Usage Tips: Children's Retractable Bicycle Traction System Bike Towing System Child Retractable Features: The children's retractable bike traction system allows you to tow your child while cycling. Children and adults can maintain steering control and ride over bumps or puddles. You can use the system to assist kids uphill. This is the perfect solution for occasional assistance. These are not intended for continuously dragging children. Some parents attempt to use this like a tracking device and never release the tension, but responsible use is recommended. The retractable unit is a spring-loaded box that mounts behind the seatpost and under the seat. Positioned this way, it enables towing of your child's bike. Inside is a thick elastic band with a double hook for secure attachment. It is easy to use and designed for safety. Once the elastic band is extended, the maximum distance between the two bicycles is 2.50 meters. The proper spacing ensures safe and smooth riding. The elastic band provides comfort and reduces the impact of bumps, so the child is less likely to complain. While towing, the force from the child’s weight will be felt, but it remains manageable.
