I'm researching strollers and noticed that a few of the models I'm interested in come in both 3-wheel and 4-wheel configurations. Specifically, Baby Jogger City Mini and City Select, Britax B-Agile, and iCandy Apple.
We live in an urban area where it doesn't make sense to own a car. So we do a lot of walking on cobblestone sidewalks that are often uneven. Some paved paths. A lot of off-road walking with the dog. We're not really jogging/running. And need to be able to get on/off transit easily.
If you have experience with any of these strollers -- what are the advantages/disadvantages of having 3 wheels vs. 4? Do you have one configuration and wish you had another?
