In a world with an uncertain future, do you imagine for the best- or for the worst-case scenario? Twelve writers tackle extreme solarpunk utopias and apocalyptic or political dystopias—and the grey areas in between—in Biketopia, the fourth volume of the Bikes in Space series of feminist science fiction stories about bicycling. Whatever your own future or present reality, these stories will motivate and inspire you to envision something different . . . and maybe even better.
