Ever noticed that real jogging strollers have fixed front wheels rather than the customary swiveling wheel? The reason for this is because when you are jogging it’s much easier to keep a stroller in line and going straight when the wheel is fixed. The stroller is much easier to keep under control.
The best example of this being nessesary is to consider jogging with a stroller than didn’t have a fixed front wheel. If you were to roll the stroller over a small divet in the road or over a small rock or even change in the pavement the swivel front wheel could easily veer off to one side or the other temporarily putting the stroller into a state where it’s not being controlled.
Another common reason jogging strollers have fixed front wheels is because it’s really hard to jog with good form while pushing a stroller. You almost always have to have at least one hand on the stroller or stroller strap so that you can keep the thing under control at all times. With a swivel front wheel you typically have to use your hands on the handlebar more often as it slightly veers one way or the other.
The thing is that even swivel wheels that lock into one position simply aren’t locked in position good enough. There’s always some jiggle in the wheel one way or the other. This is fine for walking but when jogging the stroller can easily veer one way or the other depending on the topography or the way the stroller is aligned.
With a jogging stroller that has a front wheel fixed in one position you don’t have the jiggle and the stroller won’t veer nearly as much if at all. This is important as you will be traveling farther and faster and won’t want to have your handles on the handlebars at all times.
A real jogging stroller will almost always have the front wheel that doesn’t swivel. You can jog without it but it does make the experience better. Just keep in mind that with a fixed front wheel you give up a lot of conveniences of a swivel front wheel. For this reason people who own jogging strollers typically also own a main stroller that they use for other purposes. Not always but this is common.
