2. Apple Smart Bike Concept

Definitely a departure from Apple's usual range of products. Is the Apple Smart Bike the company's first eco-focused product?

Able to record your heart rate, speed, distance and even altitude the Smart Bike can then communicate with other Smart Bikes - relaying group information - presumably so you can slow down if someone's finding things a bit tough. we're not sure we'd go as far as to say that this will ever see the light of day, but considering Apple's partnership with Nike, something similar could well be in the works.
