Using this trailer is easy. First, make sure the trailer is properly attached to your bike. Then, place your child in the seat and secure them with the five - point harness system. When you're done using it, use the compact fold feature to flatten it for easy storage in your garage or trunk. Always check the wheels before each ride to ensure they're properly tightened. Keep the trailer clean by wiping it down regularly. Avoid exposing it to extreme weather conditions for long periods. Also, make sure the weight of your child and any cargo doesn't exceed the 75 - lb weight limit.
