BigAura, please think twice before you start telling folks to be ashamed.
I'm not sure what you think you mean by "real bicycle people", so here are some of my bona fides: Started riding in 2010, worked my way up from sucking wind with an 8 mile flat commute to doing a 400 mile bike tour this time last summer. If you look over in the Clydesdale & Athena section -- since it seems like you only care about riding for fitness and weight loss -- you'll find tour reports.

A few months ago, Something Bad happened to my knees. I'm not sure what yet, despite visits to multiple specialists, Xrays, MRI, needles getting fluid out, and needles putting medicine in. Right now, if I want to ride, I need to start on a bike that's already rolling -- I don't have the strength to generate the torque to get the bike moving from a standstill, but I can keep it moving once it gets rolling. That means that if I want to ride at all, I need an ebike.

So -- should I sit home and do nothing, or do what I can? Is my reason good enough? Do I meet your standards?

Which leads to the next question, of course: why do you care why other people ride? Maybe you see someone who is new at this whole idea, who likes the security of being able to handle hills. Maybe someone can't do 6 miles yet, but wants to find some goddam way to get moving, somehow, at all. Maybe you're running into someone who wants to be able to carry groceries home. Or maybe, just maybe, you're seeing someone who just wants an ebike.
