The WeeRide Co-Pilot is just the thing for a child who wants to tag along with Mommy or Daddy, but doesn't have the legs for it! Your child can pedal to help you along, or just coast and enjoy the scenery. Either way it's fun for BOTH of you! Sturdy construction construction - just like a regular 20" bicycle with regular handlebars, seat, and pedals. Attaches easily and quickly to almost any bicycle with a seatpost, and folds up for storage when not in use. And it even comes with a safety flag to alert motorists. The Co-Pilot is great for the whole family, nothing says togetherness like a family bike ride !
