What do we do?

Come visit us and we will do our best to give you free advice on whatever ails your bike and if possible, show you how to fix it. We don’t keep a large inventory of many parts (e.g. we have some brake pads but not chains), but usually can help you with basic adjustments and repairs.  For other repairs, we can tell you what you need, and if you bring us the new parts we can show you how to install them. We are glad to receive cash donations for the purchase of  tools and "consumables" such as oil, tubes, and patch kits.


We hope to see you – bring your bike and let's work on it together!

Who are we?

We are a handful of volunteers who love bikes and the people who ride them. In 2015, we appeared monthly under a shady tree at the Waltham Farmers’ Market, assisting passersby with everything from diagnosing shifting issues to changing grips. In 2016, thanks to the generous folks at the Charles River Museum of Industry & Innovation and the 128 Business Council, we’re now located at the Museum and are able to set up shop indoors or out, depending on the weather. We’re also grateful to The Jones Partnership Fund of First Parish in Waltham for financial support that allowed us to purchase bicycle tools and stands in 2016.

Why do we do this?

"Why do you do this? There must be a catch" is one of the comments we often receive at the Bike Lab. It's simple. We want to see more people riding bikes. It's no fun to ride a bike that's giving you trouble, and it's empowering and fun for everyone to learn some basic maintenance.
