Which set does this flywheel-like assembly belong to?
This assembly consist of two parts. Well, technically, four parts, as there are two Technic 2L pins in Black, but these come in multiple sets so out of interest.

Top one in Orange is Flywheel Fairing Lion Shape with Gold and Blue Feathers Pattern (70102)



And the bottom one is Flywheel Plate 2 x 8 with Metal Flywheel and Dark Azure Tire (Chima Rip Cord Base)



Top part was available only in 70102, CHI Waterfall set. And the bottom one was included in 22 sets.
