Völlig abgedreht: Aerobicle - Propeller-Antrieb für Fahrräder! Fotos und Video

[autopost]

Ideen muss man haben: Das Aerobicle ist der erste Propeller-Antrieb für Fahrräder. Sehen so die E-Bikes der Zukunft aus? Klingt völlig durchgedreht - und sieht auch ein wenig so aus.

Die folgende Diskussion bezieht sich auf den Artikel
Völlig abgedreht: Aerobicle - Propeller-Antrieb für Fahrräder! Fotos und Video bei www.urbanbiking.de

Verrückt, witzig oder ein System mit Zukunft: Was halten Sie vom Aerobicle - dem Propeller-Antrieb für Fahrräder?

Well! Thank you, UrbanBIking.de!
Will answer with pleasure to all questions, as we just started Aerobicles' production so any discussion will only make them better!
The fact is: result is more exciting than you could expect.
Idea is not new (attempt to use propeller on bike made and in 1913), but it is first one, that uses features and advantages of ELECTRIC motor. Also - Aerobicle was designed and calculated by aerospace specialists. Plus this is just PRODUCT, but not concept only. Welcome to discussion! (in English if possible)

You made mistake in article. Possible speed of bike with Aerobicle is MORE than 40 km/h (without pedalling of cause).

Air flow speed after propeller at full power (measured): 98 km/h. Trust: 8 kg
So, you could calculate the speed for your bike with simple formulas from physics or using bike calculator or simple logic: trust of 8 kg is equal to the case, when you're gowing with your bike down the hill of about 10% (80kg (bike+cyclist) x 0,1) (that is very big decline! - 100 m per 1 km of way).

Hi!
Thanks for your answer. We just quoted your website regarding the max-speed:

max* (flat road, no pedals, propeller only) - 40 km/h
(*) - it is not maximal speed, posible to achive with Aerobicle, it is maximal speed in 100 km tests.

I added the information that you could achive an even higher max-speed with the Aerobicle - without pedalling.

How many of your propeller-kits have you already sold?

Best regards

Björn

Dear Björn Gerteis!
Thank you!

We started to make and sell (carbon fiber) kits now.

We will make tests soon (we make preparations...) for maximal speed and will inform then!
Will be video on Youtube also.

And - thank you for your interesting web site for e-bikes.

Sorry but I really think that this idea is only very dangerous. When I see how long the propeller still rotates without pushing the gas. Maybe you have to brake the brushless motor actively or shorten it. What does happen if I have an accident? And a children who touches in there??? I touched a smaller prop with my little finger while it was running. For my luck there didn't happen very much but I know what could happen.

I think you really have to invent something like a safety system which reacts fast enough to prevent such things.

With kind regards from Germany

Also, ich finde das in der Tat ziemlich abgedreht und musste erst einmal auf's Datum schauen - nein, es ist nicht der 1. April der Tag der Veröffentlichung.

Und in der Tat - das Ganze wirkt doch sehr gefährlich. Sicher könnte man den Propeller auf eine WEise verkleiden, die es für andere Verkehrsteilnehmer sicherer macht, aber dann taucht natürlich das Problem des Gewichtes auf ...
