They will have an idea from certain revs in a certain gear, and during practice they can work this out by doing a ride through and watch the LED speed indicators in pit lane which show their speed.

The boards are also on during the race so you can see your speed as you approach the start of pit lane and also see your speed as you leave, the only problem is if a bunch of riders arrive or leave together it's impossible to know who's speed is being shown.
