Polisport Bubbly Maxi Plus 29

Pros

  • The quick-release frame mount avoids depending on a rear rack, with green indicators confirming correct fitting.
  • TÜV GS – EN 14344 compliant shell with footrests and wheel guard included.

Cons

  • Needs round or oval frame tubes from Ø28 to 40 mm with at least 105 mm free; it does not fit every frame.
  • The 9-22 kg range leaves the infant stage below 9 kg uncovered.

Polisport Bubbly Maxi Plus 29 is a rear frame-mount seat built for small frames and 29ers: it clamps to frame tubes of 28-40 mm and carries children up to 22 kg. The quick-release frame holder with three-position seat adjustment is the reason to pick it when a rack seat cannot fit your bike. Before buying, measure the frame tube diameter and check heel clearance and rear-wheel clearance with the seat mounted.
