Pass the Bike Test (and be a great rider too!): Your Real-World Survival Guide to a Great First Year in Biking by Sean Hayes
This book teaches new riders how to become confident and safe on the road. It's the first book which arms beginners with the knowledge to choose an excellent bike training school, to monitor their own training, and to start riding with a full complement of real-world survival skills. It also covers post-test improvement, the causes of the most common accidents (written by a police accident investigator), and advice on getting back into biking.
Whether you are about to do your CBT, have trained on a direct access course, learned over the course of a few months - or if it has been a long time since you have regularly ridden a motorcyle, this book will guide through the techniques and knowledge you need to be a safe and confident rider.
