I think these things can help (in no order):
1. Encouragement/support for businesses to provide lockers, showers and and a secure place to lock up the bike.
2. Bike on bus options (either on front racks or in bus)
3. Improvements to road surface
4. Increasing width of outside lane where existing road has a very narrow no shoulder outside lane
5. City support for 'bike tours' and bike awareness
6. Reduction of and enforcement of speed limits so urban/suburban roads are kept below 40-45mph.
