I LCF out of necessity in a small mountain town. Its possible to haul groceries home on a bike as well as for fitness. For heavy loads impractical to transport by bike, I have such goods shipped to my door via UPS/Fed-ex.
Not having a car makes rural life easier. You eventually learn to live not with what you think you need but with what you must do without.
The bike simplifies lifestyle and you live your life around it.
