For the first time since she was a kid, JJ Sheffer owns a bike.

But the 35-year-old mother is a little nervous about venturing out on long rides with her 14-year-old son.

"I don't know what I would do if I got a flat," Sheffer said. "I don't know how to fix it yet."

That's likely to change Saturday, Aug. 16 — when Sheffer and other cycling amateurs will gather in a downtown York City office to learn the basics of roadside bike repair and maintenance.

Afterward, the instructor and his students will take a short bike ride on the York County Heritage Rail Trail.

The class is one of 16 "skill swap" workshops scheduled for August at CoWork155, a membership-based workspace for entrepreneurs, telecommuters, freelancers, sales executives and others who work remotely.

CoWork155 opened a year ago at 155 W. Market St.

How it works: SkillSwap is a barter-based education program that invites presenters to share useful information and knowledge with interested participants.

In exchange, the students bring goodies like fresh-baked cookies or six-packs of beer. They can offer instructors help with building a website or weeding a garden, for example.

There's no money involved.

Sheffer said she first heard of the SkillSwap idea through a Kickstarter campaign.

The concept seemed to mesh with CoWork155's atmosphere of community, collaboration, creativity and sharing, she said.


The first series kicked off in June. Upcoming classes include "Homemade Snacks Made Easy," "Basic Juggling," "How to Pick and Eat a Maryland Blue Crab," "Couponing 101" and "Introduction to Homebrewing."
