Rollerblading

While "advanced" wizard frames are not the best for urban use, the "normal" ones (ie; the ones with a small, non-progressive rocker) are perfect for it - they offer more agility and reaction speed than a flat setup, while being just as stable due to the length of the frame, with the only trade-offs being requiring more energy -as any rockered setup-, and being less safe when turning at high speeds (50km/h+), which isn't a problem unless you live in a city in Switzerland or similar.

I live in a city where there's a pothole every corner and poor pavement is the norm, and I can say that the Endless are much better than standard flat frames; not only does the rocker help prevent getting caught on imperfections, but the longer frame also gives you more stability.
