Bike's rear-view mirror checks your heart rate

If Cerevellum sounds like some Latin term from a medical dictionary, it would be entirely appropriate because it's the name of a new heart-monitoring device. But this one isn't attached to your arm or chest--in fact, it's not affixed to the body at all. Try the handlebars on a bike instead.

The Cerevellum doesn't stop there either: While checking your ticker, this gadget also serves as a GPS system and a digital rear-view display similar to those seen increasingly in cars. According to ProductDose, this all-in-one device has a 3.5-inch screen and 32MB of space to store your fitness data, as well as a 4-hour battery for those who ride that long (unlike us).

All this doesn't come cheap at $299, but we suppose there's some consolidation savings because you won't have to buy three or four separate products for these various functions.
