Selling 2 Trail-Gator systems. Both are in awesome shape and have all needed equipment for the Parent's bike and the kid's bike (seat post kit, receiver, fork clamp set, u-bolt set, etc.). One is blue and one is red. $65 each The Trail-Gator Bicycle Tow Bar converts an ordinary child's bike into a safe, towable trailer bike, whenever desired. To ride attached, simply unclip the tow bar from the stored position on the adult bike, extend it, and connect it to the receiver, which is mounted on the child's bike. When the child's bike is connected, the front wheel is lifted off the ground and a stabilizing bar prevents the handlebars from turning, leaving the adult in control of steering. Children can choose to coast or pedal while they are being towed, making the ride much easier for them. Attachment and detachment can be done at any time and only takes seconds. No tools are necessary and no parts need to be removed from either bike. The tow bar weights just 5 pounds.
