  1. SD Standard deviation
  2. aDutch physical activity norms:
  3. - DNHPA Dutch Norm for Health-enhancing Physical Activity: Thirty minutes or more of at least moderate-intensity aerobic (endurance) physical activity on at least five days each week
  4. - Fit-norm: Twenty minutes or more of vigorous-intensity physical activity on at least three days each week
  5. - Combi-norm: Meeting the DNHPA and/or Fit-norm
  6. b P-value for change in physical activity within the Start2Bike group
  7. c P-value for change in physical activity within the control group
  8. *Significant (p < 0.05) change in physical activity after six months within the Start2Bike group
