains or regains an exposed position outside of the anchor's housing.
The bicyclefork anchor 100 optionally incorporates a pivot mechanism or adjustable mounting 170 for permitting translation of the anchor 100 in a horizontal plane thereby providing a means for canting a secured bicycle's front wheel assembly and handle bars at an angle with respect to the rest of the bicycle'sframe.
The skewer assembly 122 fits within the bicyclefork anchor 100 with a slight degree of play permitting the assembly 122 to move rightwardly or leftwardly in response to forces experienced as the adjustment mechanism 145 is operated and a pre-load is applied to the bicycle prongs.

Bicycle brakes are either rim brakes, in which friction pads are compressed against the wheel rims, or internal hub brakes, in which the friction pads are contained within the wheel hubs.
Bicycle patrols are now enjoying a resurgence in many cities, as traffic congestion and pedestrian streets have limited mobility for car-borne officers.
