The one exception to the rule about Deltas being easier to get in and out of than a tadpole is probably the Terra Trike Rover that I got for my wife. Just before her 65th birthday she showed interest in a trike, and we got her a very lightly used Rover with an internally geared 8 speed hub. It is a little bit heavy, but a VERY NICE trike for an older person to start out on, and sits high enough for her to get in and out without too much effort. She really loves that trike and rides it several times a week around the neighborhood. We had a nice discussion last night about 'spinning' and how fast she should be cranking the bike...
