    摘要： A bicycle and a bicycle folding method which allow a rider to easily and securely fold and unfold the bicycle is described. The bicycle has a front wheel and a rear wheel; a saddle on which a rider rides; a pair of pedals to which the rider imparts drive force; a first frame for holding the front wheel in a rotative manner; a handle for changing the direction of the front wheel; a second frame for holding the rear wheel in a rotative manner; and a linking portion for linking a linking member of the first frame with a linking member of the second frame, wherein the first frame and the second frame are brought close to each other by the rider's lifting the linking portion with the front wheel and the rear wheel kept in contact with the ground, thereby folding up the bicycle with the front wheel and the rear wheel overlapping each other in at least one portion.
