Since the second part of this thread is labled safety, I thot I would post the following for comment.

In 1890 give or take the "safety" bike was invented. It is what we have called the diamond frame bike for more than 100 years. It was called safety because it got rid of the huge wheel of the penney farthling.

Now consider that the LWB recumbent is the true safety bike. You cant be thrown over the handlebars. There is a short distance to fall in the case of a wreck. Your feet arrive at the scene of the accident first, not your head. The weight shift forward without pitching over the handlebars allows for better braking. And sitting upright with 180 degrees view allows you to stay out of trouble.
