Connected Mobility: Von Sharing zu MaaS

Vernetzung kann einfach großartig sein. Nachdem er meinen E-Scooter-Post gelesen hatte, schickte mir ein Freund einen Artikel aus der Fortune. Der diskutierte den ökonomischen Megaflop des Dockless Bike-Sharing in China. Und die Frage, ob Investoren für ihre Investments haften sollten, damit sie Verantwortung lernen. Großartige Idee!

Die meisten chinesischen Firmen sind von der Bildfläche verschwunden – insolvent. Nur Mobike konnte sich anscheinend vor dem Totalcrash retten. Es wurde übernommen; seinen gesammelten Daten sei Dank. Die Sache mit den Daten haben die E-Scooter-Flottenbetreiber verstanden. Aber wie sieht es mit dem Rest aus?
 Anyway: Der Artikel ist ein prima Übergang zum nächsten Thema: Das Teilen und Herrschen in der Connected Mobility im Alltag des Modal Splits. Los geht`s: More…

Bauhaus Dessau – Brauhaus oder Krise als Chance?

Das Bauhaus Dessau sagt das Konzert von Feine Sahne Fischfilet ab. Was nun folgt, ist beeindruckend:

Das alles macht Hoffnung und daher ließe sich sagen: Ende gut, alles gut. Aber so ist es nicht. More…

Integrative Drive Systems – A Comment to a Mail

It is great to get comments on my posts. Lately I got one via mail, which was very interesting, since it concerned one of the most intrigering drive systems: the NexxtDrive drive. I got a link to the Zemo-project from ZEG (pdf / language: german). Already in 2008 ZEG thought about checking out the NexxtDrive system. In the end they decided against it in favour for the Bosch system. The decision was based on a study, which claimed that the NexxtDrive system will never work properly. During my latest research I checked out a patent from F. Moeller for NexxtDrive from 2010 . The resulting drive system seems to be a very comfortable drive which integrates electric and muscle power – perfect for citybikes. It provides a variable transmission ratio and electric braking.


In the Go Pedelec Reader H. Neupert talked about upcoming drive systems. Like him I´m convinced one future option for the drives is to integrate muscle and electric power. The pedelec from Dolphin E-Bikes is still one of the best bikes on the market concerning performance. It reacts direct and powerful. Why? It works with a drive system which integrates both kind of power.

Back to the Future? Highlights and Findings from 30 years Pedelec History

While digging deep in history of electric bicycles I brought up fascinating facts. The research gave me a more intimate understanding of how long technical developments need and under which conditions they get ready for a  market. I realized that they even need longer to be accepted and bought by customers. A good general overview over the history of electric bicycles is already written by Hannes Neupert in ExtraEnergy Magazin 03. My aim is here to line out some highlights, which attracted my attention.

Beside all I made two interesting findings:
1. many technical developments, which are on the way to enter or just implemented into todays market,  were invented in the middle of the 90s or ealier.
2. some of these inventions are not yet integrated in the markets. They show a way in which the journey will go previously. More…

Drive Developments

Another fascinating field are the drive developments. A variety of motor prototypes elated the prime enthusiasts but they disappeared in a garage before even reaching the pre-series. In Germany Heinzmann was quite successful with motors developed specially for pedelecs. Other companies bought motors for the series in Asia or / and used them for purposes other than intended. An example is Hercules, who used a long time a wipermotor for the “Electra Classic“. Beside the state-of-the-art solutions I found projects, which where ahead of its times.


These are the ones I´ll introduce here since they are of interest for my project „e-bikeP23“. More…
