Yer, those prices are around average including bike hire.
You will probably have to turn up around 9:00, spend 2 hours or something in the classroom learning theory and the advantages of different types of clothing, security gear etc.
Then you will spend a while out on a private car park or strip of tarmac somewhere getting to grips with the bike. Once you are competant enough in performing the basics, starting, stopping, turning, pulling away etc.
Then you will go out on the road with your instructor and ride around for about 2 hours, until he is again convinced that you are riding safely.
Then you have completed your CBT and can ride a learner legal bike with L plates and work towards your theory and practical tests.
The CBT isnt a formal test its a course, you shouldnt fail it, even if you do, the staff will probably invite you back for a second day at a much lower rate if not for free.
