UMS™ Mount Arms

About UMS™ Arms and Adapters

We offer a variety of arms, adapters, and extensions to mount lights and accessories in highly visible locations on the bike.  The modular nature of the extensions and adapters allow for a great degree of customization.  All mount arms require a UMS™ mount of some type to attach the arm to.  Extensions may or may not be necessary depending on your application.

Estimating The Best Fit

Use the Sizing Template to cut out each mount and arm of interest.  Next, hold the cutouts up to the mount position on the bike to accurately estimate where the mount point will be positioned.  Cut out extensions and tape them to the mount and arm cutouts as needed.  This will help you easily determine how mounted accessory will be positioned.

COVID-19 Impact

COVID-19 is impacting us all. By now you have received notifications from everyone related to this serious crisis. Bup Labs is still open for business, but we are also providing help to various entities related to COVID-19 care. As a result of the additional efforts and the lack of some supplies used in our manufacturing processes, our production has slowed. We have taken extra precautions to ensure environmental safety is adhered to for both incoming and outgoing products and materials. We appologize for the delays and ask for your patience during this trying time.
