Polisport Bubbly Maxi Plus CFS

Pros / Cons
Pros
- The carrier clamp installs without tools and slides fore and aft to balance bicycle fit with rider and child space.
- Four footrest positions and two harness heights extend useful adjustment within the 9-22 kg range.
Cons
- It requires an ISO 11243 rack 120–175 mm wide with 10–16 mm tubes, so rack appearance alone is not enough to 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.
