digital.bike.23: Eckpfeiler des geplanten Projekts: digital, nachhaltig und human // Fahrzeug: zirkulär nutzbar oder recyclefähig, Connectivity: open source und langfristig updatebar, Finanzierung: gemeinwohlorientiert // Projektkonzeption: J. Tiffe Concept // Grafics: J. Tiffe  CC BY-NC-SA

Dieser Blog ist Teil des Projekts „digital.bike.23“. Das beschäftigt sich mit der spannenden Frage: Ist es möglich mit Hilfe unserer aktuellen Technologien E-Bikes umweltschonend zu entwickeln, zu produzieren und zu entsorgen? Wie sieht ein digitales faires Open Source Fahrzeug aus? Wie wirken sich diese Vorgaben auf sein Design und seine Konnektivität aus? Hier schreibe ich über interessante Rechercheergebnisse und spannende Themen, die mir auf dem Weg begegnen, z.B. Open Source, IoT, 3D-Druck…Mehr…

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.

Eurobike 2012 – Daily Business?

Known and unknown manufacturers presented their announced news. New Companies like Momentum from Great Briten joined the old bulls. A lot of the news is already pubblished in the relevant media, missing themes will follow in the forthcoming days. My question of interest was:Does the market explode in reality? My personal impression is: no, not yet.

Impressions from the fair:

The range of  applications diversifies and technical developments are coming and great visions were shown. More…

Future starts now

The speed of the drive-developments is amazing. On my actual list are ten companies, which present new drive-systems. As far as I know all can be tested at Eurobike. Some of them are revolutionary. Höganäs and MotorExellence will show their transverse flux motors, Protanium will present a kadern-motor and – if true – the most advanced motor will be shown by nexxtdrive, a step-less drive.

            

Specially these projects catched my attention. But they are far away of being all. Winora developed a new motor together with TranzX, Panasonic shows a rear hub motor together with KTM, AEG will present interesting kits and add pressure on Bosch, who also presents a more powerful motor. Kalkhoff cooperated with Alber for a new rear hub motor and Brose will take the next steps with their middle motor. Last but not least: Giant presents new bikes with Yamaha motor. How many others will present new drive concepts at Eurobike 2012? And which products are really reliable?

After my talk at the bike conference in Munich in two days (July, 26th), I´ll post more details…and look forwards to comments and input.
