Polisport Bubbly Maxi Plus CFS

Pros

  • Tool-free knob clamp and a seat that slides fore and aft adapt the fit to both child and bicycle.
  • Footrests with 4 height positions and a 3-point harness adjustable to 2 heights grow with the child within the 9-22 kg range.

Cons

  • It needs an ISO 11243 rack 120-175 mm wide with 10-22 mm round tubes and a minimum 27 kg load rating: rack appearance alone does not confirm fit.
  • The 3-point harness and upright shell are simpler than reclining or 5-point alternatives: compare restraint and sleep needs.

Polisport Bubbly Maxi Plus CFS is a practical rear seat when the bicycle already has a compatible ISO 11243 rack. The tool-free clamp slides fore and aft, helping balance child space and bicycle fit, while four footrest positions and two harness heights serve children from 9-22 kg. Compatibility is the deciding factor, not the rack’s appearance: it must be 120–175 mm wide, use 10–16 mm tubes and carry the required load. The upright shell and three-point harness are simpler than reclining or five-point alternatives, so consider sleep and restraint preferences too. Choose this CFS version for a verified carrier; it is not a universal rack attachment.
