Hamax, a Norwegian company specializing in winter products and bicycle accessories, has introduced a versatile new accessory for bicycles that acts as a luggage rack, a bike bag, a child seat and a basket. Called the Hamax PLUS, the contraption uses a series of snaps, allowing the user to make necessary changes without using tools. Hamax, which is best known for its sleds, belongs to Katalysator, a Norwegian conglomerate that also controls Madshus and Alfa.
