This bike returns any light that hits the frame and wheels directly back to the light source.
By day the Lumen bike is a deep charcoal gray, with a slight iridescent sheen. The embedded reflective material adds a unique visual depth.
But at night is when the magic happens. With direct light, the Lumen’s frame and rims glow helping identify the rider to surrounding road users.

Designed and built in San Francisco.
