Very nice: on-the-go cycling directions (though US only for now):

Since launching biking directions on desktop Google Maps, we’ve wanted to get you biking directions, lanes, and trails on your phone too. Just in time for National Bike Month, select the bike icon when getting directions to get an optimal bicycling route in the U.S. If you’re in the mood for a more scenic ride, you’ll also see the Bicycling layer on the map which shows dedicated bike-only trails (dark green), roads with bike lanes (light green), or roads that are good for biking but lack a dedicated lane (dashed green).
