Product Description The iBert safe-T-seat is a front mounted child seat that has many benefits over the alternatives. It allows you to have more interaction with your child while riding; the child has a better view; your bike will have better center of gravity; and it is easier and safer to load your child into a front mounted vs. a rear mounted seat. The iBert is designed so you can pedal your bike without hitting your knees on the seat and is easy and fast to install. The safe-T-seat is designed for children 4 and under. The minimum age is 12 months since the child needs to be able to sit up well and hold the weight of a helmet. The maximum height of the child using the iBert seat is 42 inches. Kids taller than that will be uncomfortable. The max weight for the seat is 38lbs. Installation takes minutes. You will need at least 3/4 inch of usable stem in order to attach the seat. Amazon.com The iBert safe-T-seat was designed on the premise that all child bike carriers are not created equal. The safe-T-seat lets you interact with your child while riding. Equipped with a three-point harness and lap bar, the safe-T-seat puts your child at the front of the bike, where she is safe, comfortable, and entertained. The front-mounted location is more fun than a bike trailer, which limits your child’s view while putting her in the path of rocks, dirt, and other annoyances. It’s also more gratifying than rear-mounted seats, as it lets you interact more with your child while providing a better center of gravity. And unlike many traditional front-mounted seats, the safe-T-seat sits high enough to stay clear of your knees while pedaling, installs easier, and sports more safety features. Designed for children four and under, the safe-T-seat features iBert’s patented stinger assembly system, which attaches and removes easily from almost any bike. The stinger system sits higher than other seats and is smooth on the bottom. Even if you’re extra tall and hit your knees on the bottom of the seat, they’ll just glide along the seat’s smooth bottom edges. The safe-T-seat is safe for children up to 38 pounds and 42 inches tall. Kids taller than 42 inches will be uncomfortable. Parents will need at least 3/4 inch of usable stem to attach the seat.
