Bike Summer, also known as Pedalpalooza, is a months-long cycling festival in Portland, Oregon, United States. The festival was established in 2002 and features hundreds of themed events. Organizers have described Bike Summer as an "open source festival" because of its inclusive nature, with activities held from June through August. Participants sometimes wear costumes.
The cycling advocacy group Shift 2 Bikes is among organizers. The 2020 event was cancelled because of the COVID-19 pandemic. There were Star Wars- and Taylor Swift-themed rides in 2021. The 2022 event included a new Native and Indigenous Pedalpalooza. There was a "Pure Moods" ride in 2025. There have also been rides with themes based on Dr. Seuss, Star Trek, and The Big Lebowski.

Thank goodness present-day Portland, where swarms of bike-riding grown-ups take to the streets all summer long for Pedalpalooza's hundreds of themed rides, sees the silly lie in that.
