On Kickstarter, Mission Bicycle Company is trying to raise funds to create Lumen, a bike thats gray by day but glows bright white when a car or anything else shines some light on it. The bikes frame and rims are coated with hundreds of thousands of retroreflective spheres, which send light that hits them directly back to where they came from. Backers can receive a single-speed city bike for $1,245 or an eight speed for $1,595. Those who know their way around a bike may instead want to opt for a less expensive option, receiving just a frame and fork for $499.
