this is funny... a key holder that gives you a choice... ride the bike, or if you choose the car keys it will dump your bike key on the floor for you to pick up, as you obviously need the ab workout

If you usually drive, you’ll probably drive, even if you want a little extra exercise or a lower carbon footprint. But a new design tries to change that habit by inserting a tiny bit of annoyance in your everyday routine.

The Keymoment is a key rack that holds your bike key and car key at opposite ends. If you choose the car key, the bike key will automatically drop to the ground, forcing you to pick it up and hold both keys in your hands. Suddenly you’re considering the bike ride one more time.
