The Electra Townie 7 is an excellent bike for its purpose. A long wheel-base and low centre of gravity makes it a very steady and stable ride. The seating position and forward orientated pedals mean most people are easily able to put their feet squarely on the ground. If you are especially petite there is a 24" wheel version. The aluminium frame, whilst no feather, is quite light compared to other steel-framed cruiser-type bikes.
It is excellent for cruising around the shore or your local retirement community, but if you have any further ambition; ie. riding up hills, cycling more than 5 miles, using it than anything other than a convalescent exercise device, then you really need to look at another genre of bike.
The lbs where I help out sells loads, and my wife has one which she loves. They are pretty much the best of what they are. But if you're looking for a machine which will reward exercise and expand horizons, then look for a different type of bicycle.
