Good news for those of you who were unfortunate enough to have dropped $130 on the Wahoo RFLKT (ROFL!) Bluetooth 4 iPhone HUD for your bike. One of the best iPhone cycling apps – Cyclemeter – has just been updated to support your fragile dongle. There’s bad news, too: You’ll have to drop another $3 on an in-app purchase to enable the new feature. Insult, meet injury.

The promise of the Wahoo RFLKT is of a tiny, ultralight box with an LCD readout which displays information from an iPhone cycling app on the handlebars of your bike. You get the advantage of using your favorite tracking app, and also of having an easy to read and control HUD, instead of having to buy an expensive GPS-enabled bike computer.

The reality comes somewhat short.

So you just had your own personal iPhone 5 unboxing. What next? If I were you, I’d hop on my bike and go burn a few calories, taking in the sunny view of the city as I go. But where would I put my new toy? After all, there are no iPhone 5 handlebar mounts available yet. Or maybe you live somewhere rainy and dull, and you want to keep your iPhone in a pocket or bag.

Luckily, the RFLKT now exists. It’s a little LCD bike computer that sits on your handlebars, only instead of just spitting out your speed and lap times, it displays sports info beamed to it from your iPhone — 5 or otherwise.
