Alan Stulberg and his team from the Revival Cycles shop have created a custom bike for a prototype two-cylinder boxer engine. The bike is a one-of-a-kind with 134 nine-millimeter titanium rods that create an intricate lattice structure. Dubbed the Birdcage, the bike is inspired by BMW motorcycles from the 1930s and racecars from the early 1960s.
Riders have a clear view of the engine and drive linkage, which was strategic on Stulberg’s part.
“I wanted to establish the engine as the absolute most extraordinary feature of the build,” he says, according to BMW Motorcycles.
Stulberg also incorporated asymmetry in the design with staggered cylinders and other components strategically installed asymmetrically. The team also focused on capturing unique wheels which use 23 inch slicks from Dunlop. Stulberg says they are the only ones in the world to have them.
“This new giant boxer had me dreaming of the power and torque it must be capable of right away,” says Stulberg, according to Revival Cycles. “I always wanted to build a frame in Birdcage style, inspired by the racecars of the early 1960s.”
The design process for this bike consisted of years of envisioning. Stulberg says it laid dormant in his mind for many years, and when the creative process finally began, it took six months to create the concept’s drawings and lines. Then, he decided on the wheel and tire sizes prior to creating the CAD drawings for the mechanics of the bike.
The minimalistic look is achieved by eliminating a headlight, dash, front brakes, and side mirrors. According to New Atlas, gearshifting appears to occur via a suicide hand shift on the right side of the bike.
Although most likely not built for riding on the highway, this bike will surely catch the eye of bike connoisseurs around the world.
