You can guess the purpose of the rear view camera on your car, and that is so you don’t have to turn your head to reverse (therefore making you even lazier then before) plus other safety options (like not backing over your kid). What is the purpose of it on a bike? No, not a road bike, but a simple peddle bike!
Cerevellum have created a rear view camera for your peddle bike, which displays what is going on behind you on its 3.5 inch screen. The system also features a 4 hour battery life, 32 mb of storage for workout data, and 4 USB ports for expanding the device with modules (GPS maybe?). The cost of this handle bar mounted device will be around $US200, but is still currently a concept.
If you have ever ridden a bike on the open road, you will know how dangerous it can be so this could be a logical solution. When you are travelling at higher speeds, turning your head to check around you could be dangerous, but is it enough to rely on a electronic device? What do you guys think?
