This unique, nearly hour-long film intimately explores the ardent obsession that riders from all walks of life share with this unfamiliar and demanding style of cycling.

Primarily focused on the city of Los Angeles, renowned for its car-dominated roads, Fixation delves into the reasons why these riders choose to embrace such a complex and arguably risky form of cycling. Calling itself a 'fixed gear bicycle film', it successfully encapsulates the thriving local scene's energetic spirit, while also unearthing global perspectives which adds a multidimensional facet to the subject of fixed gear cycling.

Featuring interviews with riders, store owners, and street-side spectators, Fixation provides a thoroughly comprehensive perspective on the lifestyle embraced by these cyclists - from both within the subculture and those looking in from the outside. The documentary vividly illustrates the riders' passion, dedication, and borderline obsession with the high-speed, adrenaline-filled world of fixed gear bikes. How within this world, the bike becomes more than a mode of transportation, it becomes an avenue for self-expression, a tool for navigation, and a source of unadulterated exhilaration.

Accompanying the individual narratives, we get a ground-level view of the intense races, known as alley cats, as the riders pedal furiously through the city's relentless traffic. The splendid cinematography and slick editing perfectly capture the hauntingly beautiful street scenes, shedding light on the delicate balance that the riders strike with the urban landscape.

Given the non-fiction genre, the documentary artfully weaves together the themes of risk, freedom, and the enticing thrill of the ride without focusing solely on the bike as a machine. Instead, Fixation takes a more philosophical approach, using the fixed gear bike as a metaphor for life’s constant motion. Life is like a fixed gear bike—you can’t coast, you're always pedalling, always moving forward—are sentiments expressed by the engaging and diverse cast of riders.

In doing this, it asks incisive questions about whether this niche pastime is a fleeting trend, or if it has the potential to greatly influence the future of urban mobility.

Where Fixation shines most is its efforts to humanize this urban subculture, shedding light on its transformative power and impact on its active participants. By doing so, it gives a voice to a sector of society often overlooked and enables viewers to gain a fresh perspective of the dense urban landscape, challenging what we understand about our cities, and how we navigate them.
