Abstract: A bicycle protective cover is used to protect the bicycle from the elements. It includes at least one pair of horizontal zippers situated near the crossbar of the bicycle and preferably two such pairs one near the front and one near the rear of the crossbar. It includes at least one pair of diagonal zippers situated near the bicycle wheels and preferably two such pairs one near the front wheel and one near the rear wheel. The front diagonal zipper pair is situated near where the front wheel meets the fork. The rear diagonal zipper pair is situated near where the rear wheel meets the bicycle gears. The zippers in each pair of zippers are aligned with one another so that locking devices can be inserted through the entire width of the cover.
