Bike Mechanics Course Curriculum

The following curriculum is intended to be used for the BWIRC Bike Mechanic Course taught by BWIRC volunteers for students from the Youth Guidance Mentoring Academy.  The Bike Mechanic Course is designed to provide participants with extensive training in bike repair and maintenance. The course is divided into modules.  To successfully complete the course, each student must demonstrate all of the skills listed for each course module.  The course is designed so that each student can complete each module at his or her own pace.  There is no set time for completion of the course.  However, each student is expected to attend class every week (other than excused absences) until he or she completes the course.

Each course module contains a series of videos.  The student are required to watch all videos for each module prior to beginning the in class work on that module.  It is recommend that the students stay one module ahead of wherever they are in class.
