Suspension seatpost with multiple diameters vs Suspension Seatpost for eBike USS-SP18 (various diameters) 365/580mm

Overall winner: Suspension seatpost with multiple diameters

Key Differences

Bibike's Safort seatpost offers multiple diameter options and 50mm travel for a smoother ride and explicitly notes a maximum capacity, making it better for riders needing specific fit and lighter-weight riders. Inkesky's USS-SP18 uses a 4-link/parallelogram suspension and covers a 27.2–34.9mm range with good weight adjustability, so it's aimed at eBike users wanting multi-link suspension but may feel firmer for riders over 130 kg
