The Polisport Standard Frame Holder provides a dedicated frame-mount connection for compatible Polisport child seats. It is designed for round bicycle frames measuring 28–40 mm in diameter, with 80 mm of usable frame length required for installation, so check your frame carefully before ordering.
Once fitted, the holder lets you remove the compatible seat quickly by pressing the release button while lifting the seat up and backwards. A safety indicator device helps confirm that the seat is correctly assembled before you ride, while the internal rubber pad helps protect the frame during use.
The holder also includes an opening in its rear metallic section to help prevent brake cables being pinched. With the mounting kit and tools included, it is a practical choice for replacing an existing holder or setting up an additional bike for the same Polisport child seat.
Ideal for families who want to mount a compatible Polisport child seat securely on a second bicycle or replace an existing frame holder.
