Take apart bikes and salvage some components for reuse
Assess, clean, and fix up bikes
Organize the shop and help with cleaning tasks
Help plan and prepare for upcoming events
Special opportunities like delivering bikes to our partners or helping community outreach
Learn about bikes and Chain Reaction while enjoying good company
No experience or RSVP is necessary!

Volunteer Workshop: Hands-Off Wrenching (Public Bench)
Calling all volunteers! One of Chain Reaction’s big 2026 goals is growing our ‘public bench’ space, where anyone can come work on their bike with the guidance of a volunteer mechanic. Instead of fixing someone’s bike with our own hands, we fix with verbal instruction.
Following in the footsteps of several other community bike shops, and like our favorite Iowa City Bike Library (ICBL), we’ll be launching “Hands Off Wrenching.” This is a big skill to learn - not just fixing, but teaching with an empathetic, hands off approach.
Drew Boss, ICBL’s lead mechanic, will join us for this workshop to talk about the basics of hands-off mechanics, some of ICBL’s lessons learned, and help our volunteers get a first hand view of how to volunteer at our upcoming public bench launch.
🛠️ What we’ll cover:
✅ Overview of hands-off wrenching
✅ Tips and techniques to teach verbally
✅ Lessons learned from ICBL
✅ Q&A
This is open to current volunteers. You do not have to be a bike expert to volunteer - just interested in helping folks and have attended a previous orientation. Thanks for your interest in growing CRBH’s community impact!

Community Workshop: Bike Hygiene
It’s the season of mud & muck - let’s learn how to take care of our bikes and keep them running in good shape.
Join us for a hands-on, community-powered workshop where we’ll demystify the basics of keeping your bike cleaned up and riding smooth! Whether you’re a new rider or just want to feel more confident on two wheels, this is the perfect chance to learn and connect.
🛠️ What we’ll cover:
✅ Cleaning and lubrication of chain and drive train, including how to remove wheels for access
✅ Identifying common wear and tear, and what to do about it
✅ What products to use (or not use) to keep your bike riding smoothly
✅ FAQs
We highly encourage you to bring your own bike so you’re able to learn the techniques and tips on your personal rig. We’ve got plenty of bikes to practice on in case you need to borrow one.
