The Baby Jogger Summit X3 is the third generation of the Summit series. Summit X3 is a three-wheel hybrid suitable for running as well as for everyday use. The front wheel can be locked in a fixed position with a simple mechanism located on the handle. This makes it easy to switch between walking and jogging modes. The air-filled tires with individual suspension can handle any terrain. The seat is spacious enough even for an older child. You can recline the backrest fully. However, the leg rest cannot be adjusted. The storage space of the spacious shopping basket is expanded by the pocket on the rear part of the backrest. Adding a carrycot and/or a car seat creates a stroller system according to your needs. All accessories, including a bumper bar or a snack tray, must be purchased separately.
