Re: Building my own dream elektrical bike!

1 motor that will bring me up to a speed of 65+km/h. If you want to sit upright you need at least 2000W mechanical power at the wheel to achieve that (around 2500W electric power). http://www.kreuzotter.de/english/espeed.htm If you want to survive in the long end you need a different frame. Also th...

Re: If you could reset the speed/power limit what would it b

Have you got a link to the official requirements for s-Pedelecs? I am interested to read the actual wording. such a document does not exist. If you understand German this would be a start: http://www.pedelecforum.de/wiki/doku.php?id=rechtliches:start (2.3. ff) in English I recommend this one, but i...

You would be against the changes proposed by ETRA? The 250W max. only exist on paper, because there is no legal definition of continou...

Personally I don't see a need for any limit at all. As long as it has functional pedals on it, it's a bicycle. ;) . I do agree with the first part. No limits are needed. you can have 100kW power and 250km/h top speed. That's called a motor cycle and you must have insurance, drivers licence and so o...

Re: If you could reset the speed/power limit what would it b

I think that the rules in Germany (some other EU countries) are quite ok. We have 1.) Pedelecs: 25km/h motor limit and 250W continuous power limit. In reality Pedelcs with BionX or Bosch motors consume 20-30A at 36V for short times and are legal, so peak power is much higher than 250W. Also the typi...
