Here I show you my version of the handlebar mount for the Garmin eTrex GPS handheld unit. The only thing that you really need to buy is a worm drive hose clip from your local harware store (mine cost about Rs.10/-). The wire for the mount can be any stiff length of wire e.g a bicycle spoke.
Tools needed are a plier to bend the wire and a screw to tighten the hose clip. This can be mounted on either a bicycle or motorcycle or maybe even places like a vehicles steering wheel or even a hang glider !!
What makes this so special is it's simplicity and good looks.
Step 1: The materials
First you need a worm drive hose clip as shown in the picture below. Make sure the diameter of the clip is sufficient for the handle bar you will be mounting it on. Also remember that the wire goes between the clip and the handle bar so the diameter needs to be slightly larger.
