It never used to be a problem for me. I always did the running start - step on the pedal, get in motion, swing leg over, and swing leg over while still moving and jumping down, but my fucked up ankle put a stop to that, and two years of not doing any activity where I need to stretch and swing a leg over have left me struggling.
I've kind of worked out where on my street (which is cambered strongly) I can get off and where not (ooops, but at least that time, I didn't fall).

I love my bike. I absolutely adore it, because it is exactly the right height and shape for me, and most stepthrough bikes are too small, which may make mounting easier, and cycling much harder. If needs be, I'll have to get another bike, but I don't wanna, so right now, I've been pushing my bike to the local park and going round and round and pushing it back, because the main roads are vicious at the best of times, and this is not a good time.
