Additional specifications:


The Bubbly MIK HD is a rear-mounted child bike seat that can be directly attached to bikes with a MIK HD rear rack. MIK (Mounting Is Key) is a rear rack mounting system that makes it easy to change bike accessories. The Polisport Bubbly Maxi Plus MIK HD features the new MIK HD adapter plate. This system allows you to click the bike seat onto the rack in seconds, without any tools.

What is MIK? MIK (Mounting Is Key) is a rear rack mounting system that makes it easy to change bicycle accessories. The system was launched in 2017, and the developers were in contact with Polisport from the outset because they wanted a bicycle seat with the MIK system. Polisport certainly saw the advantages of the system's ease of use, but safety is always a priority when transporting children. A more robust system was therefore needed, and we continued to develop it together, resulting in the MIK HD.
