Making the world of child seats a little more accessible to everyone, and reaching the most compatibility possible between bicycle manufacturers and Polisport front seats, we have developed this new Ahead Adapter – a sturdy little bracket that allows you to mount your Polisport seat to bikes with threadless stems. The Ahead Adapter is designed to accommodate adjustable stems, e-bikes with a monitor or controller at the top of the stem, and MTB with 1” 1/8 stems. The required installation space is only 5mm.
