In austria the law is quite strict and only allows up to 600w peak/250w continous motor power and max 25 kph speed.

It is 3kw motor .... would run near 80kmh
We are still talking about a mountain bike to be used in Europe in a densely populated city in rush hour traffic?!
:shock: I hope you are well insured... :wink:

Indeed, strong frames are preferred for such powers and weight.
Strictly policed regions requires ebike to be less noticeable. I assume that is the reason using mountain frame.
Controller can be set to have few hundred watts.
Setup has potential to be run at power above or within legal limit. Rider can adjust power according location. In city set it to few hundred watts, offroad increase power. With button it is done on the fly.

In the Kunteng-controller-open-source-firmware project I have implemented a "morse code" with the brake lever to disable the speed limit :D

This helps nothing, it will be illegal in Europe anyway.
We just had a long discussion in the german forum, as the police has stopped a rider with a VanMoof Ebike, that can be switched from EU-mode (25kph) to US-mode (32kph) via a smartphone app...
The VanMoof is very stealthy :wink:

sounds good.

Experimental vehicle owners exempt themselves from rules, otherwise not good to go.

In vienna the traffic is really like a relaxed weekend trip compared to other cities this size :wink:
Also vienna has one of the greatest cycle path networks in the whole world, so its not really like being part of car traffic. Nevertheless you are right, and you should always evaluate the risk and be informed about the law. And AS LONG as nothing happens and AS LONG as you drive reasonable it seems possible to use my bike...with a secret speed switch :lol:

You assume totally right :wink:
For now i have a good mtb but it has no rear suspension and the dropout might be to weak for the torque.. even with torque arm.
Thats why i'm looking for a stable dhb.
i already installed a hidden 3 speed switch and with the new controller i can modify how much power speed 1,2, and 3 has 8)
