Advanced Bicycle Mechanics Classes

At Freewheelin’, apron colors are used in the same way as in karate belts: to mark a student’s level of mastery. Each apron color (Green, Red, Purple and Black Apron) indicates a specific level of mastery over particular skills and principles. Kids build their confidence with each new apron and can mentor other youths to build their skills.

Green Apron – This is a pre-requisite for the advanced mechanics classes below.  Click here for more information about the Green Apron/Earn-A-Bike class.

Red Apron – Introduces Science/Technology/Engineering/Math (STEM) and Social Emotional Learning (SEL) concepts.
STEM aspects include:
    • Fine adjustment
    • Precision vs. accuracy
    • Chain pitch and measuring wear
    • Friction
    • Tension
    • Compression
SEL aspects include:
    • Asking open-ended questions
    • Mirroring and active listening
    • Emotional Labor
    • The reflexive relationship between physiology, emotions, and mechanical work
Purple Apron – Provides the opportunity to level-up mechanical skills with the introduction of adjustments to all major bearing systems, wheel truing, and a deep dive into gearing.  Additional SEL aspects are also introduced.
STEM concepts added:
    • Mechanical stress
    • Leverage
    • Ratios
    • Torsion
SEL concepts added:
    • Interpersonal communication
    • Reflective and reflexive practices
    • Stress and its impact on the body and relationships
The Purple Apron includes an opportunity to practice assembling a bike new from the box, which is a valuable skill when seeking entry level employment with bike shops.

Black Apron – Focuses on the overhaul of all major systems of the bike, and includes disassembling, cleaning, and reassembling a bike and replacing parts. This capstone course requires students to meet high standards, with an eye toward mastering competencies required by employers.
SEL concepts added:
    • Showing respect
    • Kindness
    • Empathy
At the Black Apron level, learners are able to identify their individual interests to ensure they they will stay engaged in a lifetime of learning.
