Children's Retractable Bicycle Traction System Bike Towing System Features: The children's retractable bike traction system allows you to tow your child safely on bike rides. It helps children and adults maintain control while riding over bumps or puddles. The system can assist in pulling kids up hills when needed. This product is designed for occasional assistance, not for continuously dragging the child. The traction unit is a spring-loaded case that mounts behind the seatpost and under the seat. Positioned this way, it enables smooth towing of your child's bike. Inside, a thick elastic band extends up to 2.50 meters and features a double hook for secure attachment. It is easy to use and enhances safety during rides. The elastic band provides cushioning, improving comfort and reducing the impact of bumps. While towing, some resistance is expected, but it remains manageable. Ideal for helping children during longer rides or when they need extra support. Very light and compact design—fits easily in a large pocket or backpack. Kids can attach it to their bike quickly. The system can be disassembled for storage or transport. Package includes: - 1 spring-loaded case - 2 straps for quick attachment to seatpost - 1 heavy-duty elastic strap, 2.50 m long, pre-tensioned - 1 double hook for attaching to the handlebar of the towing bike Maximum towing weight limit: 90 kg
