To increase commuting by bike, I'd suggest to move businesses to where the cycling infrastructure already exists vs moving cycling infrastructure to the already very dense business areas. These areas should then be further developed for mixed use development. As it currently stands, many people commute far distances to urban areas. Good biking infrastructure will not convince those people to switch to bikes. People in urban areas may benefit, but then again, the additional infrastructure for safe biking and bicycle storage would just further exacerbate foot and road congestion.
