My PB superflash (and a host of other) lights keep flying off due to potholes and such. Instead of buying more disposable taillights, I'm looking to the DiNotte.

So how secure is the mount? Blowing a $25 light sucks. Tossing another $100+ is flat out unacceptable even once. Think Cannondale hardtail hitting bad rail tracks at 35 MPH. Every damn day.

Is the Superflash flying apart or coming out of its mount?

It takes a lot to dislodge one of those--I've taken my hardtail over a lot of bone-rattling bumps (never 35 MPH, maybe that's my problem ) and never lost a Superflash, although I have lost lights that were mounted less securely.

Two in two weeks. One strap mounted and another properly in it's bracket. Nevertheless, I'm moving on if the DiNotte is sufficiently secure.

I cross tracks every day on my hardtail and haven't lost my Dinotte tail light yet.
I even bomb down some singletrack and it has never fallen off.
Even wiped out a couple times with no mharm to the Dinotte.
You will LOVE the Dinotte.
It's worth the price.

The rubber O-ring is surprisingly secure and indestructible when not mounted to the flimsy seatpost attachment it comes with.
The rubber it uses is way more durable than plastics.

I hit a pothole yesterday hard enough to flat-spot the rim. All three DiNottes stayed put. I had to adjust the aim of one of the headlights. My taillight is mounted to a leg of my rack, so I can't speak for the seatpost adapter thingie.

The Dinotte holds well when mounted to the seatpost by itself I find. When you use the improved seatpost mount that's supplied right now it allows you more angling of the light so you can aim it high to wake up drivers close to you or aim it mid way for long range visual detection.

I find that the supplied improved tail mount rocks for positioning the light but I've not tried it on jumps and such as I got the Dinotte before the snow fall and my normal bike with shocks was in the shop and I didn't get that bike till after the snow came. It's warming up right now and most snow is melted off right now. Once the roads are rained out to get rid of the salt on the roads I'll see how well that improved mount holds on the bike.

Another idea which I borrowed off Derath (hope I got his name right) on BF is I got a Topeak Aero quick-release medium seatbag for quick on/off while riding/shopping and to keep some tools in it and the Dinotte mounts perfectly underneath the bag. It's like it was meant to be there. I think Derath tied his Dinotte to the under part of the bag. I did the the same as a fail-safe backup so that I know that tail light is not going to be lost because it's tied to the elastic straps underneath the bag and also the battery is inside the bag zipped up so I have double protection.

The Topeak Aero quick-release bag comes in if I'm correct 4 sizes. I have already called Topeak up and spoke with thier design team and the mounting clips are rated at 4lbs max. for all bags. The medium bag also has a zip out extention of about 1in if you need it.

Not quite sure what the straps are used under the bag but they work out for the Dinotte tail light. I've not tested the extra blinkie holder on the bag yet but it's there if you need it.

Hope this helps.

O-rings > clips. Every time.

I haven't lost my PBSF yet (think Cannondale CAAD8 on cracked asphalt at... well, half of 35 mph ), but I might just be lucky, too. One thing it's got going for it is what it's one of the lightest blinkies on the market, so it doesn't stress its clip as much as larger lights stress theirs.

However, I could probably almost kick the Dinotte and it'll stay put. The mount is more secure, and since the batteries are separate, the "light engine" itself is also quite, um, light.

Honestly, if you can't figure out how to keep a superflash securely mounted to the bike, I really don't think you should be looking to spend $100 on a dinotte.

I own a dinotte, but I wouldn't recommend them to anyone. I'm still kinda pissed at them over their lack of a proper mount to start with, then the shoddy mount they finally did release (that I was stupid enough to pay for).

What i guess I'm saying is that if my dinotte fell off tomorrow, I would go back to using the superflash and not even consider replacing it.

Have you tried zip-tying the Superflash in place? That's what I have done, mostly to make sure little elves don't take it out. The only drawback is that I need new zipties every 2-3 weeks when I recharge the batteries.

The PB Superflash mount is simply inadequate for me. Many other light brands have fallen to this stretch. Instead of pouring more money after bad it's time to move on.

I use a terracycle mount for my Dinnotte:

You can essentially pickup the entire bike from the mount, and the lights aren't going anywhere.

I've used the Dionette supplied mount (with O rings) on my seatposts and it's held up very well.

IMO, taillights should be single unit, not a battery pack and the light engine in two separate pieces. For the amount Dinotte charges on the 140L, I expect a better mounting system. I do a lot of stop and go on my bikes, fiddling around with the Dinotte is not something I'm willing to put up with.

For the Superflash, use JB Weld or Superglue.

I haven't put it to the thief test yet, but it seems like the Dinotte is so low-profile that people won't necessarily notice it's even there.

It doesn't take long to undo, either. Longer than a quick release, of course, but quicker than any screw-on mount.

Another bonus of the separate battery pack is that the light has a really low profile. Post #17 in this thread asks for a low profile light that would be less likely to get bumped around. The 200L on my road bike isn't any taller than a Cateye Strada computer, and is hardly longer than the thickness of the handlebar tubing itself.

The non-rigid O-ring has its benefits, too. It stays put when you want it to stay put, but it's easy to re-aim on the fly (point it down to avoid blinding pedestrians or riders to your rear, then point it back up when you're back among the cars). My rigidly-mounted lights can't be adjusted as easily.

Taken altogether, with the battery packs mounted under the front stem and between the saddle rails (each nearly as accessible as a self-contained quick-release light), stable mounts, and small size, the Dinotte lights work very well.

I'll have pics of my Dinotte quick release setup in the seatbag up this weekend on my image website. My setup is very simple (copied off Derath) which I just take the seatbag off via the positive locking Topeak quick release. I think you can get smaller Topeak bags with the elestic mounts.

It's super easy to take on/off and kinda like a self contained unit right now. With a small bag/backpack on you, you can put a biner on it and snap the seatbag on it while you're off shopping/etc then when you come back to the bike un-biner the bag and snap onto the seat, unlock the bike, and you're off.

The backpack is a Deuter Race Exp Air which some people have asked me for some pics of the mesh back.

Got many angles of the light mount on the bag. It's late so I've not bike mounted it yet but you can see the QR on the top for easy on/off no fuzz.

Dinotte owner here. No problems with the mount, I move it very frequently from bike to bike. The only thing I might suggest is that you replace the o-ring periodically, just cheap insurance.

Also, if you're real worried you can make sure you've got the power cord secured in such a way that if the light does come off, the cord will keep it from getting lost.

How did you get it on your rack? I might try the same.
I LOVE THESE LIGHTS!!

Sorry to disagree, I love the dinotte mount! Quick, easy on/off.

loop the O-ring around the rack support once, this should shorten up your O-ring enough to allow your dinotte to be mounted securely to one of the rack supports.

Since the DiNotte light engine is round, another option is to use some sort of clamp band around it. For example, the rubber-cushioned P-clamps you can get at hardware stores... pick one that fits the DiNotte engine, one that fits your frame (or rack strut, or whatever), sandwich an aggressive lockwasher between them and bolt 'er up. I was experimenting with the ubiquitous Cateye reflector/taillight bands the other day, and the only hangup is that they don't "mate" well enough against eachother to prevent swivelling. Back to the drawing board...

I suppose another option would be to open up the DiNotte, determine where it's safe to drill, and then drill & tap directly into it like the 600L light engine.

As for the SuperFlash, if you get an O-ring that fits around its "waist" and around the rear of the slide-in mount, that should help it stay put during high-G maneuvers

While my light has never come off at all, the mount was sliding around my seatpost on my old bike - due to some rough road riding. I could have used a smaller o-ring, but I didn't have one - I wanted to use what I already had - a worm gear hose clamp. I just cut two slits in the mount using a dremel w/ cutting wheel attachment, than ran the pipe clamp through them and around the seatpost and tightened the screw with a nutdriver. I made the slits right where the o-ring couples, and only in the middle, so the o-ring can still be used. This was much more secure, but again, the light or its mount never came off in the least bit. The same goes for my Dinottoe headlight - the light sometimes does move around the handlebar when the bike takes a big jolt, but it's never come off.

After buying the new bike, I am no longer using the hose clamp - for one, because the taillight mount works well as is on it, and two, because it would be too much of a hassle to re-attach the clamp every time I want to switch bikes.

If you have problems with the new taillight mount moving on you, using the above method may be a good idea. I've meant to post pictures, but haven't gotten around to it yet... maybe on Tuesday. For now, if you want to try cutting the slits I've mentioned, I suggest using a used (smaller diameter) cutting wheel, because a new one may make slits too wide. The plastic on the mount is soft enough that I wasn't worried about shattering, but beware that the foam on the mount will melt (where the slits are made) when doing this.

Looks like this:





Then the battery pack can be velcroed to a rack crossmember:

A couple of tiny pieces of duct tape will solve it. I use gorilla brand and it lasts forever and is very strong.
I have a piece around the lens to keep it from popping off and one from the bottom of the clip to the back of the light which keeps it from popping out of its mount. A ziptie would probably work, too.
