Personally, I like to go a bit faster than brisk walking speed which is what the StVZO/TA regulations seem to be limiting cyclist to. I don't usually side with the anti-regulation crowd but a little bit of Wild Westness is sometimes good for innovation.
The Magic Shines and their clones aren't junk, by the way. I've owned several and they all work extremely well...especially considering the cost. Lots of value for the money.
