The Polisport Bubbly Maxi Plus FF is a rear frame-mounted child seat for children from 9 kg-22 kg/19.8-48.5 lb. Polisport documents a three-point harness, four-position footrests, a frame holder that releases with a button and compatibility with 28–40 mm round or oval frame tubes. It is listed for 66-71.1 cm/26-28 in bikes and needs 105 mm of mounting space; an e-bike-compatible mounting plate is included. The seat works only when the bicycle geometry and child both fall inside those limits, so check tube shape, clearance and weight before purchase. Its quick-release holder makes removal between rides easier, but a second frame holder is a separate purchase if you want to move one seat between bikes.
