E-Bike Cruise

Add to this scene: 4 to 5 riders on modern e-bikes with a tour guide.

- Riders on visibly modern e-bikes (battery/frame design) along the most plausible route surface in the input
- Tour guide at front, professional polo, turning to engage the group
- Riders aged 40–65 in smart-casual active attire (not full lycra — premium tour vibe)
- Natural spacing, relaxed cruising postures

Match scene lighting, color temperature, and terrain texture. Riders grounded, correct perspective scale. The scene's dominant landscape remains visible.

Do NOT invent a bicycle lane or path that does not exist in the input — only place on surfaces clearly visible and traversable by bicycles (existing road, dedicated lane, wide paved plaza). If the input has no usable riding surface, return the input unchanged.
