Rokform Motorcycle Stem Phone Mount — Aluminum (Black), Low-Profile Twist Lock & Safety Lanyard

The Rokform Motorcycle Stem Phone Mount is a CNC-machined aluminum stem mount that secures RokLock-equipped phones to sport bike center stems while allowing angle adjustment and added safety lanyard protection.

Made specifically for sport bikes and bicycles with clipped handlebars, this low-profile stem mount fastens to center stems measuring 12–24 mm. It pairs with Rokform RokLock cases and uses dual magnetic retention plus a Twist Lock to lock your phone in place, and stainless steel hardware delivers long-lasting durability. The mount ships with two adjustable inserts to fit a broad range of stems and includes a safety lanyard for an extra layer of protection during aggressive rides.
