The bike trailer for kids attaches to the frame of our adult bikes to provide seating for one or two children (100lb. limit total). Please request an adult bike (no tandem bikes) and we will attach the cart to the appropriate adult rental bike. The cart features seating for one or two small children with 5 point seatbelts and a mesh and clear vinyl canopy. Attachable bike trailer includes a behind-the-seat storage area. Toddler helmet rental is available upon request. Adult bike is not included.
