and you can still see it: the first Generation of electric drives of Bosch, which stuck like a brick under the bottom bracket of the Bicycle. Since their Emergence a decade has passed. The Reutlingen-based market leader as is the case with the competitors, the motors Nestle today-as well as the batteries always compact and always pleasing to the lines of the bike frame. They have become smaller, but also narrower. And the newly emerging on the market systems do not make the detour through the bulk of the original.
The prevailing mid-engines are no longer looking like the beginning in a at all brands and models pretty much the same, because the engine manufacturer developed arc screwed-shaped receptacle. Which worked, as you have cut the bottom bracket from the frame to a standard carrier to add welding with the screw holes. Such points of attachment needs, of course, the latest Generation of engines. But the manufacturer of the wheels are now more frequent than in previous years, you can’t hang the motors only horizontally at the bottom in the frame.
It just looks fancier, if you installed an angled the Motor a little. Then he continues quite harmoniously the often-edged and strong-sized tube in the top of the battery is to be placed. You can leave the drive in a Bicycle brand typical cover disappear, even if the same engine as the competitors is stuck underneath. Last but not least, and this individualization is forms, the development of its own framework, a cost issue: The continued demand for electric bikes has made the developments financially feasible, integrate the electric drive and more than one bike, just bolt-on extension appear.
concept aims at two different groups of interested parties
More bikes to choose from, which combine a smaller engine of the same power with a smaller battery, but due to lower capacity, less range. The is also a result of the theme of the range plays the Pedelec the dominant role. But above all, the concept is aimed at two different groups of interested parties. For a very chic and light city can wheels build. Pioneer Coboc in Heidelberg was this: On the simple elegance and light weight was placed in the development of more value than the greatest possible range for a long Bicycle tour. After all, the 350 watt-hours that you can have in Coboc, enough for 75 to 100 kilometers on the paper all enough for the city.
Coboc used with a self-developed control a Motor of the Chinese manufacturer Bafang in the rear hub, which was hardly larger than a switching hub. The battery was installed in the down tube of the frame, a button and a few LEDs had to meet in order to regulate support and to inform about the charging status of the battery of coarse. No Display and no cable between the Handlebar and the auxiliary drive disturbed the very clean image. Who wants to have instead of this minimalism more information, or Navigation, can now be Coboc with an App on his Smartphone on the Handlebars. Then, the characteristics of the actuator can be configured.
