Bicycle Mechanics and Repair Decal-

Physics 98/198Spring2014

Presented by BicyCAL, UC Berkeley’s bicycle and Razor scooter repair

cooperative.

BicyCAL is a student founded and cooperatively run organization at UC Berkeley whose mission is to empower UCB students, faculty and staff to successfully integrate the bicycle into their daily lives. To that end we seek to provide a space where members of our community can learn how to maintain, operate and love their bicycles in an inclusive and safe place. We offer peer-to-peer bicycle repair and maintenance education in a radically positive environment.

Learning ObjectivesSafety

• Helmet use• Theft Prevention• Riding at night• Defensive Riding• Preventative Maintenance

Bike Mechanics• Basic repair on the road• Regular upkeep• Advanced diagnosing and

repair on all components of a bicycle

Outreach• Learn and teach others• Explore ways to help the

cycling community at Cal and in the Bay Area

About the Class

• 2 hr. lecture per week– Students will learn the theory behind the basics of

bicycle repair and get hands on experience on all components.

• 1 hr. of field study every other week.– Students will practice and improve their repair

skills with field study, by volunteering in during BicyCal open hours.

Bicycle Safety – Preventative Maintenance

Maybe check your bike once in awhile before your hit the road. This includes:-- Occasionally grab your brakes, make sure they don’t feel overly ‘spongy’ and that they cannot touch your handlebars.– Lubricate the chain once a month or so, more if it is really

rainy or if you leave your bike outside a lot.– Occasionally check the position of your quick-release

skewers (if you have them), especially if you park your bike in crowded bike racks where they can get kicked.

– Pinch your tires and inflate them if they are really squishy.

HelmetsSome people wear helmets all of the time. Some don’t. If you’re going to wear one you may as well get a good one and wear it right.
