Silly question but I'll ask, anyone mount their clicky/rotary to a bike? If so what did you use? I'm fiddling around with some old belt keeper from my duty belt but it's not quite working, any suggestions (other then duct tape or tie wire..:thinking
?
I have a simple, cheap method that I find more secure and free of "bounce" than any purchased mounts.
First, I take a small rectangle of foam rubber, only about 1" x 1.5". The source for this is a dollar store pair of black flip-flops. The soles are perfect material. I cut a V groove down the length of the one side, almost half way through, for the light to sit in. Then I cut another groove across the other side, for the block to sit on the handlebar. I like to clean up the grooves with a Dremel sanding drum, making nice round channels, but it's not necessary.
Then, with the light sitting in the block, on the bars, I pull a silicone wristband over the bezel, stretch it under the handlebar, and then up over the tail. You know the kind of wristbands kids wear, like the "Live Strong" yellow ones Lance Armstrong marketed. I bought a bag of plain black ones from an internet supplier, so they are neater and not weakened by any embossed logos, but I've never lost any of the embossed ones I used either.
Two or three #64 rubber bands will work, but they don't look as neat, and take longer to put on and off. I usually need to waste some length with those by doubling them around the light before going under the bars, or they are not tight enough. I started this way, and just using some white packaging foam, but evolved to the flip-flop soles and silicone band.
I've had a cheap 18650 light on my beater bike for about four years this way, no problems. What I like is it stays put, you have to feed the band around the bar to raise or lower the light, it won't creep while you ride. And because there is very little foam between the light and bar, it won't bounce over bumps. With the Twofish Lockblocks, it was like riding with a strobe light. Because there are two criss-crossing velcro bands, you have two holes in the rubber block between the light and the bar and this let's the light bounce around when you hit little bumps. Hated it.
