I bought my 1998 mountain bike off craig's list a couple of years ago. It was top of the line in the day but had suffered significant depreciation with all the advances in bike designs. It had been sitting in the first owners garage for 20 or so years, bought with the best of intentions that were quickly abandoned. Not to comment on anyone here, but some people start off with good intentions with bikes that don't last long and Craig's routinely has what might be called barn finds. The other day I was on a local trail and a guy on an eBike pulled up next to me and said, "you should get one of these", to which I asked, "why?" He said you can go farther and faster. I've always been happy with how far and fast I can go on my old bike, but that's probably the crux of the question.
A friend and experienced cyclist was struck by a car and died, so I'm a little sensitive to the safety issue, but I think cycling is fairly safe for people who are cautious and use common sense. The car always has the right of way. I see a lot of elite type cyclists who ignore common safety sense.
Here we have nice trails and a reasonable attempt at street bike lanes for a network that can connect a lot of shopping places and businesses. They get quite a bit of use but mostly from recreationist rather than commuters. Maybe eBikes have a chance to help that out.
