There isn't a good way to create a cycling travel mode. Cycling require a different travel time and a different set of restrictions (some of the roads are not suitable for cycling), we don't have those information in our data so we don't have a cost attribute for cycling time or a restriction attribute for cycling, so you couldn't really create a cycling travel mode from existing travel mode.
Create Jogging travel mode from Walking travel mode is simpler, because all the restrictions are the same, you can simply just change the speeds.
