Our take on the MJ-6512 Aluminum Garmin Handlebar Mount

The Magicshine MJ-6512 is an aluminum handlebar mount that holds Garmin devices and most Magicshine bike lights. It clamps to handlebars from 28mm to 35mm, so it fits road, gravel and mountain bars without shims. The metal body is stiffer than the plastic mounts many lights ship with, which keeps heavier lights from bouncing on rough ground. It suits riders who want one mount for a Garmin computer and a Magicshine light, though it is a single-purpose part rather than a universal adapter.

Pros
  • Aluminum body resists flex and vibration better than plastic mounts
  • Fits handlebars from 28mm to 35mm without extra shims
  • Works with Garmin devices and a long list of Magicshine lights
  • One mount can carry a computer or a light, cutting clutter
  • Simple clamp design with no electronics to fail
Cons
  • Compatibility is limited to Garmin and Magicshine, not other brands
  • Does not fit handlebars outside the 28–35mm range
  • Adds a separate part to buy if your light already includes a mount
  • No quick-release lever described; swapping devices takes a tool
