CatEye's Go Kit gives you what humans have been searching for since the Paleolithic: light and knowledge - all at an affordable price! For seeing the road and staying safe, you get CatEye's fine EL135 headlight and Omni 3 taillight, plus for tracking all your key riding stats, CatEye includes their 7-function Velo 7 computer. To light the way, the compact headlight with its no-tools universal quick-release handlebar mount boasts 3 super-bright LEDs and a wide beam. Meanwhile, for the back, CatEye's Omni 3 with their FlexTight mount and included clothing clip can be placed almost anywhere and it uses their Omni Directional Technology for 360 degrees of visibility and boasts 3 ultra-bright LEDs plus 3 modes. Then, making every ride even more fun is CatEye's Velo 7 computer that displays your speed, distance, ride time and more on its easy-to-see screen. Like their lights it's easy to mount (to the stem or handlebars) and simple to operate. You'll love the large, bright display, and single large button for easily and quickly changing modes to see how your rides are going.
