Whenever we go to our favorite beach destination, Jekyll Island, we always spend a day riding bikes around on their many trails. The first few times we went was before my son was born and when we have gone with him, he was small enough to sit in a child seat on the back of my husbands bike. On this last trip, he was 6, too big for a child seat yet too small of keep up on the trails for several miles. We went to the bike rental location and asked them what our options were. They recommended we rent a Trail-a-Bike. I had never heard of these before but it worked perfectly.
Trail-a-Bikes were first marketed in 1986. They are basically a small child size bike that has a back wheel and a long bar on the front instead of a front wheel. The bar attaches to the adult bike with a universal hitch with a full 360 degree range of motion. It has pedals and and a handle bar like a regular bike. The child can pedal to help the parent out or if they get tired can stop but the parent will have to pick up the slack. The handle bars are stationary and are there just for the child to hold on to. The seat is adjustable so it can be positioned for the child to comfortably reach the pedals. The recommended weight limit for one of these is 85 pounds.
This worked really well for us. My son got to feel like he was on a regular bike like the rest of us but could also rest when he wanted to with out us having to stop. This is a great item for parents who love to bike but have children at the in between stage between a baby seat and being able to go long distances on their own.
