Without Thomas Edison there would probably no e-bikes . Since it seems appropriate, the current pioneer a Wheel devote. Namely, one that can be the presence of the future of the bicycle, because Hercules presents the Edison Di2 the e-bike to the square: So not only Shimano brand new Steps mid-engine supports the pedal force.

The gears on the wheel by using electronics. The switching commands are not by cable operated from the handlebar to the IGH received, but in my current signal to a small motor. Advantage: a faster and more precise shifting. The second major innovation is the Shimano engine. In its first real test in the electric bike he immediately convinced with direct response, refined running characteristics and attractive power.

Even the tidy display and tactile controller like. Just a bit quieter likely the engine go to work. Compared to the test winners Kettler Traveller E-Light the Edison weaker values in supporting tour and city.
