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. Besides, we applaud anything that obviates the need for those nerdsome helmet mirrors.
