The Laurel Cyclery is open for pick up of completed repairs and online purchases of bikes, accessory and parts. Curbside walk-up service for in-stock items is also available.

Please note that due to high demand, there's a 10-14 day turnaround on assembly of bicycle purchases. We will reach out to folks to schedule bike pick ups. Please email us to confirm that your bike is ready for pick up.

Repair priority is extended to essential workers, immunocompromised people and/or houseless folks. If you fall into one of these categories, or have a unique situation that defies category, please contact us at the shop or laurelcyclery@gmail.com.
