Choice did not tell me much at all.
Have looked through Woolys Wheels.
Have looked through Clarence Street Cyclery.
Have looked through Inner City Cycles.
Clarence Street is for people who are loaded or bike-snobs. Woolys stocks Giant brand, too, but at about $200 more than Glebe.
Inner City Cycles have a rudimentary web site, but the bikes are within my range and my level of detail. They also have a bike group that meets early each Saturday.
Not sure that my travelling partner sees the need to get tough by cycling. She wants just to do more strenuous walking. I think both will be essential. More as today progresses.
