This Clever Device Makes Your Bike Safer And Smarter. If you have a cyclist on your Christmas list, this KickStarter project might be worth investing in. The COBI is a handlebar mounted bluetooth device that links to your smartphone, safely stashed in your pocket or saddlebag. It will give directions, weather updates, and much more. Securely mounted, you won't be dropping your phone, or running into stuff anymore. I have a cyclist friend; but, he can buy one for himself.
