Riding your bike every day is great for your body and mind. But you need to make sure you stay visible and safe at night. Lumen is a retro-reflective bike designed specifically for city riding. It integrates retro-reflection, so you will be visible on the road. All you need is direct light for your bike to start glowing. There are no batteries to rely on or an on/off switch.
Lumen returns the light directly back to its source. It has a significant reflective surface area and will keep you visible up to 1000 feet. The makers are offering one single-speed bike and two geared bikes on Kickstarter. Pretty rad if you ask us..
