Koolah RMS is the rear child bicycle seat for bicycles equipped with luggage carriers. Up to 22kg, this child sear mounting system is the perfect solution if you are looking for a seat that can´t be stolen ? since you need tools to install and remove the seat. Once the base is firmly attached to the carrier, the seat is fixed or removed with just a twist from a screw. Straps included: when riding without the seat on, the base doubles as a practical object carrier with the help from its straps. Mounting kit required for assembling the seat is included.
