Thanks for the link though, some good info there.
From what i've read in forums and reviews, the velogicals are pretty reliable (unless very icy...). conventional sidewall dynos just destroy the tire, if you press them to hard to the tire. The velogical can press much stronger against the rim without damaging anything.
Just send an email to them, if you like the concept, to inquire whether it'd work with your rim. The guys are pretty helpful (i once inquired about their e-bike-motors)

Depending on the harvester model, you can get a lot more power from the dyno, even at reasonable 20 km/h:

In that overview, they also mention the Axa Luxx 70 Plus as a light with USB port, and it even has a switch to select whether you want light or charging.
