I've had a few close passes on the road lately, so using inspiration from posts by @guerney I've bought one of these. As it comes, IMO it has several shortcomings:-
I bought a GoPro quick-release bracket long with two extensions arms and an extra base plate with the idea than I can quickly remove the complete arm when not required, or swap it between two bikes-
The base plates are fitted to the reflector brackets with the supplied 3M double-sided sticky pads, backed up with small self tapping screws
This is the assembled arm -
I drilled a couple of holes in the "lollipop" and used 2 - M6 x 16mm stainless flanged dome-head socket screws in the threaded holes in the arm.
My handlebars are too heavily populated to fit anything else, so I've attached the arm brackets to an accessory bar angled below the stem -
I've improved the daytime visibility using some red, white and orange reflective adhesive sheet, cut to shape.
The inner pivot is permanently tightened with a socket cap screw once positioned and adjustment is carried out with the thumb screw on the outer pivot. There is a spring washer immediately under the thumb screw to adjust tension so that the arm stays in place in a headwind but deflects without affecting the steering if hitting an obstacle.
A quick slackening of the thumb screw allows the arm to be swung forward over the front wheel while on the move -
It clears the brake lever and cables.
This is the rear view fitted to my "summer" hybrid -
..........and the front view on my "winter" hack -
I've given this a good testing on some of the worst pot-holed and rutted local roads (easy to find!) on both bikes and it works well. Drivers give me a very wide berth and it probably helps that the arm oscillates vertically slightly, improving the reflections. Time will tell if the plastic brackets will last, but I can always shorten the arm by leaving out the shorter extension to lessen the extended weight.
- The flimsy plastic bracket doesn't seem robust enough to last long and is intended to be fitted to the chain-stay or seat-stay. This places the reflector below a car driver's line of sight and is too far to the rear to discourage cutting in.
- Placed at the rear it's not possible to swing the arm in while on the move to negotiate obstacles or when on a cycle path, other than bashing it against something.
- My requirements are purely for day time and the reflectors alone aren't really sufficiently visible.
