(1- Hardest, 5- Easyest )
4 - Daily Commute (to work, school, etc.)
2.5 - Shopping (because you have to carry groceries all the way back home.)
3.5 - Personal or Family Business (Depends how far it is.)
3.8 - Social & Recreational (Again, it depends)
I think for me biking to school is easy, well I have one big hill I have to run up but other than that Its pretty easy.
