The Hauck Rapid 4 is a variation of the three-wheeler
Hauck Rapid 3, but with four smaller wheels designed for urban surfaces. You can fold it with just one hand by simply pulling up the strap on the seat. The non-reversible seat is fully reclinable. The stroller is either sold separately, in a travel system with a car seat (Hauck Rapid 4 Shop´n Drive), in a 2in1 stroller system with a carrycot (Hauck Rapid 4 Duo Set) or, most commonly, in a 3in1 stroller system with a carrycot and a car seat Hauck Rapid 4 Trio Set. The Rapid 4 was also released in the popular Disney edition.
