Stay visible when it's dark

Protected bike infrastructure doesn't exist in most of the USA, so visibility is a key part of staying safe.  It can be even more difficult during the darker winter months.  Children's bikes are lower to the ground.  Cars, SUVs and trucks have grown larger, which creates a bigger front blind zone.

The Bike Beam is better than a bike safety flag.  It shines light from a large area as a bike totem so that you can be easily seen from a distance.  Have fun with the changing colors and make those you ride past smile.

Light doesn't fit on

Through-axle wheels, no bike rack

On wheels with a through-axle, there is unfortunately no location to mount the metal bracket or attach the rack mounting straps.

    We put our bike beam lights on our Burley trailer, and love the fun way it makes us more visible at night.
