Anyone got any experience of this type of electric assistance? Looks like it has a lot going for it. Is there only one choice (50/34) of chainset that fits?
No I don't, but if you are looking for some e support for a normal bike, the Austrian Vivax assist system is the way to go. No special downtube or bottom bracket required, can be fitted to most bikes with standard diameter seat tubes.
Sorry, website seems to be in German only,
