When was the last time you spent some time on a mountain bike? Has it really been that long that you can no longer remember it? Well, for those who do remember, mountain bikes come with a gear system – and you will need to toggle the front and back wheel gears with your thumbs. However, since we are living in a high tech digital age these days, don’t you think that it makes much more sense to have the entire gear shift system digitized? This is what Shimano did with their Alfine Di2 road bike that sports Shimano’s very own advanced electronic shifting system. Originally designed for the high-end Dura-Ace bicycles, this particular system will require tiny electrical charges to keep it going, delivering fast, smooth, and accurate gear changes to boot.

There is an LED display that will be fitted to the handle in a discreet manner, showing off the current gear speed alongside battery life. A single lithium ion battery charge will enable your bicycle to travel for over 1,000 miles, which is plenty of distance to cover even if you are one of the more hardcore cyclists around. Not only that, the Alfine Di2 shrugs off tough weather conditions as the internal hub drive train remains sealed, minimizing exposure in the process.
