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.
