Ignis Hybrid operation and roof bike rack and 4×4

Hello Suzuki community! I am interested in a new Ignis and I wonder at what speed the hybrid switches to or from the petrol mode? Is it possible to only step-tempo or also to speed 30 with the battery or does the hybrid only support when starting? And if I am already there: Did you order the roof bike carrier with or bought separately? If so which one? Is the 4×4 drive often or rather rarely ordered? Thank you for your answers.
