Peak Design MC-S-1 Mobile Motorcycle Bar Mount Kit

The Peak Design MC-S-1 delivers a rock-solid, tool-free mounting solution for your phone, built around the SlimLink™ magnetic-mechanical locking system that snaps your device into place with a reassuring click. Engineered for 22-35 mm handlebars, this kit keeps your phone secure over rough terrain while offering instant portrait-to-landscape rotation.

Overview

The MC-S-1 is a complete mounting kit for cyclists, motorcyclists, and action sports enthusiasts who demand both security and convenience. It includes three interchangeable mounts: a Universal Bar Mount that clamps to 22-35 mm bars without tools, a GoPro-compatible mount for action camera rigs, and a 1/4"-20 mount for tripods and light stands. The system is part of the Peak Design Mobile Ecosystem, requiring a Peak Design Everyday Case or Universal Adapter (sold separately) to attach your phone.

What stands out

• SlimLink™ magnetic-mechanical locking: combines strong magnets with a physical latch for a fail-safe hold, yet releases in one second with a press of the side buttons.
• Tool-free Universal Bar Mount: installs in seconds on handlebars from 22 to 35 mm diameter, with a silicone-lined clamp that prevents scratching and absorbs vibration.
• Three mounts in one kit: switch between bar, GoPro, and 1/4"-20 setups without buying separate accessories.
• Premium materials: anodized aluminum, glass-filled nylon, and silicone ensure durability and weather resistance.
• Portrait or landscape: rotate your phone instantly without removing it from the mount, ideal for navigation or filming.
