This is hands down the best phone mounting system we have found that best balances ease of mounting and dismounting, stability of the phone on the motorcycle and cost.
The kit comprises of the bar mount itself which can fit onto most size handlebars using either the large rubber mounting bands or small. The female locking plate has a high strength adhesive attached to it for mounting permanently only the back of your phone case but it still discreet and slim.
Simply attached the quadlock unit to the handlebars, and clip in your phone by push down and turning untill the system locks into place. To release, pull the sprung locking mechanism down, turn and remove the phone. Great design!
