The Knoxville Regional Bicycle Program has a free 1-hr class on safely riding one's bicycle on city streets. The class consists of a 5 min talk followed by a slow ride around town. An upcoming session is on Thursday September 27, at 6:30 PM starting at Market Square downtown. A bike and helmet are required. Signups are at the following link.
For beginning riders, taking a class such as this one can go quite a ways toward building riding confidence, as well as avoiding common beginner mistakes. The League of American Bicyclists has their own training courses. What other similar courses exist around the state?
