Using the Thule Cadence 2 bike trailer is easy. First, attach it to your bike using the Thule ezHitch axle mount. Make sure it's securely fastened before you start your ride. Place your children in the trailer, buckle them up with the 5 - point safety harness, and you're ready to go. You can use the extra storage space to carry snacks, toys, or other essentials for your trip. When you're done, fold it up easily for storage at home or in your vehicle. As for maintenance, keep it clean by wiping it down after each use. Check the attachment points and safety harness regularly for any signs of wear or damage. Also, make sure the trailer is stored in a dry place to prevent rust or other issues. Don't overload the trailer beyond its 100 - lb weight capacity, and always follow the international safety standards when using it with your kids.
