Free Women’s Night
A safe space to learn basic bike repair at your own pace, our programs emphasize inclusion, access, and community. Instruction includes basic skill development in common roadside repairs and mechanical safety. Bring your own bike or learn on one of ours.
Next up: September 16th, 6:00 – 8:00 pm

Meet our new Affinity Programs Manager, Isabel Chavez (she/her/her/ella). Isabel became involved with Good Karma Bikes early in 2022 through our partnership with Silicon Valley Rainbow Rotary and soon became a regular participant in our affinity night programs. She has been a wonderful and loyal volunteer, and we are happy to announce she has joined our staff! Isabel is a charter member and the secretary of the Silicon Valley Rainbow Rotary. Currently, she is studying at San Jose City College with an undeclared major but hopes to find her true passion soon. When she is not studying and finishing homework assignments, she can be found in the woods enjoying nature, learning Italian, or enjoying a theater show around town.
