Polisport Koolah Rear Child Bike Seat
Make everyday family rides easier with the Polisport Koolah Rear Child Bike Seat. Designed for children from approximately 9 months to 5 years old and weighing up to 22 kg, the Koolah is a practical, comfortable and secure solution for bringing your little passenger along for the ride.
One of Polisport's most popular child bike seats, the Koolah features a frame-mounted design, adjustable footrests, a 3-point safety harness and increased side and foot protection. It's also suitable for bicycles with or without a rear carrier, making it a versatile choice for a wide range of family bikes.
Comfortable & Adjustable as Your Child Grows
The Polisport Koolah is designed to adapt as your child grows. The adjustable 3-point safety harness offers two height positions, while the footrests can be adjusted across four positions to provide a comfortable fit for different heights.
The armrest-shaped sides provide a comfortable place for your child to rest their arms while helping protect their hands. Increased lateral protection and large foot guards provide additional coverage around your little passenger during the ride.
Frame-Mounted for Greater Compatibility
Unlike carrier-mounted child seats, the Polisport Koolah attaches directly to the bicycle frame and can be installed on bikes with or without a rear luggage carrier.
The frame holder is compatible with round and oval tubes from 28 to 40 mm and allows the child seat to be quickly attached or released at the push of a button. This makes it convenient when you need to switch between family rides and solo cycling or remove the seat for storage.
The seat can also be moved backwards or forwards across three positions, helping you find the appropriate setup according to your bicycle and child's size.
Designed with Safety in Mind
The Koolah includes a childproof safety buckle, additional frame safety belt and increased foot protection designed to help prevent contact between your child's feet and the bicycle wheel.
A rear reflective sticker provides additional visibility, while the seat complies with TÜV GS – EN 14344 standards.
