Thanks euphonius, yes, the temperature and hills here make cycling a challenge. The Miami comparison is a good one but I don't know about the topography of San Francisco except for what I've seen in movies.

I've been pleasantly surprised at the number of threads on e-bikes and the range that are on the market. For example the bike in Felixs' review, which along with his panda is very good looking . I wonder if we aren't getting to a point where a separate forum on e.bikes would be justified, unless one exists that I haven't seen. There were two other good looking 72v e-bikes available when I bought mine and it was a hard choice. The headlight did it for me. I'll post a picture of those two a bit later.
