The Polisport Koolah RMS is a rear child seat for bikes with luggage carriers, supporting up to 22kg. It offers a secure mounting system that requires tools for installation and removal, reducing the risk of theft. The seat base attaches firmly to the carrier, and the seat can be easily fixed or removed with a screw twist. When the seat is not in use, the base serves as a practical object carrier with included straps. The necessary mounting kit is included, but the rack is not. SKU: 8998C.
