B&M Cyo Vs. IQ Fly

So, is the Cyo really much brighter than the IQ Fly? Does anyone have the new Cyo yet?

E6 on the left and IQ Cyo on the right, powered from the same source, in parallel. IQ Cyo consumes about 30% of the electric power consumed by E6.

According to the German magazine "Aktiv Radfahrer" the IQ Cyo N (the sport edition) is almost twice as bright as the IQ Fly, eg. 72 lux at 30 km/h versus 42 lux for the Fly:
http://www.radfahren.de/modules.php?...120&photonr=11

I own both lights, so here is my opinion; The IQ Cyo N is clearly better than the IQ Fly, not only is it brighter, but the on/off/auto switch is way better than the Fly's and can easily be used even with winter gloves on. The view of the Fly's switch is obscured by the body of the light and not easily manipulated while cycling.
With the Cyo one can also switch off the stand light so when you return the next day there will be light from the instant the light is switched on, even if the bike hasn't moved yet.

The IQ Fly is still a very good light and adequate for a lot of people. I still use mine on another bike and feel confident with to do some light off-asphalt night riding with it, but i wouldn't recommend choosing the IQ Fly unless it was at least 25% cheaper than the IQ Cyo.

Thanks for the links. I am getting a Cyo R to start with. Probably add a Cyo N down the road so I can see further down the road!

Too bad that my IQ Fly is really "bright enough" for where I ride. Still tempting to upgrade, but I think I'll wait until they make an off-the-shelf MC-E light.

I ended up getting the IQ Fly rather than waiting on the Cyo. I ended saving some money(not much of a difference probably $20) but also a lot of time. I think the next upgrade will probably be for an Edelux in a year or two when it has dropped in price from the $200 mark. Or, by then there might be another light that is brighter than the Edelux and I will just lay out the money for that. For now though I am quite content with the IQ Fly. It replaces the Fenix L2D and probably puts out a similar amount of lumens just in a more functional position. I also don't have to worry about batteries which is very very nice.

For me, IQ Fly was out of question because the need for a different mounting than E6 (and most dynamo halogens) would have produced an avalanche effect on my front. IQ Cyo has been a nice drop-in replacement for the E6.

I think SJS Cycles in the UK has them. No problem ordering from them either. I have ordered a few things from them, service is prompt and prices decent.

The IQ Fly has a 10,000 hr lifespan so I'll have to stew in upgrade fever for a while till it wears out. Im quite happy with the fly. Regarding the awkward switch, mine stays on senso permanently.

I'm eyeballing them at sjs (thanks for that link), trying to figure if they would mount to the fork crown and come out under the straddle cable for my canti-brake.

Hardy, give a call to Sammamish Valley Cycles in Redmond and see if they still have them in stock. The 85 or 90 Pounds that SJS is charging is only $3.00 less than what SVC is charging. Between shipping vs. tax I think you'd pay about the same.
Plus, you could bring your bike to the shop and test how it would fit before buying it.

It probably won't. I'm using B&M's alternate bracket for my Oval (on this page, marked 471U, and as pictured attached to the Oval headlight), and the brake wire straddles the bracket.

Well, maybe it would work, now that I think about it. You'd remove the Cyo light from its heavy-gauge wire mount, run the brake cable through the gap, then reattach the light. You'll need a long enough mount and might have to do some bending of it, but that's how I'd try doing it.

Check with Peter White Cycles. They just recently got in what was supposed to be a sizeable shipment. I got mine from them about 3 or 4 weeks ago.

My first high intensity German LED generator light so I cannot compare it with others but it does put out a LOT of light compared to the Shimano headlamp which came on the bike.

My personal fave LBS is stocking the regular IQ Fly! $99, they're asking, which is less of a bump over Peter White's prices than their usual increase above MSRP for components and geegaws. I think of it as a tax to keep them in business...

Redmond is just not in my normal ambit, though the shop sounds like one I'd like to visit. I go pretty much anywhere in Thurston County, some amount of exploring off from the freeway in Pierce, and otherwise it's gotta be right off I-5 farther north for me to swing through while on roadtrips for work.

I did just see a totally blinged out stealth LHT (all stickers removed but the Surly 4130 Natch) w/ schmidt hub and supernova on lefty mount. Honey brooks and nitto racks. Probably more details that I missed.

Got mine ordered from Peter White this week. The tone that he strikes on his web site is very off-putting to me, but the girl that I worked with was very nice and very helpful.

I agree that it probably won't go under the straddle cable -- it looks similar to the IQ Fly bracket, which definitely doesn't work that way (I've tried). But putting cable through the bracket might work.

The 471U bracket also works just fine with an IQ Fly, which is how I ended up mounting mine. But the Cyo is apparently heavier, so the weight might be too much.

Incidentally, you can also use that bracket with old centerpull calipers (though it requires some ingenuity and a file).

I've ordered the topal mount (472BA in the link above) for mine. Peter has said it will be strong enough--I just hope it will sneak under the straddle cable and be out and up far enough to a) not interfere with my cantis (shouldn't, but who knows), and b) not have some of the Cyo's light lost to the front wheel. I can always rig some handle bar mount I suppose, but I'm hoping this will do it.

Last word I had was that they will be in next week (of course, that word came last week...).
