I ordered a www.grubberassist.com, I guess based on the knowledge of John TETZ;
rather expensive (2000 euros), but 100watt real assist, the whole system weight
is 1.9 kilo, needing a bycicle wth a special frame-tube diameter;

Hello Paul;
Sorry I have been away from this ULEA site.

I tried contacting Gruber to find out how they claim 1 hour or more run times on
such a small Li battery. Theysent me a URL showing a chart of run times. But the
chart was a bit confusing to decifer.

I like the Gruber concept. Light weight,low power. And reasonably compatable
with up right bikes.
