Persons engaged in cycling are called cyclists, bikers, or sometimes bicyclists. They typically either dress for where they are going, or for the cycling, sometimes having another set of clothing with them, or arranged.

Some bicycles are sold with (electric) motors (e-bikes), or other motor assistance.
