Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

iPhone 4 mount?

I have a Scott CR1 Team (2011) bike. I ordered (and waited forever) for a DURAGADGET iPhone 4 Bike Mount. It finally came today and doesn't come close to fitting around my handlebars. I have searched and all mounts I found say up to 1" diameter. My circumference is 4.2" so the diameter is almost 1.4". Do I have some kind of gigantic oversized handlebars (never noticed them looking large) or are all mounts made for baby bikes? Does anyone know of a iPhone 4 bike mount that will work?

Is this it?

Man, that's an ugly clamp -- can't say I've ever seen one like it before.

Are you sure your bars' diameter is 1.4"? The formerly-oversized standard now for road and mountain handlebars is 31.8 mm, which is 1.25". Sounds like you're counting the bar tape.

Here's one from Ram Mounts:

And another from USB Fever:

you know having your iphone in the sun like that Kills your LCD...

why don't you put it in your jersey pocket?

Personally, I wouldn't mount my iPhone on the bike. Partly because I think it's too exposed, but mostly because the only reasons to mount it would be to use it as a GPS-based cycling computer, and that kind of usage eats up too much battery. If I'm not riding long enough to suck down most of the battery, I'm not riding far enough to make GPS tracking worthwhile, IMO.

If I can charge it on-the-fly with my dynohub on a multiday tour, then that's another story.

I don't know how comfortable I would be with my iPhone on my bars. I personally have an armband and have it high and to the front. If I go down and it hits the ground, I would be more worried about my face because of the angle my body would have to be at in order for it to hit.

I have a 3gs and I rode a little bit with it... no noticeable problem with the LCD, and battery life kinda sucked, but the iphone 4 has a much better battery. All in all, the biggest problem with it for me is that you can't get caught in the rain with it.

Just use a blue tooth head set and put your phone away. The headset will allow you to answer calls and listen to music. Any other activities shouldn't be done on a bike anyway.

I'm not going to deny that enough heat will damage a LCD (or just about anything), but this explanation makes no sense. LCDs work by applying a voltage across two electrodes which changes the alignment of the liquid crystal molecules. This happens due to the electric field, and typically no current is drawn. Heat has nothing to do with it.

In any case, wind will do a pretty good job of cooling anything mounted to the bars. Even if you're sitting still in the sun on a 100F day, the iPhone has a temperature sensor and will shut off if it gets too hot. This is probably more to protect the electronics than anything else.

And finally, just about every bike computer ever made uses a LCD, whether it's a segmented display like a Cateye or a screen like a Garmin, and there's no mystical sun damage.

It's more than just a case, but I'm waiting for something like this:
https://www.wahoofitness.com/Fisica/W...ensor-Case.asp

It is water resistant and works with ANT+ sensors (speed, cadence, heart, power).
I'll wait for the reviews to find out battery life and how it behaves if you receive a phone call or txt.
Looks promising, but not cheap.

Broad oversummarization and a complete mistake on my part. I retyped a lot of it and left parts in that shouldn't have been there. Where I said "which generates heat," I meant to liken electricity to heat as both are forms of energy.

LCD panels do draw an extremely minimal amount of current to force the molecules to react. The electricity as a form of raw energy is what changes the crystals and allows them to block light from passing through when the voltage is applied. As heat is another form of energy, the crystals react to this in the same manner and block all light from passing through.


Either way I completely agree that heat can damage an LCD screen (done it.) but you normally need a means of retaining the heat around the panel. I toasted an old Nokia's LCD about 8 years ago when I left it on my dash. The iPhone's built in thermal switch will not prevent damage because it will only shut off the componentry but as you stated, the air around the phone will remove much of the heat from the unit.

A ziploc bag works. Heck, it even works to keep all my sweat off of it.

LCDs certainly can be damaged, or at least temporarily darkened, by sunlight. We have this problem with stopwatches used for timing in contests, if they are left on a table face up. I suspect it is UV related, but I'm not sure on that. A UV filter would then protect most LCDs designed for operation in sunlight.

As for bike computers, quoting from the Cateye Strada manual:
"Avoid having the computer in direct sunlight for unnecessary or extended periods."

I'm sure that there is a small leakage current across a LCD cell, but that's not how they operate. When an electric field (voltage difference) is applied, the electric dipole moments of the crystal molecules align with it (analogous to a bar magnet in straight magnetic field). They no longer rotate the polarization of the light, so it is blocked by the outside polarizer.

Heat might break up the crystal structure due to a phase change, and randomize the the polarization, giving you partial blocking. But that's a separate effect.

Regardless, none of this happens in practice except in extreme situations (left on a car dash, etc). So MrD's "sun kills your LCD" line is just silly.

The 1/8" of glass on the front of an iPhone will be a pretty effective UV filter if that's the case. And if heat is the problem, sitting on a hot tabletop is a lot different than on mount on moving bike.

Sounds like CYA to me. Yes, LCDs and electronics can be damaged by extreme heat. That doesn't mean that using one normally on a bike will cause it to explode.

Well it's the whole bit that if electricity is flowing, there will be some loss as there is no such thing as a perfect system. While it's not the current itself that causes the change, electricity is not like filling a bucket and draining it - it's a pipe with a few leaks.

I have had an LCD screen "burn-in" which is why I commented. I had those old Nokia bulletproof phones from 2001ish and when I left it on my dash, it permanently darkened the screen significantly - like I turned up the contrast a few notches. I had to turn it down to zero just to read it.

Hi there for road biking I use this thing called a Spiderpodium direct from www.breffo.com. There are some youtube vids of it in action but the music is way dodgy. the grip works really well though and I love that you can take it off and stick it in your pocket. I have a water backpack sometimes and I can tie the grip around that two which I actually quite like. It is very light as well and not bulky.

I tie the legs of the Spiderpodium around the break wires which holds it tight and I twist the other two legs together. It works on my commuter bike too. I posted these pics to thier user gallery there are others there too, but mine are the best ;-)

Well I got agressive. Drilled out the mount hole and used an extension nut and bent screw to fit around. It's not ideal but it is working. It will scratch and you can se 2 scratches where I tried to mount on the handlebars. Can't believe that they make mounts for only up to 1".

Oh, you were talking about the stem, not the handlebars themselves. No wonder you were having so much trouble.
