My husband and I reviewed a few children's bike seat and we were getting negative reviews about the seats that attach behind the bike. Apparently it causes some imbalance when you use the seat that attaches behind the bike. We found this Kangaroo child seat from WeeRide and we strongly agreed that having the child in front where you can see him at all times was the safest. My 18 month old loves to ride along with his Daddy. The best part about this seat is that it is light weight, very nice design, and it allows the child to have a great view while riding. I would highly recommend this to anyone looking into buying a child bike seat.
