Polisport Bilby Maxi RS

Pros

  • The recline and high sides give more comfort on longer rides than a simple upright rear seat.

Cons

  • Frame mounting needs a strict tube check and is not a match for carbon frames or rear suspension.

Polisport Bilby Maxi RS is the stronger shortlist fit if you want a rear frame-mounted seat with a real recline, not just a basic upright shell. The 20 degree tilt and higher side support matter most for longer nursery runs or leisure rides where your child may doze, while the frame mount keeps it independent of a rear carrier.

The fit check is strict. Polisport specifies round or oval frame tubes from 28 to 40 mm, 80 mm of mounting space, 66-71.1 cm wheels, and a 9-22 kg child range. Skip it for carbon frames, rear suspension, or any bike where the clamp area, cable routing, or adult leg clearance is uncertain.
