Exercise bikes can be a little boring. Even with some music or mindless TV in the background, it's a mind-numbing workout. Pedalling, pedalling, pedalling. Not for Aaron Puzey. The Brit has developed an app for Samsung's Gear VR headset which displays Street View imagery while he's riding. Using a Bluetooth cadence sensor, which tracks how fast he's pedalling, the app knows when to manipulate and change the panoramas, giving the impression that he's travelling. His goal? To ride the length of Britain, from Land's End in Cornwall to John O'Groats in Scotland.
