Using the Burley DLite X Child Trailer is a breeze. First, when you want to use it as a bike trailer, use the quick receivers to easily attach the tow bar. You can adjust the seat recline to 3 different positions to make your child as comfortable as possible. If you switch to strolling, the included 1 - Wheel Stroller Kit allows for a fast transition. When it comes to maintenance, the premium seat pads have a removable headrest that you can take out and clean easily. Keep the trailer protected from scratches with the skid guard. In wet conditions, the water - resistant cover and zippers will keep your child dry. For ventilation, open the front cover and rear window. Always make sure the weight limit of 75 lbs is not exceeded. When not in use, store it in a dry place. If you want to use it as a cargo trailer, just detach the seat. Enjoy your adventures with this amazing trailer!
