I think either one will be fine for the 2 rides you try it out on. Then you can push it into the corner of the garage when you get an appropriate bike with 26" or 700c wheels.

But on second thought, consider SE's big bmx cruisers , they have a 26" OM and a 29" Big Ripper that would be much better for this type of use

Fairdale Taj is a neat bike at a low price - Fairdale is based out of Austin as well
