This article points out how to create a custom travel mode for jogging time - vs walking time (by adjusting the walking speed from 5km/hr) by simply duplicating the walking time travel mode.

But there is no travel mode option for Cycling Time - which I think is a real shortcoming. However I cannot simply duplicate the Driving Time mode - as it shows me 0 TravelTime parameter.
What paramaters should I set to create a custom travel mode for cycling?
