If you look up the Urban Design Compendium it'll have some info. But i've had the same issue on a masterplan i've been working on in the Thames Gateway. What i did was consider the average speed of a little old lady cycling and drew cycling-bands per time - 10 minute cycle, 5 minute cycle etc. If you want to do it properly though you'd have to change the average speed in accordance to the topography and the gardient.
Whatever you do, remember - cycling lanes are mostly bad as they breed vehicular ownership over the road (except for major strategic links where they are good)
