iBert Safe-T-Seat Child Seat
You know how boring the back of somebody's head looks after a few hours of pedaling behind them. So don't put your kids through the same agony. Put them in the iBert Safe-T-Seat instead. Not only will they get a better view, you'll have more interaction with your child. Improves your center of gravity, makes it easy to load/unload your child and is less expensive than rear-mounted seats.
