Dreams about riding a bicycle often symbolize your journey in life and your sense of control over your direction and choices. The presence of two others on the bike with you suggests that you may be sharing responsibilities or experiences with others in your waking life.

Dropping the pizza could represent a feeling of loss or disappointment regarding something you were looking forward to or trying to achieve. Pizza often symbolizes sharing and communal experiences, so this may indicate a disruption in a social or collaborative effort.

Overall, your dream may be reflecting your current relationships and shared goals, as well as the challenges that can arise when navigating these dynamics. It might be helpful to consider how you feel about the support you receive from others and whether there are any areas where you feel things could go more smoothly.
