A Fixed Wheel is best for running or jogging, as it provides a straight and stable ride. Fixed Wheels are also ideal on trails or in sand, as that wheel is not going to get stuck. However, to turn a corner, you''ll have to lift the front wheel and spin on the rear wheels. If you'll be using your Stroller only for running or mostly off road, then a fixed wheel is for you. But if you need an all-purpose Stroller that will also let you run with it on occasion, then check out our Swivel with Lockout Strollers.
