A stroller is designed for active use and rugged terrain. It has a single front wheel and all three wheels are generally larger than the wheels on other types of strollers. Some models have a fixed front wheel, some have a swiveling front wheel, and some have a front wheel that swivels and can also be locked in a fixed position. Depending on the model, a jogger stroller may also be designed to accommodate an infant car seat.
also called: jogger stroller
