It seems like a lot of the flashlight mounts for bicycle handlebars are built cheap and flimsy. Is there a good brand mount that stays still and doesn't wobble or bounce when you ride? I once had a Two-Fish and it was basically crap. How about a mount that actually stays put when you go over a bump? A lot of the ones online have velcro or other straps and rubberized parts. That's too loose and just won't hold up well.

If you ride for a while or go over a bump, the mount slips and next thing you know the flashlight angle sags low and you have to re-adjust it and tighten it again. I'd be looking for something to hold an 18650 or 26650 light, but it needs to be rock solid without wobbling or losing its grip during a rigorous rough ride. Is there any such animal out there?

Thanks.

You weren't satisfied with your Twofish but I've used a couple of them extensively and they work for me. One's on the helmet with a AA light and the other I've used on the handlebars with an 18650 P7 flashlight. Then there's another we've used for a tail light on another bike with a red LED 501B flashlight. All hold the flashlights reliably; they stay in place and hold up well.

The heaviest light of those three weighs about 6 ounces. I'm sure there's a limit on how heavy a light these holders will keep in place but a single 18650 light seems to be well within their limits.

I balance the flashlight on the Twofish and cinch the Velcro tight. They all go on and off quickly and stay in place. In fact, while they stay in place, some other lights I've used, such as the MJ 808, are prone to rolling forwards and down on the same handlebar. With some of those other lights I've added a strip of inner tube as a shim to reduce slipping. But I haven't needed that with the Twofish; they hold just fine.

Perhaps there are surfaces that the Twofish doesn't grip as well. I have run of the mill, round, aluminum Cannondale handlebars.

I've used this mount with this light on my bike. It does tend to tilt every now and again, but no biggie putting it back- and that light isn't slipping out of the mount. The mount slipping could probably be addressed by using some friction tape or some old inner tube between teh mount and the bar- used that trick a time or two mounting rear blinkies

Ditto to the $2 U mount. It only holds 1" diameter flashlights. I found the velcro on the bars to be not a great choice. I recently upgraded to XinTD C8 V5 XM-L2 U2 1A 18650 Flashlight this flashlight and I have to say I really like it for $30. The beam is pretty tight and it's bright if you use 3400 mAh 18650s. I can ride 20 mph and see far enough down the road to feel safe.

Don't be fooled by the $2 price of the U mount. It's a winner. I've been using the same one for at least three years and it's still rubbery and supple. The two fish style velcro mounts are OK for helmet flashlights. Of course you purchase the ones where the two velcros are at 0º not 90º angle.

If the two fish bracket is slipping, clean the bars and the contact part of the bracket with Windex, and a clean rag. Make sure you don't even have finger prints on the mating surfaces.
