I'm 68 and have no trouble mounting or dismounting a regular road bike. However, some time ago I injured myself to the point where I couldn't just swing my leg over. The solution was simple....to mount, just lay the bike down on the ground, step over it, and lift the bike up beneath me so that I was straddling the top tube. Dismount is the reverse of mounting. If following this procedure I don't see how there could be a problem...am I wrong about this?
