77 years old, you want to check that the sense of balance is Ok, if not, get a 3 speed, coaster brake trike.
Walmart bikes are generally made with really cruddy components (in spite of the brand name) and are generally assembled by unmotivated staff.
I think of Sun as entry level decent Cruisers. I own a Sun Retro-7 (7speed). 1500+ miles in the first 6 months of 2013.
I think in general a 3 piece crank is good indicator of a quality Cruiser (but some walmart "Next" bikes have them too).
There are some woman's 3G cruisers with pink accents.
The Electra Cruisers are very nice. Aluminum frame, 3 piece crank, pedal forward design. I am looking at a 7 speed for myself.
If she's on the small side, you might want to go with one of the bikes like your Phat Daisy or these
four Electras with 24" tires.
