Phil Baechler founded the Baby Jogger Company in 1984 when he realized he wanted to spend time with his infant son while enjoying his favorite pastime, jogging. When he wasn't working as a journalist, he began bringing his son along with him in his baby carriage on jogs. Standard... Read More carriages, he discovered, were not made to endure long distances, so he designed a specialized stroller that parents can use while jogging. Baby Jogger's first stroller, the Twinner, was made for two children. The Twinner and the original Baby Jogger models were both designed for serious runners, as the wheels were bolted on and neither stroller folded down. Over time, Baby Jogger released various lines of strollers that accommodate different types of joggers. Its City Select Single, one of the company's most popular strollers, is a multi-functional piece that allows parents to mix and match seats, bassinets, and car seats to fit different needs.
