Learn step-by-step how to convert your Baby Jogger City Select 2 from a single to a double stroller using the second seat kit, and explore its five configurations.

The Baby Jogger City Select 2 is designed to grow with your family. Whether you're expecting a second child or need to accommodate a toddler and a newborn, converting your stroller from a single to a double is a straightforward process. In this guide, we'll walk you through installing the second seat kit, adjusting the seat positions, and exploring the five configurations that make the City Select 2 one of the most versatile tandem strollers on the market.

Before you start, ensure you have the correct second seat kit for your model. The City Select 2 uses the same seat as the original City Select, but it's always wise to verify compatibility with your specific stroller. Also, keep in mind that the second seat kit includes the seat frame, fabric, and canopy, but you may need to purchase the car seat adapter separately if you plan to use an infant car seat in the lower position.

What's in the Second Seat Kit?

The second seat kit for the City Select 2 typically includes the seat frame, seat fabric, canopy, and all necessary hardware. The seat is designed to be interchangeable with the main seat, allowing you to use it in either the front or rear position. This flexibility is key to creating the five configurations that the City Select 2 offers.

If you're using an infant car seat, you'll need to purchase a separate car seat adapter. For example, the baby jogger car seat adapters for city mini® 2 double and city mini® GT2 double strollers are for a different model, so ensure you select the correct adapter for the City Select 2. The adapter clicks into the same mounting points as the second seat, allowing you to attach a compatible infant car seat.

  • Check the compatibility of the second seat kit with your City Select 2 model.
  • Consider purchasing a car seat adapter if you plan to use an infant car seat in the lower position.
  • Keep the original seat's hardware in a safe place; you may need it if you switch back to single mode.

Step-by-Step Installation of the Second Seat

Start by removing the existing seat if you haven't already. To do this, locate the release levers on the sides of the seat frame and pull them simultaneously while lifting the seat upward. Once the seat is off, you'll see the mounting brackets on the stroller frame.

Next, take the second seat and align its mounting points with the brackets. You'll hear a click when it's securely attached. Make sure the seat is locked into place by giving it a gentle tug. Then, attach the canopy to the seat using the provided snaps or clips.

If you're installing the seat in the rear position, you may need to adjust the front seat to a more upright position to allow enough legroom for the rear passenger. The City Select 2 features adjustable leg rests and recline positions, so you can customize the comfort for each child.

  • Always ensure the seat is locked in place before placing your child in it.
  • For a newborn in the lower position, use the fully reclined seat with the infant insert if available.
  • Practice folding the stroller with the second seat attached to get used to the added weight and bulk.

Exploring the Five Configurations

The City Select 2 is known for its five configurations, which allow you to arrange the seats in various ways to suit your needs. In single mode, you can use the main seat in the front or rear position. In double mode, you can have both seats facing forward, both facing rearward, or one facing each direction (forward and rearward).

This flexibility is especially useful for siblings with different preferences or for keeping an eye on a newborn while an older toddler faces forward. To change the orientation, simply lift the seat out and reattach it in the desired direction. The seat also adjusts to multiple recline positions, including a near-flat position for newborns.

When using the City Select 2 as a tandem stroller, remember that the lower seat has a weight limit, typically around 35 pounds, while the upper seat can hold up to 45 pounds. Always check the manufacturer's guidelines for your specific model to ensure safe usage.

  • Use the rear-facing position for the lower seat to interact with your child.
  • For older toddlers, the forward-facing upper seat offers a better view.
  • The near-flat recline is ideal for naps on the go.

Tips for Daily Use and Maintenance

Once your City Select 2 is set up as a double, you'll appreciate its maneuverability, but there are a few things to keep in mind. The stroller becomes longer, so turning in tight spaces may require a bit more effort. Practice navigating doorways and store aisles to build confidence.

Regular maintenance is essential to keep the stroller in top condition. Wipe down the frame with a damp cloth, and check the wheels for debris. If you use the stroller in wet weather, consider adding a weather shield for city mini® GT2 strollers (though this is for a different model, you can find compatible accessories for the City Select 2). Also, the storage basket for city select® stroller is a handy accessory to keep essentials within reach.

  • Check the seat attachments periodically to ensure they remain secure.
  • Clean the seat fabrics according to the care instructions to maintain appearance.
  • Invest in a stroller organizer that attaches to the handlebar for easy access to snacks and toys.

Converting your City Select 2 from a single to a double stroller is a simple process that unlocks a world of versatility. With the second seat kit, you can create five different configurations to suit your family's needs, from a tandem stroller for siblings to a travel system with an infant car seat. By following the steps outlined above and taking care of your stroller, you'll enjoy years of use as your family grows.
