Bike compartments were going to be available in the new ICE4 trains from the end of 2017. Only eight bike slots per train, though, which is not nearly enough, and inflexible given that there are seasonally varying levels of demand.
As the article says, there are many more bike bookings in the summer months and far fewer in the winter, so there'll be some proper competition and spontaneous booking will basically be impossible when it gets busy.
Just looked it up again:
