This easy-to-use double stroller and bike trailer has everything you need to bike or walk with your children. Quickly hitch up to your bicycle when you're ready to ride. And when you reach your destination, simply move the stroller wheel from its stowed position on the tow bar to convert the carrier to a 3-wheel stroller. You and your toddlers can enjoy a healthy, active lifestyle with this child carrier.

Bike Trailer Innovation

The ball-and-socket design of Thule's ezHitch system makes a flexible connection between your bike and the trailer. This means that as your bike leans into corners, the bike trailer stays more upright because the bike and the trailer act independently, preventing twisting of the tow bar. In addition, if your bike falls over, the flexible connection will allow the trailer to remain upright. This hitch system also stabilizes the bicycle trailer and helps to prevent the trailer from pulling or pushing on your bike as you turn, so you have a smoother ride.

Installation of the ezHitch is simple. If there is a quick-release skewer on your bike's rear wheel, then replace it with the included skewer and hitch cup. If you have a solid axle, then remove the nut from the axle to install the hitch cup. The hitch cup can be left on your bike even when you're not towing the trailer.

The ezHitch system allows you to quickly connect your bike to the child carrier.

Thule Coaster XT hitch arm secured in hitch cup

To connect the trailer to your bike, slide the end of the tow bar into the hitch cup and secure it with the locking pin. The included safety strap acts as a backup connection for the hitch in case the trailer accidentally disconnects from your bike.

Thule Coaster 2-piece flag and reflectors

An extra-tall safety flag slides into the sleeve on the rear of the trailer. And the included reflectors mount on the trailer's wheels. The flag and reflectors make it easier for the trailer to be seen as you ride.

3-Wheel Stroller Setup

Transform the bike trailer into a stroller when you reach your destination. Push the button on the tow bar, and move the tow bar back so it slides through the bracket at the front of the carrier. Slide the bar into the second bracket in front of the rear wheel and pin it into place.

Then remove the stroller wheel from the stored position, flip it over, and insert it into the tow bar. Secure it using the pin and clip. The sturdy wheel pivots so that you can navigate easily over uneven terrain, making tight turns a breeze.

Safe Construction

This carrier is designed with your children's safety in mind. The anodized aluminum frame of the carrier forms a roll cage around your precious cargo. Anodizing adds a strong surface coating that prevents rust while retaining the lightweight quality of the aluminum.

The durable, polyurethane-coated polyester fabric is free of harmful chemicals, and the UV-protected side windows are made of phthalate-free polyurethane, which complies with the European Oeko-Tex Standard 100 for safe textiles. The reflective trim increases visibility in low-light conditions so that drivers, pedestrians, and bike riders can see you coming.

Comfortable Ride

The Thule Coaster XT keeps your children comfortable as you travel. The hammock-style seats and padded, 5-point restraint harnesses help cushion your children and keep them safely inside the carrier. And the large, tinted side windows let you check on your children as they enjoy the view.

You can use the included weather cover with the screen alone to keep out bugs and debris or with the rain cover to shield your babies from wet or windy weather. An attached sunshade helps to keep your babies out of direct sunlight and can be fastened to the back of the carrier when it isn't needed.

Parent-Friendly Design

The large rear cargo compartment is perfect for storing a diaper bag or snacks, and the carrier has a mesh pocket inside the cab for organizing smaller stuff like toys or wipes.

The hand brake has a large knob on the end to make it easy to grasp. Simply push the brake handle down to lock the carrier in place or pull the handle up to unlock the brakes when you're ready to hit the road.

Each of the 20" black aluminum rear wheels can be removed with the simple push of a button, which makes folding the carrier easy.

Pulling red knobs to release frame latches on Thule Coaster XTThule Coaster XT bike trailer folded flat for storage

To fold the carrier, remove the push-button wheels, tow bar, and handlebar. Then pull on both red knobs in the rear cargo area to release the frame latches and give the back frame a sharp push down and inward to fold the carrier. After the carrier has been folded, place the wheels and tow bar on top of the carrier for storage.

A storage cover (sold separately) is also available to protect the carrier when it's not in use.

Absolutely love this trailer! My son and I get to go on so many adventures now! I use it for bike rides and also runs with him. It is easy to put together and handles very well. I love the extra storage in the back for snacks and extra clothes if needed. My son is also very comfy inside and loves to go fast in the trailer!


Ask the Experts about this Thule Bike Trailer For Kids

  • Can the Urban Glide be Used as a Bike Trailer
    We do have strollers and joggers that are compatible with bikes, but unfortunately the Urban Glide doesn't have any adapters to turn it into a bike trailer. Instead I recommend using the Thule Coaster XT # TH10101803 which sits at the same price range and actually comes with the ability to be used as a bike trailer. You simply remove the front wheel and the arm attaches to the rear wheel for easy transportation. Attached is a review video for the Coaster XT that you can check out.

  • Recommended Infant Sling for Thule Coaster XT Bike Trailer and Stroller
    We have just what you're looking for. I checked with Thule and they confirmed that the Infant Sling Reclining Seat for Thule Chariot Child Carrier - 1 Child - 1 Month to 10 Months # TH20101000 is also compatible with the Thule Coaster # TH10101803. This would be the correct infant sling for this bike trailer/stroller and will fit infants from roughly 1 to 10 months old.

  • Replacement Wheel for a Thule Coaster XT
    The correct replacement wheel that you will need for the Thule Coaster XT # TH10101803 is part # 40192431. The part that you referenced, part TH40102421, is the discontinued replacement wheel for the Thule Chariot jogging and walking strollers.

  • Can the Thule Coaster XT Bike Trailer and Stroller be Converted to a Jogging Stroller
    The Thule Coaster XT bike trailer and stroller # TH10101803 cannot be converted to a jogging stroller. For that you would need to go up to the next tier which is the Chariot Cheetah XT, # TH10100824-144. The Cheetah is a bike trailer, regular stroller, and jogging stroller. I had a version of this and it was awesome. Going from trailer to stroller or jogger was quick and easy. Everything was well-made and durable (and I have some destructive kids, let me tell you!).

  • Does 2-Child Thule Coaster XT Come Ready to Attach to a Bike
    The 2-Child Thule Coaster XT Bike Trailer and Stroller # TH10101803 does come ready to attach to a bike. It uses what is called an ezHitch system to allow the stroller to be "towed" by your bike. To go along with this stroller I do recommend the Transparent Rain Cover # TH20110700 just in case you get caught in wet conditions. I've added links to video reviews for you to check out as well.

  • Replacement Bike Trailer Suggestion For The Thule Coaster XT
    The Replacement Wheel Assembly for Thule Coaster XT # 40192431 that you reference for the Thule Coaster XT Bike Trailer and Stroller # TH10101803 is the correct replacement, however it is no longer available online for purchase. With that being said, the best option I can offer is a full replacement. Something similar to the Thule Coaster XT # TH10101803, is the Thule Chariot Cheetah XT Bike Trailer, Stroller, and Jogger # TH10100426-143. The Thule Chariot Cheetah XT # TH10100426-143...

  • Diameter of Thule Replacement Bike Adapter ezHitch Cup
    I went out to the warehouse with the digital caliper # PTW80157 and found that the diameter of the Replacement Bike Adapter ezHitch Cup # 50103033 is 1.14" which is just over 1-1/8". This adapter is designed for the Thule Coaster XT Bike Trailer and Stroller # TH10101803 so if you have something else this may not be compatible.
