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.
